Chloroplast genomic diversity in Bulbophyllum section Macrocaulia (Orchidaceae, Epidendroideae, Malaxideae): Insights into species divergence and adaptive evolution

Bulbophyllum is the largest genus in Orchidaceae with a pantropical distribution. Due to highly significant diversifications, it is considered to be one of the most taxonomically and phylogenetically complex taxa. The diversification pattern and evolutionary adaptation of chloroplast genomes are poorly understood in this species-rich genus, and suitable molecular markers are necessary for species determination and phylogenetic analysis. A natural Asian section Macrocaulia was selected to estimate the interspecific divergence of chloroplast genomes in this study. Here, we sequenced the complete chloroplast genome of four Bulbophyllum species, including three species from section Macrocaulia. The four chloroplast genomes had a typical quadripartite structure with a genome size ranged from 156,182 to 158,524 bp. The chloroplast genomes included 113 unique genes encoding 79 proteins, 30 tRNAs and 4 rRNAs. Comparison of the four chloroplast genomes showed that the three species from section Macrocaulia had similar structure and gene contents, and shared a number of indels, which mainly contribute to its monophyly. In addition, interspecific divergence level was also great. Several exclusive indels and polymorphism SSR loci might be used for taxonomical identification and determining interspecific polymorphisms. A total of 20 intergenic regions and three coding genes of the most variable hotspot regions were proposed as candidate effective molecular markers for future phylogenetic relationships at different taxonomical levels and species divergence in Bulbophyllum. All of chloroplast genes in four Bulbophyllum species were under purifying selection, while 13 sites within six genes exhibited site-specific selection. A whole chloroplast genome phylogenetic analysis based on Maximum Likelihood, Bayesian and Parsimony methods all supported the monophyly of section Macrocaulia and the genus of Bulbophyllum. Our findings provide valuable molecular markers to use in accurately identifying species, clarifying taxonomy, and resolving the phylogeny and evolution of the genus Bulbophyllum. The molecular markers developed in this study will also contribute to further research of conservation of Bulbophyllum species.

A new species of Neohydatothrips (Thysanoptera: Thripidae) from India.

With 120 described species (ThripsWiki 2020) Neohydatothrips is the most species-rich genus in the Thripidae subfamily Sericothripinae. Although widely distributed almost 70% of the species are from the New World (Lima Mound 2016), with only seven species recorded from India (Rachana Varatharajan 2017). The biology of most species in the genus remains unknown, but they apparently feed and breed on the leaves and/or flowers of various unrelated plants. A few species are economically important as plant pests as well as virus vectors, such as N. variabilis (Beach) (Zhou Tzanetakis 2013; Lima Mound 2016; Han et al. 2019). N. samayunkur (Kudo) is a pest on flowers and leaves of Tagetes spp. in many countries including India (Nakahara 1999; Bhatti et al. 2003). Even though N. gracilipes (Hood) was described originally as damaging cotton in Mexico, it is associated with weedy species of Sida in several countries including central India (Lima Mound 2016). In southern China, N. flavicingulus Mirab-balou, Tong Yang is reported as damaging leaves of Manglietia fordiana. In California, avocado crops are sometimes damaged by N. burungae (Hood) and this species is also recorded as distorting the young leaves of Passiflora in Colombia (Mound et al. 2019). N. gracilicornis (Williams) is reported as damaging Pinaceae and Betulaceae in Spain and South Italy (Marullo 2009). The purpose of this article is to describe a new species from India that was collected in the flowers of Jasminum sambac (Oleaceae) in Assam, northeastern India. A detailed structural diagnosis of this genus is provided by Masumoto and Okajima (2020).

The striking endemism pattern of the species-richest snake genus Atractus (Dipsadidae: Serpentes) highlights the hidden diversity in the Andes

Abstract The distribution of the highly diversified and species-rich snake genus Atractus was assessed in search for endemism areas. The dataset of 6000 museum specimens was used to run an Endemicity Analyses in order to identify areas of biogeographic relevance for the genus Atractus. By using distinct methodological approaches and modifying the size and shape of grid cells we obtained a better adjustment to each species range, taking into account species distributed along the Andean and Atlantic Forest mountain ranges or certain vegetation constraints. Three scales of endemism were observed: micro endemic areas, represented by three different regions; intermediate sized endemic areas, represented by nine different regions; and macro-endemic areas, represented by four different provinces. Although most assessed regions corroborate well-defined biogeographic units according to the scientific literature, some, mainly located in the Colombian Andes, are not regularly considered in biogeographic syntheses carried out for vertebrates. Methodological approaches, along with a well curated database and taxonomic accuracy, may significantly influence the recovery of endemism areas, mainly considering mountain topography and local niche structure. The results present herein highlight the relevance of three Colombian Cordilleras, in order to completely understand Neotropical biota patterns of distribution. It is important to note that a well-resolved taxonomy represents both the framework and the first step toward a comprehensive biographical synthesis reducing Wallacean shortfalls in biodiversity.

Diversity and phylogeny of Paradiplozoon species (Monogenea: Diplozoidae) parasitising endemic cyprinoids in the peri-Mediterranean area, with a description of three new Paradiplozoon species

The Diplozoidae are monogenean parasites of mainly cyprinoid fishes with a unique life cycle, whereby two larvae undergo anastomosis and fuse into a single cross-shaped specimen. Paradiplozoon is the most species rich and widespread genus of the family, with a distribution range covering Eurasia and Africa; however, some areas remain underexplored and their diplozoid fauna is uncertain. In the present study, the Paradiplozoon diversity was investigated in the peri-Mediterranean region, which has the highest levels of cyprinoid diversity and endemism in Europe. A total of 36 endemic cyprinoid species were sampled from sites in north-west Africa and the southern European peninsulas and investigated for the presence of diplozoid parasites. Of five Paradiplozoon species collected, three were identified as new to science: Paradiplozoon moroccoensis n. sp. from the Moroccan endemic Luciobarbus lepineyi; Paradiplozoon ibericus n. sp. from Iberian endemic cyprinids and leuciscids and Paradiplozoon helleni n. sp. from the Greek endemic Scardinius acarnicus and Tropidophoxinellus hellenicus (descriptions provided herein). In addition, new host records for P. homoion and P. megan are presented, with the former being most prevalent in the investigated region. Phylogenetic analysis supported paraphyly of the genus Paradiplozoon, and suggests the need for a careful taxonomic re-evaluation of this genus. Furthermore, the results showed that endemic Paradiplozoon of the peri-Mediterranean do not form a monophyletic group, suggesting multiple origins of this parasite groups in different peri-Mediterranean regions.

Ethnobotanical Uses, Phytochemistry and Pharmacology of Different Rheum Species (Polygonaceae): A Review.

Today, there is an increased tendency to use herbal remedies. Rhubarb refers to several species of the genus Rheum L. in the Polygonaceae family. This species-rich genus is mainly distributed in Asian countries. Several medicinal effects have been attributed to the Rheum spp. in the traditional and modern medicine such as healing lungs, liver, kidney, womb and bladder diseases, cancer, diabetes, insect bites, relapsing fevers, diarrhea and constipation. Various in vitro, in vivo and clinical studies have investigated the therapeutic effect of extracts, fractions and pure compounds isolated from different species of this genus. Considering the positive findings, several pharmaceutical formulations containing rhubarb extract like capsules, drops, mouthwashes and different topical formulations are now present in the market. However, there are other traditional therapeutic effects of rhubarb that have not been studied yet and it is of great importance to perform confirmatory experiments or clinical investigations. The current review summarizes general information regarding botany, phytochemistry, ethnobotany and pharmacological aspects of Rheum spp. It is hoped that the present review could motivate subsequent research on the other medicinal properties of these plants that have been neglected until today.

Мучнисторосяные грибы (Erysiphaceae) Ферганской долины (в пределах Узбекистана): первый аннотированный список видов

A first annotated checklist of powdery mildews (Erysiphaceae) recorded from the Fergana Valley (within Uzbekistan) was compiled on the base of original long-term research, revisions of previously collected specimens deposited at Tashkent Mycological Herbarium of the Institute of Botany of Academy of Sciences of Uzbekistan (TASM), and earlier publications of other mycologists and phytopathologists. In total, 67 erysiphaceous species of ten genera on 153 angiosperm host plant species of 100 genera and 37 families have been recorded, including 21 species and 1 variety found for the first time in the Fergana Valley. The most species-rich genera in the investigated area are Leveillula (16 species), Erysiphe (15), Podosphaera (12), Golovinomyces (10), and Phyllactinia (8), whereas the genera Arthrocladiella, Blumeria, and Sawadaea are only represented by a single species per genus. Such a particular taxonomic composition of powdery mildews can be considered typical for Central Asia, especially with regard to the prevailing position of Leveillula. The present checklist contains detailed information about all particular findings for each powdery mildew species: recorded host plant species, typical habitats, collection locations, collection dates, collectors’ names and TASM herbarium specimen numbers. The most common species are Blumeria graminis, Erysiphe cruciferarum, E. trifoliorum, E. polygoni, Golovinomyces artemisiae, Leveillula alhagi, L. cylindrospora, L. lappae, L. papilionacearum, L. picridis, L. taurica, Podosphaera clandestina, P. pannosa, P. xanthii, Phyllactinia babayanii, P. fraxini, and P. moricola; whereas all other powdery mildew species are relatively rare.

Apocynaceae in the Atlantic Forest of Rio Grande do Norte, Brazil

Abstract We present here a taxonomic study of Apocynaceae from the Atlantic Forest remnants in the state of Rio Grande do Norte (RN), Northeast Brazil. Twenty-four species in 18 genera, distributed in Apocynoid grade (3 genera/5 species), Asclepiadoideae (8 genera/10 spp.), and Rauvolfioid grade (7 genera/9 spp.) were recorded. The most species-rich genera were Aspidosperma, Ditassa, and Mandevilla with three species each. The other genera were represented by one species each. Five genera and seven species were recorded in Rio Grande do Norte for the first time. Descriptions, identification key and comments on distribution and taxonomy of both genera and species are presented, as well as illustrations and figures.

Reproductive biology and sexual dimorphism of the poorly known frog Chiasmocleis alagoana (Microhylidae, Gastrophryninae), with an updated diagnosis for the species

ABSTRACT Chiasmocleis is the most species-rich New World microhylid genus. Among Atlantic Forest species in the genus, C. alagoana has the northernmost distribution. The species was described two decades ago; however, little is known about its natural history. Herein, we provide information on its reproductive biology, advertisement call, and external morphology based on specimens from the type locality and the type series. Reproduction occurs in the rainy season but only on days with torrential rains. The advertisement call consists of a series of pulsed notes common for most species of the genus. Structurally, each note consists of two groups of distinct pulses with amplitude modulations. This call structure is a candidate of synapomorphy for a subclade of the genus consisting of C. alagoana, C. cordeiroi, C. crucis, and C. schubarti. Morphologically, the species exhibit sexual dimorphism with females being larger and twice heavier than males. Both sexes have fringes on fingers and toes. Moreover, we report the presence of dermal spines over the body and webbing on feet in males and include these characters in an update diagnosis of the species.

Динофлагеляти Кримського півострова та його морського прибережжя

The article is devoted to the generalization of the existing information concerning dinoflagellates of the Crimea. A list of dinoflagellate species of continental waters of the peninsula and the Crimean coast (Black and Azov seas) of Ukraine was compiled. It is based on the analysis of literature and original data obtained in 1987, 1992-1993 and 2011 in the Black Sea. The list of dinoflagellata species of Crimea includes 196 species (206 infraspecific taxa) belonging to 64 genera, 36 families, 15 orders and 3 classes. Eighteen species have been recorded in the fresh and salt water bodies and mud volcanoes of the least studied continental part of Crimea; half of them were also found in marine waters. Dinoflagellates of the Azov coast of Crimea and the Kerch Strait are similar in number of species, but differ significantly in composition (26 and 31 species, respectively; only 13 (25%) of them are common). The greatest number of species of dinoflagellates found on the Black Sea coast of Crimea. It is almost half of all species known for the Black Sea (196 and 447, respectively). To compare the species richness of dinoflagellates from different regions of the Crimea, survey data covering all areas in a short period of time are of great importance. A total of 74 species of dinoflagellates belonging to 3 classes, 11 orders, 22 families and 30 genera were found off the coast of Crimea. The most species-rich genera are Protoperidinium Bergh (17), Dinophysis Ehrenb. (8), Gymnodinium F.Stein (7) and Prorocentrum Ehrenb. (6). Based on the analysis of original and literature data and the criterion of similarity of the species composition of Crimean dinoflagellates, it’s division into five algofloristic regions is proposed: the western Black Sea coast of Crimea (from Karkinitsky Bay to Cape Aya); southeastern (from Ayia to Takil), Kerch Strait, Azov coast of Crimea and land (which, in turn, is divided into steppe and mountainous Crimean regions). It is in compliance with the algofloristic zoning of Ukraine.

The genus Lycianthes (Solanaceae, Capsiceae) in Mexico and Guatemala.

Lycianthes, the third most species-rich genus in the Solanaceae, is distributed in both the New and Old Worlds and is especially diverse in Mexico. Here we provide an identification key, taxonomic descriptions, distribution maps, and illustrations of specimens, trichomes, flowers, and fruits for the 53 known Lycianthes taxa of Mexico and Guatemala. The new combination Lycianthes scandens (Mill.) M.Nee is made and replaces the name Lycianthes lenta (Cav.) Bitter, which is placed in synonymy. Within L. scandens, two varieties are recognized (Lycianthes scandens var. scandens and Lycianthes scandens var. flavicans (Bitter) J.Poore & E.Dean, comb. nov.). In addition, one new species (Lycianthes rafatorresii E.Dean, sp. nov.) is described from eastern Mexico, and 10 names (either recognized taxa or synonyms of recognized taxa) are lectotypified, including the names Solanum heteroclitum Sendtn., S. rantonnetii Carrière, and S. synantherum Sendtn. The species L. multiflora Bitter and L. synanthera (Sendtn.) Bitter are excluded from the treatment, as research indicates that they do not occur in Mexico and Guatemala, however full synonymy for both names is given.

Increasing knowledge of the denizens of saline environments through integrative taxonomy: new Argentinian endemic taxa of Liolaemus (Iguania: Liolaemidae) and their evolutionary relationships

The known diversity of the genus Liolaemus continues to increase, principally due to its great degree of endemism, the increasing number of researchers working on it, and advances in the taxonomic and phylogenetic knowledge of the genus. This diversity positions Liolaemus as the second most species-rich tetrapod genus. The present work adds to evidence for the great diversity of Liolaemus through the description of two new species, endemic to saline environments in the Argentinian Puna. Both species are members of the Liolaemus montanus group within the subgenus Eulaemus. To determine the taxonomic status of these lizards, we used integrative taxonomy as a tool, incorporating phylogenetic, morphological, and molecular genetic evidence, as well as the anatomy of hemipenes, statistical morphological analysis, and ecological characteristics. Our analyses supported the conclusion that both sampled populations of lizards are species new to science. One of these is found along the margins of the Antofalla salt flats in the Catamarca Province and the Hombre Muerto salt flats in the Salta Province. The other new species inhabits saline habitats vegetated by Lycium humile, principally between the salt crusts of the Antofalla salt flats. Both species are small to medium sized and can be distinguished from all other species of the L. montanus group by unique combinations of morphological characters, primarily pholidosis and dorsal and ventral colour patterns. urn:lsid:zoobank.org:act:29B39613-3298-4B43-A13A-9F950051BD04 urn:lsid:zoobank.org:act:A97A5AA8-7295-4882-9809-CEFAD72E7202

Cutting the Gordian knot: a historical and taxonomic revision of the Jurassic crocodylomorphMetriorhynchus

AbstractMetriorhynchidae was a clade of extinct crocodylomorphs that adapted to a pelagic lifestyle, becoming a key component of Mesozoic lagoonal and coastal marine ecosystems. The type genus Metriorhynchus is one of the best-known genera of Mesozoic crocodylomorphs, and since the mid-19th century, the ‘concept’ of Metriorhynchus has become associated with the referred species Me. superciliosus. Historically Metriorhynchus has been the most species-rich genus in Metriorhynchidae, with most Middle Jurassic species and many Late Jurassic species referred to the genus at some point in their history. However, the type species Me. geoffroyii has largely been omitted in the literature. Its type series is a chimera of multiple metriorhynchid species, and a type specimen has never been designated. Moreover, phylogenetic analyses have repeatedly shown that the 19th–20th century concept of Metriorhynchus is not monophyletic – to the point where only referring every metriorhynchid species, and some basal metriorhynchoids, to the genus would render it monophyletic. Herein we designate a lectotype for Me. geoffroyii, re-describe it and restrict the genus Metriorhynchus to the type species. We also establish the new genus Thalattosuchus for Me. superciliosus, thereby cutting the ‘Gordian knot’ of Metriorhynchus with Th. superciliosus.

Two new genera of Sapindaceae (Cupanieae) from the southern Pacific: Lepidocupania and Neoarytera

Buerki, S., J. Munzinger, P.P. Lowry II & M.W. Callmander (2020). Two new genera of Sapindaceae (Cupanieae) from the southern Pacific: Lepidocupania and Neoarytera. Candollea 75: 269–284. In English, English abstract.Phylogenetic analyses of the family Sapindaceae inferred from nuclear and plastid sequence data have revealed a high level of para- and polyphyly at the subfamilial, tribal, and generic levels. A phylogenetic study focusing on taxa in the southern Pacific belonging to tribe Cupanieae has shown that the two most species-rich genera, Arytera Blume and Cupaniopsis Radlk., are polyphyletic. This study aims to clarify generic limits among the taxa currently placed in these two genera by identifying morphological features that support monophyletic groups suitable for recognition at the generic level. Specimens deposited in major herbaria holding material of these taxa were examined to complement extensive field observations. Careful consideration of morphological features in light of previous taxonomic treatments and the results of phylogenetic analyses enabled us to propose a re-aligned generic framework for Cupanieae in which two new genera are described to accommodate species previously placed in Arytera and Cupaniopsis: viz., Lepidocupania Buerki, Callm., Munzinger & Lowry (21 species) and Neoarytera Callm., Buerki, Munzinger & Lowry (4 species). A total of 25 new combinations are made, lectotypes are designated for nine names (two first step and seven second-step), and one new synonym is established. A key to the newly circumscribed genera Arytera and Cupaniopsis, along with allied genera, is provided, accompanied by information on the distribution and ecology of each species.Received: June 26, 2020; Accepted: August 28, 2020; First published online: October 29, 2020

Some distinctive new species of Psychotria (Rubiaceae, Psychotrieae) from Madagascar

Taylor, C.M., R.E. Gereau & H.H. Schmidt (2020). Some distinctive new species of Psychotria (Rubiaceae, Psychotrieae) from Madagascar. Candollea 75: 159–182. In English, English and French abstracts.Psychotria L. (Rubiaceae, Psychotrieae) is an unusually species-rich genus in Madagascar. Recent botanical explorations here have found a number of undescribed species, and some unusual morphological structures for this genus. Here ten new Psychotria species from Madagascar are formally described: Psychotria ambatovensis C.M. Taylor, Psychotria antilahimenae C.M. Taylor, Psychotria birkinshawiana C.M. Taylor, Psychotria davisiana C.M. Taylor, Psychotria eumachioides C.M. Taylor, Psychotria hamifera C.M. Taylor, Psychotria mutabilis C.M. Taylor, Psychotria notopleuroides C.M. Taylor, Psychotria palifera C.M. Taylor, and Psychotria razafimandimbisonii C.M. Taylor. Unusual morphological features of some of these species include a prostrate habit, deeply retuse leaves, and enlarged, persistent, funnelform stipules. Assessment of the conservation status of these using IUCN Red List categories finds four of them “Vulnerable” and six “Endangered”.

Evolution of pollination syndromes and corolla symmetry in Balsaminaceae reconstructed using phylogenetic comparative analyses.

Floral diversity as a result of plant-pollinator interactions can evolve by two distinct processes: shifts between pollination systems or divergent use of the same pollinator. Although both are pollinator driven, the mode, relative importance and interdependence of these different processes are rarely studied simultaneously. Here we apply a phylogenetic approach using the Balsaminaceae (including the species-rich genus Impatiens) to simultaneously quantify shifts in pollination syndromes (as inferred from the shape and colour of the perianth), as well as divergent use of the same pollinator (inferred from corolla symmetry). For 282 species we coded pollination syndromes based on associations between floral traits and known pollination systems, and assessed corolla symmetry. The evolution of these traits was reconstructed using parsimony- and model-based approaches, using phylogenetic trees derived from phylogenetic analyses of nuclear ribosomal and plastid DNA sequence data. A total of 71 % of studied species have a bee pollination syndrome, 22 % a bimodal syndrome (Lepidoptera and bees), 3 % a bird pollination syndrome and 5 % a syndrome of autogamy, while 19 % of species have an asymmetrical corolla. Although floral symmetry and pollination syndromes are both evolutionarily labile, the latter shifts more frequently. Shifts in floral symmetry occurred mainly in the direction towards asymmetry, but there was considerable uncertainty in the pattern of shift direction for pollination syndrome. Shifts towards asymmetrical flowers were associated with a bee pollination syndrome. Floral evolution in Impatiens has occurred through both pollination syndrome shifts and divergent use of the same pollinator. Although the former appears more frequent, the latter is likely to be underestimated. Shifts in floral symmetry and pollination syndromes depend on each other but also partly on the region in which these shifts take place, suggesting that the occurrence of pollinator-driven evolution may be determined by the availability of pollinator species at large geographical scales.

Natural parasitism on Anastrepha spp. (Diptera: Tephritidae) over Neotropical region boundaries in northeastern Mexico

ABSTRACT Anastrepha is one of the most species rich-genera of fruit flies in the order Diptera involving pest species of quarantine importance to Mexico. This study aimed to explore and analyze the natural parasitism associated with Anastrepha spp. in a Neotropical transition region from Mexico in the biosphere reserve ‘El Cielo,’ Tamaulipas, Mexico. Anastrepha was represented by Anastrepha fraterculus (Wiedemann), A. ludens Loew, A. obliqua Macquart, and A. zuelaniae. Doryctobracon areolatus (Szépligeti) revealed the highest parasitism rate (77.3%), followed by Trichopria sp. Ashmead (63.6%), Odontosema anastrephae (Borgmeier) (29.5%), Utetes anastrephae Viereck (7.95%), Doryctobracon crawfordi (Viereck) (7.69%), Aganaspis sp. Lin (1.2%)., and Trybliographa nordlanderi (Wharton) (0.7%). Prunus persica and Spondias mombin hosted the highest diversity of parasitoids. Natural parasitism of Do. crawfordi on A. ludens in Citrus sinensis is reported. Trichopria sp. was recorded attacking Anastrepha zuelaniae Stone in Passiflora serratifolia and O. anastrephae parasitising A. fraterculus and A. ludens on P. persica. Results highlight the prevalence of native parasitoids, as well as the biosphere reserve ‘El Cielo’ as the most northern natural reservoir of natural enemies of Anastrepha pest species in the neotropical region.

An update and revision of the Andrena fauna of Morocco (Hymenoptera, Apoidea, Andrenidae) with the description of eleven new North African species.

Morocco has a diverse bee fauna, but one that has also been relatively understudied in recent years. Here a revision of the species-rich genus Andrena is presented that reveals eleven new species for science and substantially improves our understanding of North African Andrena. From Morocco, Andrena (Aciandrena) semiadesus Wood, sp. nov., Andrena (Aciandrena) triangulivalvis Wood sp. nov., Andrena (Campylogaster) sparsipunctata Wood sp. nov., Andrena (Carandrena) hebescens Wood sp. nov., Andrena (Cnemidandrena) niveofacies Wood sp. nov., Andrena (incertae sedis) tenebricorpus Wood sp. nov., Andrena (Notandrena) acutidentis Wood sp. nov., Andrena (Poliandrena) breviceps Wood sp. nov., and Andrena (Poliandrena) farinosoides Wood sp. nov. are described and their ecology is discussed. Andrena (Aciandrena) astrella Warncke, 1975 is synonymised with Andrena (Aciandrena) fulica Warncke, 1974 syn. nov. The unknown female of Andrena (Nobandrena) ounifa Warncke, 1974, and the unknown male of Andrena (Poliandrena) guichardi Warncke, 1980 are described. Andrena (incertae sedis) gafsensis Wood sp. nov. from Tunisia is described due to its similarity to Andrena tenebricorpus. Andrena (Poecilandrena) nigriclypeus Wood sp. nov. from Algeria is also described as it was collected within 10 km of the Moroccan border. A further 18 species are recorded in Morocco for the first time. Andrena (Melandrena) nitida (Müller, 1776) and Andrena (Notandrena) nitidiuscula Schenck, 1853 are removed from the Moroccan list due to historic problems in the application of these names to Mediterranean taxa.
