Delimitation of Ophioderma teres (Lyman, 1860) and Ophioderma unicolor H.L. Clark, 1940 stat. nov. (Echinodermata: Ophiuroidea), including the description of two new species

Ophioderma teres (Lyman, 1860), an ophiuroid previously believed to have a wide distribution in the eastern Pacific, has been found to have an unclear taxonomic identity. While considered a well-known species, recent studies have revealed that O. teres lacks a holotype and has vague boundaries with its congeners Ophioderma teres unicolor H.L. Clark, 1940 and Ophioderma sodipallaresi Caso, 1986, as well as with two additional new morphotypes detected in Mexico and Nicaragua, causing continuous misidentifications. This study utilized an integrative taxonomy approach based on morphologic, morphometric, and molecular evidence to clarify the taxonomic status of O. teres, O. sodipallaresi, O. teres unicolor, and the two new morphotypes. Data integration led to the following results: 1) the neotype designation and redescription of O. teres; 2) the proposal of O. sodipallaresi as a junior synonym of O. teres; 3) the status change of O. unicolor stat. nov. from subspecies to species, and 4) the description of the morphotypes as the new species Ophioderma aija sp. nov. and Ophioderma bichi sp. nov. An identification key to the eastern Pacific species of Ophioderma was also developed. This work contributes to the knowledge of Ophioderma in the region, increasing the number of described species and providing resources for their accurate identification.

The Lasiocampidae (Lepidoptera: Lasiocampoidea) of Maputo Special Reserve, Mozambique: a provisional checklist with descriptions of three new species and taxonomic notes

A preliminary checklist of 39 species of lappet moths (Lasiocampidae) is provided for Maputo Special Reserve in southern Mozambique of which three are new to science, Diapalpus smithi sp. n., Eutricha giustii sp. n. and Rhinobombyx maputoensis sp. n., and a further ten are new country records. Several taxonomic changes are implemented in this paper: the synonymy of Sena prompta plusioides (Walker, 1862) syn. rev. with Sena prompta (Walker, 1855) is revived, Bombycopsis (Bufoidia) pallida Joannou & Krüger, 2009 syn. n. is synonymised with B. (B.) nigrovittata Aurivillius, 1927, and Lebeda mustelina Distant, 1899 is transferred to Leipoxais Holland, 1893 comb. n. Additionally, it is shown that the neotype designation by Zolotuhin & Gurkovich (2009) for Lebeda morosa Walker, 1865 is invalid although a new neotype is not selected as the original type may still be extant. All species, forms and both sexes where present are figured, as are the genitalia in the case of the new species and the comparative material examined.

Integrative approach revealing a species complex in the Neotropical freshwater crab Dilocarcinus septemdentatus (Herbst, 1783) (Decapoda: Trichodactylidae) with a description of a new species

The taxonomic status of the freshwater crab Dilocarcinus septemdentatus (Herbst, 1783) is still not well established. Currently, the main issue involves synonymization with D. spinifer H. Milne Edwards, 1853, based on a variation of the angulation of the gonopod apex. These species are distributed along rivers and lakes in northern South America, with disjunct occurrences in central-west Brazil and Argentina. Due to these inconsistencies, an integrative approach was performed to elucidate these questions, with morphological (including NanoCT-Scan) and molecular analysis (Maximum Likelihood Trees, Bayesian Inference, Genetics Distance Matrix, and Haplotype Network), based on mitochondrial markers COI and 16S rRNA. Both analysis revealed and supported the existence of a species complex under the name of D. septemdentatus. Based on the results obtained, we propose the revalidation of D. spinifer, the description of a new species, and the redescription of D. septemdentatus s. str., with a neotype designation for this species. The hypothesis that this species complex originated in the Pebas System, an extensive mega wetland system that existed along the lowlands of Western Amazonia from late Oligocene to late Miocene (c. 23–11 mya) is discussed.

Resurrection and redescriptions of nominal species previously regarded as synonyms of Thrissina mystax (Bloch and Schneider, 1801) (Teleostei: Clupeiformes: Engraulidae).

Examination of the original descriptions and available type specimens of nominal species previously regarded as synonyms of Thrissina mystax (Bloch and Schneider, 1801), and many non-type specimens representing an extensive geographic range, confirmed the validities of T. mystax, Thrissina porava (Bleeker, 1849), and Thrissina valenciennesi (Bleeker, 1866). Additionally, Engraulis poorawah Bleeker, 1872, a nominal species previously regarded as a junior synonym of T. mystax, is recognized as a junior synonym of Thrissina malabarica (Bloch, 1795). Diagnoses and detailed color descriptions are given for all of the valid species, in addition to clarification of their taxonomic histories, and neotype designation for T. porava. The phylogenetic relationships among 15 species of Thrissina (including T. porava and T. valenciennesi but not T. mystax) were reconstructed from the mitochondrial cytochrome oxidase I (COI) gene. T. porava and T. valenciennesi were not recovered as a monophyletic group, instead being divergent from each other and the other species of Thrissina by 12.4% and >11.7% mean uncorrected distances, respectively, confirming their reciprocal validity.

Species of the Western Palaearctic Genus Tetralonia Spinola, 1838 (Hymenoptera, Apidae) with Atypical Pollen Hosts, with a Key to the pollinosa-Group, Description of New Species, and Neotype Designation for Apis malvae Rossi, 1790

The long-horn bee genus Tetralonia consists of 35 Western Palaearctic species that are associated mostly with the family Asteraceae as host plants. A minority of the species are, however, exclusively associated with other host plants that have particularly large pollen grains, such as those in the plant families Caprifoliaceae, Malvaceae, and Onagraceae. This work presents a taxonomic account and morphological description of the assemblages of Tetralonia species with atypical (non-Asteraceae) host plants. It includes a key to the pollinosa-group, which contains most of the species, a description of three regionally restricted new species, namely T. eoacinctella Dorchin sp. nov., T. epilobii Dorchin sp. nov., and T. stellipilis Dorchin sp. nov., a lectotype designation for Eucera cinctella Saunders, 1908 [=Tetralonia cinctella (Saunders, 1908)], and a neotype designation for Apis malvae Rossi, 1790 [=Tetralonia malvae (Rossi, 1790)]. In addition, the name Eucera macroglossa Illiger, 1806 is confirmed as a synonym of Apis malvae Rossi, 1790; Tetralonia macroglossa ssp. xanthopyga Alfken, 1936 is officially placed in synonymy with Apis malvae Rossi, 1790; and Macrocera confusa Pérez, 1902 is listed as a doubtful synonym of Tetralonia scabiosae Mocsàry, 1879 (syn. nov.).

Revision of the Late Miocene hornless rhinocerotids from Samos Island (Greece) with the designation of neotypes and implications for the European chilotheres

ABSTRACT Extant rhinoceroses are represented only by five species and are characterized by the presence of a nasal horn. In the past, they were much more diverse, with one of the best-known groups being the aceratheriines, i.e., hornless rhinoceroses. Chilotheres are a group of hornless rhinos that inhabited Eurasia during the Late Miocene. Their westernmost geographic range reached Eastern Europe, where overall eight species have been erected. Four of these were described based on material from the Upper Miocene of Samos Island (Greece), two of which are not considered valid anymore. Unfortunately, the type skulls of all four species are lost and there are several issues concerning their taxonomy. Therefore, we herein designate two skulls housed in historical collections from Samos as neotypes for the first two species, Chilotherium schlosseri (Weber, 1905) and Eochilotherium samium (Weber, 1905), and provide detailed comparisons for the separation of the species from each other and from any other chilotheres. Our results prove that the two species are valid and justify their separation on a generic level. Chilotherium schlosseri seems to be more closely affiliated with the other European Chilotherium species, whereas E. samium is more similar to the Chinese ‘Chilotherium’ wimani and ‘Chilotherium’ primigenium, based on their more plesiomorphic characters.

Taxonomic revision ofIsochelesStimpson, 1858 andLoxopagurusForest, 1964 (Decapoda: Anomura: Diogenidae) using morphological and multigene data, with the description of a new Eastern Pacific species

AbstractThe genera IsochelesStimpson, 1858 and LoxopagurusForest, 1964 are endemic to America and occur in tropical and subtropical waters. There are five species of Isocheles, two of them are found in the Western Atlantic (I. sawayaiForest & de Saint Laurent, 1968 and I. wurdemanniStimpson 1859) and three in the Eastern Pacific (I. pilosus (Holmes, 1900), I. pacificusBouvier, 1907, and I. aequimanus (Dana, 1852)). Loxopagurus is a monotypic genus and occurs only in southeastern South America. These two genera are morphologically similar, with differences in shape and size of chelae. The published information on the taxonomy of these genera is scant, and there have been some recent doubts about their phylogenetic relationship. Our study aimed to elucidate the phylogenetic relationship of Isocheles and Loxopagurus and evaluate their taxonomic validity and contextualization in Diogenidae Ortmann, 1892. We performed an integrative analysis using multigene data (16S rRNA, COI, and H3) and a detailed morphological evaluation, including redescriptions, seeking characters that allow the clear identification of these species. The type specimens of I. aequimanus, I. pilosus, and L. loxochelis (Moreira, 1901) were lost and errors are common regarding the identification of the species of Isocheles. Characters that clearly delimit these species, such as the ornamentation and shape of the chelipeds and the number of teeth on the second article of the antenna, were stated. The morphological and molecular analyses corroborated the taxonomical validity of Isocheles and Loxopagurus as two distinct genera based on the differences of the shield and chelipeds, on the topology of the trees, and on the genetic divergence inferred from three molecular markers. We also verified that the five amplified species of Isocheles constitute five distinct clades and described a new species of Isocheles, using both molecular and morphological differences from congeners. An identification key for Isocheles is proposed. Although the type material of two out of the five species of Isocheles and the holotype of Loxopagurus loxochelis were lost, the designation of neotypes is not recommended in these cases.

New records, neotype designation and DNA sequences of three species of Chaetonotus (Gastrotricha: Chaetonotidae) from Brazil

Gastrotrichs are aquatic microinvertebrates (less than 1 mm long) commonly found in freshwater and marine environments worldwide. The taxonomy of gastrotrichs is mainly based on external morphological characters, such as body shape and size of the different body regions, presence and distribution of adhesive tubules, or the microstructure of the external cuticle (e.g. scales, spines, cephalic plates). The diversity of Gastrotricha is still poorly known, especially in tropical regions. The aim of this study is to use integrative taxonomy to report new records of Chaetonotus dadayi, C. paucisquamatus and C. furcatus from the states of São Paulo and Minas Gerais, Brazil. In this study we present 1) new records of C. dadayi in Brazil with new morphological information and a first-time comprehensive diagnosis of the species; 2) the redescription of C. paucisquamatus based on material collected at the type locality and the neotype designation; and 3) the first record of C. furcatus outside its type locality. We also discuss the actual occurrence of C. paucisquamatus and C. furcatus in Poland, given that both species were found in artificial environments with flora imported from South America.

Integrative taxonomy helps to revise systematics and questions the purported cosmopolitan nature of the type species within the genus Diaforobiotus (Eutardigrada: Richtersiusidae)

Recent advances in tardigrade taxonomy have been greatly enhanced by the redescriptions of the type species for particular taxa or species groups. De novo characterisation of these key taxa now allows to describe tardigrade species diversity with improved precision and at higher rate, increasing the momentum towards resolving the taxonomic impediment in these micro-invertebrates. Since its description, Diaforobiotus islandicus (Richters, 1904) has been reported from many distinct localities around the world. This suggested, perhaps falsely, a cosmopolitan nature of the species. However, potential erroneous assignment of newly found populations to this species could be a result of the very general and superficial original description. In order to properly recognise and name species diversity within the genus, I provide here an integrative redescription of the type species (D. islandicus) with a neotype designation, a description of a new species, Diaforbiotus svalbardicus sp. nov, and dichotomous key for the genus. Both descriptions are based on detailed morphological and morphometric data associated with standard DNA sequences of four genetic markers (18S rRNA, 28S rRNA, ITS-2, and COI). The genus composition and diagnosis amendments of the family Richtersiuside are also discussed. The presented study constitutes a starting point for further systematic studies on the genus Diaforobiotus and new taxa discoveries.

Morphologic analysis and Neotype designation of the Raspthorn sandskate, Psammobatis scobina, from its type locality

The genus Psammobatis is endemic to South America, and three of its species are sympatric along the Chilean coast. Their morphological similarity as well as the lack of type material of P. scobina, has made its taxonomic identification especially complex. The aim of this work is to allow for objective identification and comparisons of P. scobina, providing a new morphological characterization, incorporating both morphometric and meristic features for both sexes, and designating a Neotype. Morphometric and meristic data are presented separately for the Neotype, and for males and females to determine variability between sexes. Although there is overlap between some morphometric features of males and females, there are also some morphometric measures that differed between sexes among specimens of similar sizes, such as disc width, length of posterior pelvic lobe, preoral length, distance between fifth gill slits and distance from cloaca to second dorsal fin. Additionally, Principal Component Analysis and cluster analyses allowed to identify sexual dimorphism in specimens, with the most influential variables related to tail length. There are several unresolved issues regarding the taxonomy of this problematic genus, especially those regarding P. scobina and P. normani, which are sympatric in the southeastern Pacific. In addition to the analysis of skeletal structures and egg cases, an integrative comparative morphometric analysis, based on a recent standardized methodology with the inclusion of both morphological and molecular data, is still needed. The designation of a Neotype for objective comparative purposes, will allow such future study.

A new cryptic species of the pineapple fish genus Monocentris (Family Monocentridae) from the western Pacific Ocean, with redescription of M. japonica (Houttuyn, 1782)

A new pineapple fish is described based on 26 type and 80 non-type specimens collected from Taiwan, Vanuatu, the Solomon Islands, and Queensland, Australia. This new species is sympatric with and similar to Monocentris japonica but can be distinguished from the latter in having only 6 or 7 scales on the third scale row below the lateral line; excisura notched and a small pseudo-excisura present on the sagittal otolith; consistently greater head depth, body depth, postorbital length, dorsal-fin-pelvic-fin length, and dorsal-fin-pectoral-fin length in proportion to standard length. A detailed description and designation of neotype are provided for M. japonica. DNA barcoding analysis supports the distinction of the new species with an estimated average COI gene divergence of 3.6 % from M. japonica.

Solving a running crab spider puzzle: delimiting Cleocnemis Simon, 1886 with implications on the phylogeny and terminology of genital structures of Philodromidae

BackgroundAmong the 16 Neotropical genera of Philodromidae, Cleocnemis has the most troublesome taxonomic situation. Remarkable morphological differences among several genera historically said to be related to Cleocnemis denote controversial notions and general uncertainty about the genus identity. Thus, to clarify the genus limits and contribute to the understanding of Neotropical Philodromidae, we conducted a morphological analysis, along with Bayesian Inference and Maximum Likelihood molecular phylogenetic analyses focusing on Cleocnemis and related genera of Thanatinae. All of the 14 species previously placed in Cleocnemis were studied, and eight of them included in the molecular analyses based on fragments of 28S rDNA, histone H3, 16S rDNA, and cytochrome oxidase I (COI).ResultsCleocnemis was recovered as polyphyletic. Most of its species are distributed into six lineages allocated into five morphologically recognizable groups: Group I [Cleocnemis heteropoda], representing Cleocnemis sensu stricto and two new junior synonyms, Berlandiella and Metacleocnemis; Group II [Tibelloides bryantaecomb. nov., Tibelloides punctulatuscomb. nov., Tibelloides reimoserinom. nov., and Tibelloides taquaraecomb. nov.], representing Tibelloidesgen. rev., which was not recovered as monophyletic; Group III [Fageia moschatacomb. nov., Fageia roseacomb. nov.], representing the genus Fageia; Group IV [“Cleocnemis” lanceolata]; and Group V [“Cleocnemis” mutilata, “Cleocnemis” serrana, and “Cleocnemis” xenotypa]. Species of the latter two groups are considered incertae sedis. Cleocnemis spinosa is maintained in Cleocnemis, but considered a nomen dubium. Cleocnemis nigra is considered both nomen dubium and incertae sedis. We provide a redelimitation of Cleocnemis, redescription, neotype designation, and synonymy of type-species C. heteropoda. Taxonomic notes on composition, diagnosis, and distribution for each cited genus are also provided. Phylogenetic results support the division of Philodromidae into Thanatinae new stat. and Philodrominae new stat. and suggest expansion of their current compositions. Terminology of genital structures of Philodromidae is discussed.ConclusionsOur results bring light to Cleocnemis taxonomy and enhance the understanding of the relationships within Philodromidae, especially through the assessment of neglected Neotropical taxa.

Rhipicephalus linnaei (Audouin, 1826) recognised as the “tropical lineage” of the brown dog tick Rhipicephalus sanguineus sensu lato: Neotype designation, redescription, and establishment of morphological and molecular reference

We re-describe the adult stages of Rhipicephalus linnaei (Audouin, 1826), and characterise its diagnostic molecular traits. A male R. linnaei collected in Esna City, Luxor Governorate, Egypt is designated as the neotype. Rhipicephalus linnaei is re-established as a valid tick name and removed from the synonymy list of Rhipicephalus sanguineus (Latreille, 1806). Rhipicephalus linnaei is most similar to R. sanguineus and Rhipicephalus camicasi Morel, Mouchet & Rodhain, 1976 because they share similar elongated comma-like spiracula that are narrowly visible dorsally, and the dorsal prolongation is narrower than the width of the adjacent festoon. The male of R. camicasi is distinguished from R. linnaei by the non-tapering caudal widening of the spiracula. The male of R. sanguineus is distinguished from R. linnaei by shorter extension that does not taper into a long narrow extension of the spiracula. The genital pore atrium of female R. linnaei is broadly U-shaped, while it is a narrower U-shape in R. sanguineus. The remaining species within the R. sanguineus species complex – Rhipicephalus sulcatus Neumann, 1908, Rhipicephalus turanicus Pomerantsev, 1940, Rhipicephalus guilhoni Morel & Vassilades, 1963, Rhipicephalus secundus Feldman-Muhsam, 1952 and Rhipicephalus afranicus Bakkes, 2020, all exhibit spiracula with the dorsal prolongation as wide as the adjacent festoon. The DNA sequence of R. linnaei is most closely related to R. guilhoni. The phylogenetic analysis of mitogenome (mtDNA) sequences including assembled mtDNA from whole genome sequencing of the neotype supports R. linnaei as a well-defined taxon when compared with DNA sequences of other species of the R. sanguineus species complex, in particular: R. sanguineus, R. turanicus, R. secundus and R. camicasi. Molecularly, R. linnaei belongs to the so-called R. sanguineus s.l. "tropical lineage" distributed globally including the Americas, Africa, Europe, Asia and is the only species from R. sanguineus species complex in Australia.

A key to species of Hercinothrips, with one new species, and a neotype designation for H. trilineatus (Priesner).

A female neotype from Transvaal, South Africa, is designated for Hercothrips trilineatus Priesner, the original type specimens from Tanzania having been destroyed in Hamburg during the 1940s. Hercinothrips splendens sp.n. is described from both sexes taken from Aloe plants in a Netherlands greenhouse. A key is provided to the 10 known extant species of Hercinothrips.

Taxonomic study on Sinopoda Jäger, 1999 (Araneae, Sparassidae, Heteropodinae), with three new species from Korea.

The genus Sinopoda Jäger, 1999 is a group of huntsman spiders (Araneae: Sparassidae: Heteropodinae), and currently seven species have been reported in Korea. In this study, three new species are described from Korea, Sinopodabigibba sp. nov., Sinopodabogil sp. nov., and Sinopodapantherina sp. nov.; Sinopodajirisanensis Kim & Chae, 2013 is revalidated with neotype designation, and had been formerly synonymized with Sinopodaforcipata (Karsch, 1881). Additionally, all previous records of Sinopodastellatops Jäger & Ono, 2002 and S.forcipata from Korea are deemed misidentifications of S.jirisanensis and S.bogil sp. nov., respectively.

The taxonomic and nomenclatural status of the nomina Salamandra fusca Green, 1818 and Salamandra quadramaculata Holbrook, 1840 (Amphibia, Urodela)

We address here a few nomenclatural problems concerning some salamander nomina of the plethodontid genus Desmognathus Baird, 1850: the identification of the scriptores (first users) of aponyms (subsequent spellings) in cases of primary homonymy; the validity of airesies (first reviser actions) in special cases; and the validity of neotype designations. Accordingly, we validate Pyron & Beamer’s (2020) invalid designation of a neotype for Salamandra nigra Green, 1818, and we provide a synonymic and aponymic list for Desmognathus fuscus (Green, 1818).

Insight into the cryptic diversity and phylogeography of the peculiar fried egg jellyfish Phacellophora (Cnidaria, Scyphozoa, Ulmaridae).

The fried egg jellyfish Phacellophora camtschatica (senso lato) is a morphologically peculiar and conspicuous species occurring mostly in the cold waters of the North Pacific. It is less common in the cold waters of the NW Atlantic, and occasionally has been reported in the Mediterranean, Arctic, East and South Pacific, and E, SW and NE Atlantic. However, sightings of this scyphozoan jellyfish have intensified during the past two to three decades in Macaronesia, the Iberian Peninsula and the Mediterranean. These jellyfish are known to be voracious predators of other jellies, but also of other taxa, including fish of commercial interest. Therefore, Phacellophora aggregations may threaten local fisheries, aquaculture, and local biodiversity structuring. We report the first known occurrences of Phacellophora in the Azores Islands, which apparently become more frequent in recent years of the past decade. We confirm, through DNA barcoding of COI and 16S mitochondrial markers, the genetic identity of Phacellophora occurring in the Azores (NE Atlantic). We reveal, with COI sequence data, three (potentially four) cryptic species within the Phacellophora camtschatica complex. Two Phacellophora species co-occur in the North Pacific. In the North Atlantic (and possibly in the Mediterranean) one or two distinct species exist. Three nominal species of the genus that are currently synonymized, with type localities in the N Pacific, NW Atlantic, and the Mediterranean, need reassessment. The morphotypes previously defined for the four putative species names given for Phacellophora might be eventually differentiated by the number and disposition of the marginal lappets of umbrellae. This morphologic character has to be further inspected in vouchers of the four genetic lineages of Phacellophora, to decide between the description of new species, and the resurrection of junior synonyms through the designation of neotypes with DNA Barcodes, to validate the identity of the cryptic taxa detected. More haplotype sampling is necessary across the distribution of the genus to further investigate the genetic diversity and phylogeographic history of Phacellophora. The high genetic relatedness of Phacellophora from the cold NW Atlantic and the sub-tropical shores of the Azores, revealed by 16S and COI sequence data, suggests a recent invasion, in terms of geologic time, of the temperate waters of the NE Atlantic (and possibly of the Mediterranean). The medusivorous habits of Phacellophora, and especially its predation on the mauve stinger (Pelagia spp.) which frequently blooms in Macaronesia and Mediterranean waters, could relate to the recent reports of Phacellophora in the Azores, Madeira, Canary Islands, and the Mediterranean.More investment, including on scientific staff, is necessary to catalog, DNA barcode and monitor jellyfish dynamics more accurately worldwide.

Additional comments on the types and nomina of several North American ratsnakes (Pantherophis obsoletus complex, Colubridae, Serpentes)

Here, we provide updates to our recent paper reviewing the taxonomy and nomenclature of the Eastern ratsnakes (Pantherophis obsoletus complex, Colubridae, Serpentes). Specifically, we clarify that Coluber alleghaniensis Holbrook, 1836 is a subjective, rather than objective, senior synonym of Elaphis holbrookii Duméril, Bibron & Duméril, 1854. Contrary to our statement that USNM 1733–4 were syntypes of Scotophis lindheimerii Baird & Girard, 1853, the former is the holotype and the latter is the paratype. The holotype is lost and the paratype is in poor condition, but no neotype designation is warranted at present. We note that USNM 248870, which we designated as the lectotype of Coluber obsoletus lemniscatus Cope, 1888, was originally cataloged as USNM 4710. This catalog number was shared with the type of the salamander Amblystoma tenebrosum Baird & Girard, 1852, and the snake was re-cataloged as USNM 248870 in 1985. Finally, we originally treated C. reticulatus La Cépède, 1789 and C. reticularis Daudin, 1803 as senior subjective synonyms of C. corais Boie, 1827, but here corroborate recent authors in designating it a senior subjective synonym of C. obsoletus Say in James, 1823. As the Commission suppressed C. reticulatus La Cépède, 1789 (an exoplonym), this subsequently rendered C. reticularis Daudin, 1803 (an exoploneonym) unavailable as well.
