Diversity of Calliphoridae and Sarcophagidae (Diptera: Oestroidea) in a forested area in the municipality of Macaé, RJ, Brazil

Sarcophagidae and Calliphoridae are families of Diptera that cover, respectively, about 3,100 and 1,000 species described worldwide. The species of these families have medical and veterinary importance, due to their role as vectors of pathogenic agents. The Diptera fauna is little known in many Brazilian ecosystems, including some phytophysiognomies of the Atlantic Forest. In the present study, two expeditions were carried out, one in the rainy season and the other in the dry season, using four traps baited with fish and exposed for 48 hours in the field in the Parque Natural Municipal Atalaia in the municipality of Macaé. The collected material was sorted and assembled at Instituto de Biodiversidade e Sustentabilidade - NUPEM/UFRJ and transported to Laboratório de Biodiversidade e Sistemática de Diptera - Museu Nacional, UFRJ (MNRJ), for later identification. A total number of 712 specimens of Calliphoridae and 27 of Sarcophagidae were collected. The sampling effort for Sarcophagidae collection was average, since the species accumulation curve continues to rise, unlike the Calliphoridae curve, which remains stable. The study included species considered asynanthropic, as Hemilucilia semidiaphana (Rondani, 1850) (Calliphoridae), but also invasive species, like those of the genus Chrysomya Robineau-Desvoidy, 1830 (Calliphoridae). Therefore, the present study contributed to expand knowledge about both families in the Atlantic Forest, in Rio de Janeiro, and emphasized the importance of continuing studies in the region, as many species are asynanthropic, while others are invasive, which can result in the inhibition of the native ones.

One new species of Imitomyia Townsend and five newly recorded species of Dexiinae (Diptera: Tachinidae) from China.

During our study of the Chinese Fauna of Diptera, many specimens from the subfamily Dexiinae were examined. One new species was recognized, Imitomyia wangi sp. nov. Additionally, five species, Actinochaetopteryx patellipalpis Richter, Chetoptilia puella (Rondani), Leptothelaira longicaudata Mesnil & Shima, Phyllomya takanoi Mesnil and Rutilia (Chrysorutilia) rubriceps Macquart, are newly recorded in China. Their descriptions, illustration and diagnoses are given.

Sarcophagidae (Insecta: Diptera) of Saudi Arabia: new records, an updated checklist and a new species.

As part of a study on the biodiversity of Diptera of south-western Saudi Arabia, a survey of the Diptera fauna of Jazan, Asir and Najran at 10 sites was performed between 20122015 mainly using Malaise traps, sweep nets and baited traps. A total of 21 species of Sarcophagidae are recorded and documented with photographs, seven of which represent new country records for Saudi Arabia. Including species with a reliable previous record from Saudi Arabia, the total number of species of Sarcophagidae known from Saudi Arabia now stands at 51. All species of Sarcophagidae recorded from Saudi Arabia are listed, including distributions and the source where species were first recorded. Material studied as part of the project resulted in 16 new country records for other countries. Alusomyia Villeneuve, 1933 is here synonymized with Hoplacephala Macquart, 1834, syn. nov., argued from the presence of four proclinate orbital bristles, the row of strong parafacial setae close to the anteroventral eye-margin, the large gena and the robust habitus compared to most other miltogrammines. The generic synonomy requires the new combinations Hoplacephala transfuga (Villeneuve, 1933), comb. nov. and Hoplacephala turana (Rohdendorf, 1975), comb. nov. Sarcophaga surcoufi Villeneuve, 1913 is synonymized with Engelisca adhamae Lehrer & Abou-Zied, 2008, syn. nov. An appendix authored by Dr J.C. Deeming contains the description of Sarcophaga dawahi Deeming, sp. nov.

New records of immature aquatic Diptera from the Foulden Maar Fossil-Lagerstätte, New Zealand, and their biogeographic implications.

The biogeographical and ecological history of true flies (Diptera) in New Zealand is little known due to a scarcity of fossil specimens. Here, we report a fauna of immature aquatic dipterans from freshwater diatomites of the early Miocene Foulden Maar Fossil-Lagerstätte in southern New Zealand. We document 30 specimens of immature dipterans, mostly pupae, and compare their external morphology to extant aquatic Diptera. Based on the reconstructed paleoenvironment of Foulden Maar, we discuss taxonomic, ecological and taphonomic implications of this early Miocene fauna. Among Chironomidae, one pupal morphotype is attributed to Tanypodinae, one pupal morphotype and one larval morphotype are placed into Chironomus (Chironominae) and a further morphotype into Chironominae incertae sedis. Chaoboridae are represented by a pupal morphotype congeneric or very close to the extant Chaoborus, today globally distributed except for New Zealand. Additional immature specimens are likely larvae and puparia of brachyceran flies but cannot be identified to a narrower range. These finds document an aquatic dipteran fauna in New Zealand in the earliest Miocene and highlight Neogene extinction as a factor in shaping the extant Diptera fauna in New Zealand. Immature aquatic dipterans were a common and likely ecologically important component of the early Miocene Foulden Maar lake. Preservation of larvae and pupae may have been promoted by diatomaceous microbial mats and the light colour of the diatomite likely facilitated spotting of these minute fossils in the field.

An annotated checklist of the Diptera of the Galápagos Archipelago (Ecuador).

The Diptera fauna of the Galápagos Archipelago is updated and an annotated checklist is presented. Currently 50 families, 207 genera, and a minimum of 324 species are recorded from the islands. Approximately 107 species are considered to have arrived on the Galápagos Islands through human introductions, an estimated 101 species are considered endemic, 42 species have naturally colonized the islands from mainland Americas, 21 species are either introduced or arrived naturally and 53 species remain unidentified. The following new combination is proposed: Chrysanthrax primitivus (Walker) is moved to Hemipenthes Loew as H. primitivus (Walker) comb. nov. All references to the Galápagos taxonomic literature are included, known island species distributions listed and general remarks on the biology of many species are provided.

Diptera species, new for the Republic of Mordovia, Russia

The nature conservation depends on the completeness of the knowledge about the biodiversity in the study area. Today, data on distribution and diversity of Diptera taxa remain fragmentary. This paper supplements data on the diversity of Diptera species in Europe, Russia, and the Republic of Mordovia. We have studied 1321 specimens of 241 species collected in 2013–2022. Among them, there are species, which are new for Russia (Neoempheria brevilineata, Desmometopa discipalpis) and for both Russia and Europe (Nepphyllomyza flavescensis, Phyllomyza auriculatusa, P. luteipalpis, P. orbita, P. piceus, P. striolatum). We have found for the first time 231 Diptera species for the fauna of the Republic of Mordovia; the families of Bolitophilidae, Keroplatidae, Scatopsidae, Platypezidae, Micropezidae, Opomyzidae, Asteiidae, and Milichiidae have been found for the first time in this region. Anthrax incomptus (Bombyliidae), being previously reported for the Republic of Mordovia, has been excluded now from the fauna of this region. Nine Diptera species have been previously indicated for the Republic of Mordovia without reliable confirmation by collected specimens. In this study, we have confirmed their presence in the Republic of Mordovia. Taking into account the results of the present paper, the Diptera fauna of the Republic of Mordovia includes currently 1187 species belonging to 71 families. Data on collecting methods have been presented for the found species. We provide a comparison of collecting methods and suggestions for an effective inventory of the regional Diptera fauna. We are of the view that the number of the used collecting methods affects positively the results of the fauna inventory.

A Survey on Native and Invasive Mosquitoes and Other Biting Dipterans in Northern Spain.

Haematophagous Diptera, such as mosquitoes (Culicidae), biting midges (Ceratopogonidae), and black flies (Simuliidae), are important insects for public and animal health due to their capacity to bite and transmit pathogens. Outdoor recreation areas are usually affected by biting species and provide suitable habitats to both adult and immature stages. This study aimed to determine the species diversity and larval sites of these Diptera groups in two golf courses. A multi-method collection approach using ultraviolet-CDC traps, human landing catches, collection in breeding sites, and ovitraps was implemented during summer 2020 in northern Spain. Insects were determined by morphological features accompanied by DNA barcoding. A total of ten native mosquito species were recorded either as adults or as larval stages. The invasive species Aedes japonicus was collected only at egg or pupa stage in ovitraps. Culex pipiens s.l. and Culex torrentium were both common mosquito species accounting for 47.9% of the total larval site collections and their larvae might be found in a wide range of natural and artificial sites. Culiseta longiareolata specimens were also prominent (30.1% of the total) and occurred exclusively in man-made water-filled containers. A total of 13 Culicoides species were identified, 10 of which were captured by ultraviolet-CDC traps, particularly members of the Obsoletus complex (Culicoides obsoletus/Culicoides scoticus, 74.9%) and seven species by emergence traps, being the two most abundant C. kibunensis (44.8%) and C. festivipennis (34.9%). Simulium cryophilum was also collected hovering around the operator under field sampling. A comprehensive representation of the blood-sucking Diptera fauna and their larval sites was obtained by the multi-method approach in two Spanish golf courses.

Coastal Diptera species and communities and their geographic distribution in Aotearoa|New Zealand

ABSTRACT The coast provides an important habitat for insects throughout the world. Some insect taxa are entirely dependent on this continuous but narrow strip of habitat between the land and sea, despite the challenging environmental conditions. In Aotearoa|New Zealand (hereafter Aotearoa), the coastal environment is extensive and varies enormously. Aotearoa is also home to a diverse and predominantly endemic Diptera fauna of roughly 5500 species, and a small but significant proportion of these are found along the coast. Here we provide the first extensive survey of Aotearoa’s coastal flies, and describe how the diversity, richness, and abundance of specialised wrack-inhabiting communities vary. Overall, we recorded 257 different species collected from 109 sites from around Aotearoa’s three main islands, with highest abundance, species richness and diversity all found at South Island sites. Our surveys are estimated to have captured over 80% of the species occupying the seashore, and 100% of the wrack specialist community, for which we identified a country-wide baseline community. This study has provided new and interesting insights into the distribution and diversity of flies in Aotearoa. It also highlights the importance of carrying out broad community surveys to capture and improve our understanding of our local fauna.

New and interesting records of Diptera on glacial sand deposits in Silesia (NE Czech Republic). Part 3 – Acalyptratae 2

Abstract Additional records of 28 species of interest belonging to acalyptrate families Lonchaeidae (1 species), Lauxaniidae (2 species), Chamaemyiidae (9 species), Agromyzidae (16 species) and Opomyzidae (1 species) from glacial sand deposits in the Czech Silesia (NE Czech Republic) are presented and their association with sandy habitats discussed. A total of 25 species are recorded from the Czech Silesia for the first time, 15 are new additions to the fauna of Moravia of which 11 are also new for the whole of the Czech Republic. Six species (Lauxaniidae 1, Agromyzidae 5) are new additions to the Diptera fauna of Poland. Leucopis cerasiphila Gomolitzkaja & Tanasijtshuk, 1986 is recorded for the first time from Europe. None of the here reported species is classified as psammobiont but 8 species are considered psammophilous or probably psammophilous, viz. Minettia longiseta (Loew, 1847) (Lauxaniidae), Leucopis kaszabi Tanasijtshuk, 1970 (Chamaemyiidae), Cerodontha (Xenophytomyza) leptophallus Papp, 2016, Hexomyza sarothamni (Hendel, 1923), Liriomyza dracunculi Hering, 1932, L. latigenis (Hendel, 1920), L. yasumatsui Sasakawa, 1972 (Agromyzidae) and Geomyza subnigra Drake, 1992 (Opomyzidae). The conspicuous species diversity of Chamaemyiidae in Silesian glacial sand deposits is discussed.

Yeşilırmak Nehri’ndeki Sucul Diptera (Insecta) larvalarının dağılımı ve ekolojik özellikleri

Yeşilırmak River is one of the most important running waters of Turkey, but the water quality of this river has been affected by agricultural and domestic pollution. Dams and hydroelectric power plants also threaten the habitat quality and biodiversity of the river. This research contains investigation of Diptera fauna in Yeşilırmak River and tributaries, determination ecological characteristics of the collecting sites according to System A and System B Classification of Water Framework Directive (WFD), assessment of water quality of the studied sites by measuring the physicochemical variables (water temperature, pH, electrical conductivity, dissolved oxygen, NO2-N, NO3-N, NH4-N, PO4-P) and using some metrics (abundance, number of taxa, Simpson Diversity Index, Shannon-Wiener Diversity Index, Margalef Diversity Index, Evenness). Thirty-three (33) sites were sampled from Yeşilırmak River and its tributaries in June 2010. Diptera individuals were detected in 20 of them. Two thousand four hundred forty-five (2445) individuals belonging to 12 families and 16 taxa were identified in 20 sampling sites. The water quality classes of the studied sites were Class III (moderate pollution) and Class IV (heavily pollution) according to values of physicochemical variables.

Aquatic flies (Diptera) in phytotelmata of Neotropical Zingiberales plants

ABSTRACT Phytotelmata are temporary pools of rainwater impounded on plants. These pools provide aquatic habitats in which immature stages of insects live. Zingiberales plants can have two types of phytotelmata, the bract pool on the inflorescence and the tubes formed as young leaves unroll. The Diptera fauna of these habitats are poorly known. This study reports on a systematic inventory of invertebrate communities from Zingiberales in Costa Rica and Peru. Collections of invertebrates were extracted from 251 phytotelmata representing six species of Zingiberales – Heliconiaceae: Heliconia robusta Pax, Heliconia stricta Huber, and Heliconia tortuosa Griggs; Marantaceae: Calathea lutea Schult; and Zingiberaceae: Alpinia purpurata (Vieillard) K. Schumann and Renealmia spp. Aquatic Diptera (620 larvae and pupae) were found in 34 samples (32 bract pools and 2 leaf rolls). These Diptera were extracted, sorted and identified to 22 morpho species in 5 families of aquatic ‘Nematocera’, two families of aquatic Brachycera, and one group of undetermined aquatic Brachycera families. Chironomidae (159 individuals, 3 species) were the numerically dominant family, then Syrphidae (141 individuals, 3 species), and Psychodidae (81 individuals, 2 species). The Peru phytotelmata contained more species of Diptera than the Costa Rica phytotelmata. Altogether, four new host associations are documented between aquatic Diptera and Zingiberales phytotelmata habitats in Costa Rica and 14 such records in Peru. Results of a cluster analysis indicate that communities of aquatic Diptera varied between sampling sites and within and between plants. Phytotelmata add to habitat heterogeneity and are likely to increase diversity of aquatic Diptera and other taxa; therefore, phytotelmata should be included in assessments of aquatic Diptera.

The Muscidae (Diptera) of Saudi Arabia, descriptions of two new species, new records and updated list of species.

Despite the economic and medical importance of many species of Muscidae knowledge of species occurring in Saudi Arabia is insufficient. As part of a study on the biodiversity of Diptera of south-western Saudi Arabia a survey of the Diptera fauna of Jazan, Asir and Najran was performed from 2010 to 2015 at 22 sites. Seventy one known taxa of Muscidae were identified and recorded, 29 of which were recorded for the first time from south-western Saudi Arabia and two new species; Atherigona (Acritochaeta) afrotropicalis Deeming sp. nov. and Helina ponti Deeming sp. nov. are here described. Thus, the total number of Muscidae species that has been recorded from Saudi Arabia (including previous records of 31 species) is 102 and two subspecies. A list of all species and subspecies of Muscidae recorded from Saudi Arabia is provided. The species of Muscidae listed are predominantly of Afrotropical distribution as compared to other regions. Images of 78 taxa are presented. In addition to the results of the identifications all available literature about Muscidae of Saudi Arabia is summarized. Biological information (where known) on the species recorded in this study and the Middle East distribution are included. By developing a research collection and a checklist of species of Muscidae we hope to provide the basis for systematic studies and biogeographical and faunistic analyses, and the necessary guidelines for management of these important flies. The need for further field and laboratory work and surveillance surveys is highlighted.

An overview of the Chloropidae (Diptera) of Saudi Arabia.

Chloropidae are of major economic importance, since the larvae of some species are pests of cereals and grasses, some are parasitoids and predators, and adults of some Hippelates spp. visit and transmit or are suspected of transmitting yaws sores in man and animals and by feeding around the eyes are vectors of Brazilian Purpuric Fever. Within the framework of the exploration of the biodiversity of Diptera in Southwest Saudi Arabia a survey of the grass flies fauna in 18 sites in Jazan, Asir, and Najran in south-western Saudi Arabia was performed mainly using Malaise traps and sweep nets from 2010- to 2016. Sixty six species of 43 genera and three subfamilies of Chloropidae were identified and are recorded from Saudi Arabia, 20 of them for the first time and three are described as new species: Elachiptera arabica Deeming sp. n.; Kwarea ismayi Deeming sp.n. and Tricimba turneri Deeming sp.n.. This makes the total number of Chloropidae species in Saudi Arabia 95 (including 29 species previously recorded). Seventy images are presented. The species of Chloropidae listed are predominantly of Afrotropical/ Palaearctic origin. An updated checklist of Chloropidae species of Saudi Arabia is presented.This study adds new records of Chloropidae to the Saudi Arabian Diptera fauna, which will become reference points for research detailing the systematic geographic distribution and for identifying other specimens submitted for identification. Further species will undoubtedly be discovered with more research involving collecting and rearing methods.

The family Dolichopodidae (Diptera) of the Arabian Peninsula: identification key, an updated list of species and new records from Saudi Arabia

ABSTRACT Despite the species richness of Dolichopodidae or long-legged flies world-wide (over 8000 species) and its prominent role as an important and ubiquitous natural enemy of pests in a variety of habitats, only four species have been recorded from Saudi Arabia prior to this study. As part of a study on the biodiversity of Diptera of south-western Saudi Arabia, a survey of the Diptera fauna of Jazan, Abha and Najran was performed from 2012 to 2016 using mainly Malaise traps, sweep nets and light traps. Twenty-one species belonging to seven subfamilies of Dolichopodidae were identified and recorded in this study, 20 species and five subfamilies of these are recorded for the first time from south-western Saudi Arabia. This study increases the total number of dolichopodid species in Saudi Arabia (including previous records) to 25. Twenty-one images are presented. A key to genera and species of the Dolichopodidae of the Arabian Peninsula is provided. A list of all dolichopodid species recorded from Saudi Arabia and the Arabian Peninsula is given. Biological information (if known) and world distribution are included. It seems likely that further species will be discovered with more research involving the use of mass trapping methods. http://www.zoobank.org/urn:lsid:zoobank.org:pub:CA325144-D56F-438A-9E2C-681E89862747

First records of the rare family Clusiidae (Diptera, Opomyzoidea) from Iran

During our research on the Diptera fauna ofnorthern Iranduring 2017–2018, three species of the family Clusiidae have been collected and identified. Clusiaflava(Meigen, 1830), Clusia tigrina (Fallén, 1820) and Clusiodes ruficollis (Meigen, 1830) are recorded fromIran for the first time. These also represent the first records of the family Clusiidae from Iran.

New and interesting records of Diptera on glacial sand deposits in Silesia (NE Czech Republic). Part 1 - Acalyptratae

Abstract Records of 18 species of the families Micropezidae (1 species), Lonchaeidae (1 species), Lauxaniidae (1 species), Chamaemyiidae (6 species), Agromyzidae (6 species) and Chloropidae (3 species) from glacial sand deposits in the Czech Silesia (NE Czech Republic) are presented and their association with sandy habitats is discussed. All of them are recorded from the Czech Silesia for the first time, 4 are new additions to the fauna of Moravia and 9 for the whole Czech Republic. None of the recorded species is psammobiont but five of them are classified as psammophilous, viz. Micropeza lateralis Meigen, 1826 (Micropezidae), Calliopum geniculatum (Fabricius, 1805) (Lauxaniidae), Cerodontha (Xenophytomyza) leptophallus L. Papp, 2016, Ophiomyia disordens Pakalniškis, 1998 (both Agromyzidae), Aphanotrigonum parahastatum Dely-Draskovits, 1981 (Chloropidae), and Leucopis celsa Tanasijtshuk, 1979 as probably psammophilous. A new easternmost record of M. lateralis (from S. Poland: Godów) is presented and the association of this species and C. geniculatum with growths of Cytisus scoparius is confirmed. Leucopis monticola Tanasijtshuk, 1961, L. celsa and A. parahastatum are recorded from northernmost known localities. These species, and also C. (X.) leptophallus seem to be thermophilous and/or xerophilous and can be considered southern elements in the Silesian fauna of Diptera.
