molecular identification of western european species of obsoletus complex diptera Ceratopogonidae by an internal transcribed spacer 1 rdna multiplex polymerase chain reaction assay
Journal of Medical Entomology, 2007Co-Authors: Bruno Mathieu, Thierry Baldet, Jeanclaude Delecolle, Aurelie Perrin, Emmanuel Albina, Catherine CetresossahAbstract:Abstract In southern Europe, orbiviral diseases such as bluetongue (BT) have been assumed to have been largely transmitted by the classical Afro-Asian vector Culicoides imicola Kieffer (Diptera: Ceratopogonidae). Recent outbreaks have occurred in regions where C. imicola is normally absent, supporting the theory that other species belonging to the Obsoletus or Pulicaris complexes may play a role in BT virus transmission. Investigations of the ecology of the species within the former group are hampered by females of member species being extremely difficult to separate by classical morphology. To allow straightforward separation of these species in France, a multiplex polymerase chain reaction-based on internal transcribed spacer (ITS)-1 rDNA was developed to distinguish between Culicoides chiopterus Meigen, Culicoides dewulfi Goetghebuer, Culicoides montanus Shakirjanova, Culicoides obsoletus Meigen, and Culicoides scoticus Downes & Kettle. This tool will be useful in defining both the vector role and larv...

Towards the PCR-based identification of Palaearctic [i]Culicoides[/i] biting midges (Diptera: Ceratopogonidae): results from an international ring trial targeting four species of the subgenus [i]Avaritia[/i]
Parasites and Vectors, 2014Co-Authors: Claire Garros, Simon Carpenter, Jeanclaude Delecolle, Nick Golding, Thomas Balenghien, Rudy Meiswinkel, Aurélie Pedarrieu, Ignace Rakotoarivony, Laetitia Gardes, James BarberAbstract:Background: Biting midges of the genus Culicoides (Diptera: Ceratopogonidae) are biological vectors of internationally important arboviruses. To understand the role of Culicoides in the transmission of these viruses, it is essential to correctly identify the species involved. Within the western Palaearctic region, the main suspected vector species, C. obsoletus, C. scoticus, C. dewulfi and C. chiopterus, have similar wing patterns, which makes it difficult to separate and identify them correctly. Methods: In this study, designed as an inter-laboratory ring trial with twelve partners from Europe and North Africa, we assess four PCR-based assays which are used routinely to differentiate the four species of Culicoides listed above. The assays based on mitochondrial or ribosomal DNA or microarray hybridisation were tested using aliquots of Culicoides DNA (extracted using commercial kits), crude lysates of ground specimens and whole Culicoides (265 individuals), and non-Culicoides Ceratopogonidae (13 individuals) collected from across Europe. Results: A total of 800 molecular assays were implemented. The in-house assays functioned effectively, although specificity and sensitivity varied according to the molecular marker and DNA extraction method used. The Obsoletus group specificity was overall high (95-99%) while the sensitivity varied greatly (59.6-100%). DNA extraction methods impacted the sensitivity of the assays as well as the type of sample used as template for the DNA extraction. Conclusions: The results are discussed in terms of current use of species diagnostic assays and the future development of molecular tools for the rapid differentiation of cryptic Culicoides species.

catalog of the biting midges of the world diptera Ceratopogonidae
Zootaxa, 2020Co-Authors: Art Borkent, Patrycja DominiakAbstract:A list of all valid 6,206 extant and 296 fossil species of Ceratopogonidae described worldwide is provided, along with all their synonyms. A full citation and the country of origin of the type is given, with some larger countries also providing a more specific state or province. For the first time, worldwide, nomina dubia are identified. Numbers of species of each genus and subgenus are listed. Within subfamilies and tribes, genera are listed alphabetically. Five species have newly recognized authors, four have new names and 28 new combinations are recognized, with these listed in a table. A commentary on the state of the systematics in the family and particularly of Culicoides Latreille is given. The museums of the world are listed with the types of various authors of Ceratopogonidae species indicated. Authors providing regional catalogs, as well as summation of various collections are tabulated. The rate of description since 1758 indicates a steady progression of description, with, for example, 1,231 valid species described since the compilation of the world species by Borkent Wirth (1997), till the end of 2018. The diversity in each Region is compared and the numbers of species shared between adjacent Regions presented.

the pupae of the biting midges of the world diptera Ceratopogonidae with a generic key and analysis of the phylogenetic relationships between genera
Zootaxa, 2014Co-Authors: Art BorkentAbstract:The pupae of species in each of the 45 genera of Ceratopogonidae known in this stage are diagnosed and described. A standard set of terms is provided, with a glossary, for all pertinent structures of the pupal stage within a context of other Culicomorpha. The variety of terms provided by previous autho rs are synonymized. Some pupal structures are directly related to developing adult structures and these are discussed. A key to the genera (and to the subgenera of Forcipomyia Meigen) allows for their identification. Pupation and pupal behaviour is summarized. A table of all previous descriptions of each stage of the immatures (egg, larva, pupa) is provided, showing that 13% of all validly named extant Ceratopogonidae are known as pupae. This study examined 45% of these species. All species known as fossil pupae are discussed. A phylogenetic analysis based primarily on pupal characters confirms the relationships between the subfamilies as well as the relationships between the genera in Leptoconopinae, Forcipomyiinae and Dasyheleinae. The question of the monophyly of the Culicoidini remains unresolved. Results confirm the paraphyly of the Ceratopogonini and, for the first time, the Sphaeromiini sensu lato , which is divided into Hebetulini (new tribe), Johannsenomyiini Crampton (new status) and Sphaeromiini sensu novum . Sphaeromiini sensu novum includes Sphaeromias Curtis, Leehelea Debenham, Homohelea Kieffer and Xenohelea Kieffer and forms the sister group of the Palpomyiini. Other genera in Sphaeromiini sensu lato not known as pupae are discussed. The genus Mallochohelea Wirth is shown to be polyphyletic and one group of species is therefore recognized as members of the new genus Anebomyia (type species = Mallochohelea atripes Wirth). A number of species previously placed in Stilobezzia Kieffer are sh own to belong to Schizonyxhelea Clastrier. Study of the type species of the monotypic genus Nemoromyia Liu and Yu showed it to be a member of the Palpomyia distincta species group and the generic name is therefore a new junior synonym of Palpomyia. Examination of pupae showed that the following species were misplaced and are now in other genera as follows: Schizonyxhelea brevicostalis (Das Gupta & Wirth), 1968: 28 ( Stilobezzia ) new combination, Schizonyxhelea bulla (Thomsen), 1935: 289 ( Stilobezzia ) new combination, S chizonyxhelea cari be (Lane & Forattini), 1958: 208 ( Stilobezzia ) new combination, Schizonyxhelea diminuta (Lane & Forattini), 1958: 209 ( Stilobezzia ) new combination, Schizonyxhelea obscura (Lane & Forattini), 1958: 216 ( Stilobezzia ) new combination, Schizonyxhelea panamensis (Lane & Forattini), 1958: 218 ( Stilobezzia ) new combination, Schizonyxhelea thomsenae (Wirth), 1953: 83 ( Stilobezzia ) new combination, Schizonyxhelea scutata (Lane & Forattini), 1961: 92 ( Stilobezzia ) new combination, Pellucidomyia geari (de Meillon & Wirth), 1981: 547 ( Macropeza ) new combination, Dibezzia prominens (Johannsen) 1932: 435 ( Johannsenomyia ) new combination, Nilobezzia theileri (de Meillon & Wirth, 1981:552) ( Sphaeromias ) new combination, Anebomyia atripes (Wirth, 1962: 281) ( Mallochohelea ) new combination, Anebomyia fluminea (de Meillon & Wirth), 1981: 550 ( Mallochohelea ) new combination, Anebomyia siricis (de Meillon), 1961: 50 ( Sphaeromias ) new combination, Anebomyia texensis (Wirth), 1962: 283 ( Mallochohelea ) new combination, Anebomyia yunnana (Yu & Zou), in Yu et al. 2005: 1503 ( Mallochohelea ) new combination, Bezzia goezii (Schrank), 1803: 72 ( Tipula ) new combination (also a nomen nudum ), Palpomyia nemorosa (Liu & Yu), 1991: 26 ( Nemoromyia ) new combination. Bezzia xanthogaster (Kieffer), 1919: 130 ( Probezzia ) is a junior homonym of Probezzia xanthogaster (Kieffer), 1917: 329 ( Bezzia ) and is here given the new name Bezzia gilvigaster Borkent. The fossil genus Paraculicoides Pierce, 1966: 94 and its type species Paraculicoides rouseae Pierce, 1966: 94 are removed from the Ceratopogonidae and likely belong in the Psychodidae.

global diversity of dipteran families insecta diptera in freshwater excluding simulidae culicidae chironomidae tipulidae and tabanidae
Hydrobiologia, 2008Co-Authors: Rudiger Wagner, Art Borkent, Miroslav Bartak, Gregory W Courtney, Boudewijn Goddeeris, Jeanpaul Haenni, Lloyd Knutson, Adrian C Pont, Graham E Rotheray, Rudolf RozkošnýAbstract:Today’s knowledge of worldwide species diversity of 19 families of aquatic Diptera in Continental Waters is presented. Nevertheless, we have to face for certain in most groups a restricted knowledge about distribution, ecology and systematic, particularly in the tropical environments. At the same time we realize a dramatically decline or even lack of specialists being able, having the time or the opportunity to extend or even secure the present information. The respective families with approximate numbers of aquatic species are: Blephariceridae (308), Deuterophlebiidae (14), Nyphomyiidae (7), Psychodidae (∼2.000), Scatopsidae (∼5), Tanyderidae (41), Ptychopteridae (69), Dixidae (173), Corethrellidae (97), Chaoboridae (∼50), Thaumaleidae (∼170), Ceratopogonidae (∼6.000), Stratiomyidae (∼43), Empididae (∼660), Lonchopteridae (2), Syrphidae (∼1.080), Sciomyzidae (∼190), Ephydridae (∼1.500), Muscidae (∼870). Numbers of aquatic species will surely increase with increased ecological and taxonomical efforts.
