NEW RECORDS OF CHIRONOMIDAE (DIPTERA) FROM CONTINENTAL FRANCE

Abstract Material recently collected in Continental France has allowed me to generate a list of 83 taxa of chironomids, including 37 new records to the fauna of France. According to published data on the chironomid fauna of France 718 chironomid species are hitherto known from the French territories. The nomenclature and taxonomy of the species listed are based on the last version of the Chironomidae data in Fauna Europaea, on recent revisions of genera and other recent publications relevant to taxonomy and nomenclature

Rheocricotopus (s. str.) costai sp. n. and R. (s. str.) pyrenaeus sp. n., two relict species from glacial rheocrenes and streams in corsica and the eastern pyrenees (diptera: chironomidae, orthocladiinae)

Two new species of the genus Rheocricotopus subgenus Rheocricotopus (R. costai sp. n. and R. pyrenaeus sp. n.) are diagnosed and described, based on material collected in some glacial rheocrenes and streams located in the high mountains of Corsica and the Eastern Pyrenees. Rheocricotopus costai sp. n. is described as male and pupal exuviae, while R. pyrenaeus sp. n. is described as male and female adults and pupal exuviae. Rheocricotopus costai sp. n. is known from both western Corsica and the Eastern Pyrenees, while the geographical distribution of R. pyrenaeus sp. n. is restricted to the protected area of the Mantet Nature Reserve (Eastern Pyrenees). Larvae of both R. costai sp. n. and R. pyrenaeus sp. n. are exclusively rheophilic being confined to lotic habitats located at high altitude (crenal and rhithral). Apart from the presence of an additional median circular small patch of spinules on tergite III of the exuviae, R. costai sp. n. directly keys into the effusus-group on the basis of several specific characters found in the male adult. Nevertheless, R. pyrenaeus sp. n. keys near both of R. reduncus Sæther & Schnell, 1988 (known from Finland, Norway and Russian Far East) and R. tchernovskii Makarchenko & Makarchenko, 2005 (known from Russian Far East), based in particular, on the unusual shape of the superior volsella which is inwardly markedly turned over distally. The genus Rheocricotopus is currently represented by 10 species in continental France and by 8 species in Corsica (Moubayed-Breil 2016). Consequently, the description of R. costai sp. n. and R. pyrenaeus sp. n. increases the total number in the genus to 12 for continental France and to 9 for Corsica. Taxonomic remarks, discussion and comments on the ecology and geographical distribution of the two new species are given.Bu çalışmada, Korsika ve Pireneler'deki yüksek dağlarda yer alan glasiyal rheokrenler ve akarsulardan toplanmış materyal incelenmiş ve Rheocricotopus cinsine ait iki yeni tür (R. costai sp. n. and R. pyrenaeus sp. n.) tanımlanmıştır. Rheocricotopus costai sp. n. erkek birey ve pupal kılıf ile tanımlanırken R. pyrenaeus sp. n. yetişkin erkek ve dişi bireyler ve pupal kılıf ile tanımlanmıştır. Rheocricotopus costai sp. n. hem Batı Korsika'dan hem de Pireneler’in doğusundan elde edilirken R. pyrenaeus sp. n.'nın coğrafik dağılımı Doğu Pirenler’de bir koruma alanı olan Mantet doğa koruma alanı ile sınırlıdır. Hem R. costai sp. n. hem de R. pyrenaeus sp. n. larvaları yüksek rakımlardaki lotik habitatlarda sınırlı olduklarından reofilik özelliktedirler. Rheocricotopus costai sp. n., pupal kılıfın 3. tergiti üzerinde medyan alanda yer alan küçük dairesel spinül yamasına ek olarak yetişkin erkeklerdeki çeşitli spesifik karakterleri ile effusus-grubu içinde yer almaktadır. Rheocricotopus pyrenaeus sp. n. ise özellikle distalde içe doğru dönük olan superior volsellanın olağan olmayan şekli bakımından Finlandiya, Norveç ve Uzak Doğu Rusyası'ndan bilinen R. reduncus Sæther & Schnell, 1988 ile Uzak Doğu Rusyası'ndan bilinen R. tchernovskii Makarchenko & Makarchenko, 2005'e benzemektedir. Rheocricotopus cinsi Fransa'da 10, Korsika'da ise 8 tür ile temsil edilmekteydi (Moubayed-Breil 2016). Sonuç olarak, R. costai sp. n. and R. pyrenaeus sp. n.'nın tanımlanması ile cinsin Fransa'daki tür sayısı 12'ye, Korsika'daki tür sayısı ile 9'a çıkmıştır. İki yeni türün ekolojileri ve coğrafik dağılımları ile ilgili taksonomik notlar, görüşler ve değerlendirmeler verilmiştir

Communities of Chironomidae (Diptera) from four ecological zones delimited by the Mediterranean coastal ecosystems of Morocco (Moroccan Rif). Updated list and faunal data from the last two decades

Based on a large material collected during the last two decades in 43 sites covering a wide range of habitats (fresh and brackish water) we delimited four ecological zones, which extend between sea level and high mountain areas located above 1000 m. The four ecological zones are: Zone 1 (Estuarine zone including pools, ponds, lagoons and wet meadows, altitude 0-10 m); Zone 2 (Potamal, alt. 10-350 m); Zone 3 (Lower basin of streams and wadis (alt. 350-1000 m); Zone 4 (Upper basin of streams, wadis, springs and peat bogs, alt. > 1000 m). An updated list of 256 species/taxa belonging to Chironomidae (Diptera) has been established which complements previous data for the chironomid fauna of Morocco. The list includes 72 (28%) new records for the fauna of Morocco, 21 (8%) undescribed species and probably 2 new genera (1 Orthocladiinae and 1 Tanytarsini). Spatial distribution of species by subfamilies is highlighted in the four ecological zones where faunal comparative results are: Buchonomyinae (1 species); Tanypodinae (21); Diamesinae (8); Orthocladiinae (143); Chironominae (82, including 40 Chironomini and 42 Tanytarsini). Currently, a total of 410 valid species are reported from Morocco. The low frequency of both listed and undescribed species in Mediterranean coastal ecosystems is linked to the limited faunal knowledge of wetland coastal areas and fragility of lowland habitats, which are regarded as true hotspots

Cricotopus (s. str.) latellai sp. n., a new rheophilic species of the tremulus-group from the Italian and French Maritime Alps (Diptera: Chironomidae)

Cricotopus (Cricotopus) latellai sp. n. is described and diagnosed based on material comprising male and female pharate adults, pupal exuviae and larvae recently collected in some glacial streams in both the Italian and French Maritime Alps. Taxonomic notes provided in this paper include: description of C. latellai sp. n. as male and female adults, pupal exuviae and last instar larvae. The diagnosis of the Cricotopus tremulus-group is supplemented with additional characters in the male adult and pupal exuviae. Cricotopus latellai sp. n. keys near C. mantetanus Moubayed-Breil, 2016 and C. storozhenkoi Makarchenko & Makarchenko, 2016. Geographical distribution of C. latellai sp. n. is currently restricted to the Italian and French Maritime Alps. It belongs to the Tyrrhenian community of glacial relic species, which are considered to be indicators of climate change in this biogeographical region. Remarks, taxonomic position, and ecology of the new described species are given

On the genus Chaetocladius s. str. Kieffer, 1911 from Switzerland with descriptions of five new relic species occurring in glacial alpine springs and streams (Diptera, Chironomidae)

A description of the male adults of five Chaetocladius s. str. species (C. castellae sp. n., C. lencioniae sp. n., C. lodscrozetae sp. n., C. macunensis sp. n. and C. muttensis sp. n.) is provided based on material collected in some glacial alpine springs and cold streams located in the Swiss Alps (altitude 1800–2700 m). Male adult of the nearest Chaetocladius species known from Europe and neighbouring areas belong to: C. aedeagolobatus Rossaro, Magoga & Montagna, 2017; C. insolitus Caspers, 1987; C. gracilis Brundin 1956; C. antipovae Makarchenko & Makarchenko, 2011; C. dissipatus (Edwards, 1929), C. holmgreni (Jacobson, 1998), C. egorych Makarchenko & Makarchenko, 2017. Although some resemblance can be found between the five diagnosed and described species and other related members of the Chaetocladius genus, the taxonomic position cannot be clarified until current comprehensive work on the genus is complete. Geographical distribution of the five new species is currently restricted to the two Alpine Swiss glacial catchments: upper basins of the Rhône River and Muttbach streams; streams and lakes delimited by the Macun area. This highlights the importance of some high mountain ranges, considered as cold glacial enclaves and hotspots of endemism, in the preservation and persistence of autochthonous alpine relic species. Such species are considered as relevant biogeographic representative and their loss would be biologically indicative of global warming and climate change. Currently, there are only seven recorded Chaetocladius species from Switzerland: C. coppai Moubayed-Breil, 2017; C. laminatus Brundin, 1947; C. cf. longivirgatus Stur & Spies, 2011; C. melaleucus (Meigen, 1818); C. perennis (Meigen, 1830); C. piger (Goetghebuer, 1913); C. suecicus (Kieffer, 1916). Consequently, the description of the five new species increases the total number in the genus Chaetocladius to twelve for this country. Remarks and comments on the taxonomic position, ecology and geographical distribution of the new described species, with key to known male adults from the upper catchment of Rhône River (including Muttbach valley) are provided.

Ecology. Up to 50 male and female adults of H. lugubris have been examined based on large material collected in cold limnocrenes and pristine peat bogs located in NE-France. Emergence of chironomid fauna reported from February to March revealed that H. lugubris largely dominates the other associated species which are mainly encountered during the first seasonal inundations of floodplains of some rivers and streams located in both the Vosges Region and upper basin of the River Doubs. Species encountered in the same localities with H. lugubris include: Bryophaenocladius aestivus (Brundin, 1947), B. nidorum (Edwards, 1929), Chaetocladius dentiforceps (Edwards, 1929), C. melaleucus (Meigen, 1818), C. perennis (Meigen, 1830), Limnophyes pentaplastus (Kieffer, 1921), L. difficilis Brundin, 1947, Metriocnemus albolineatus Meigen, 1818, M. eurynotus (Holmgren, 1883), M. fuscipes (Holmgren, 1818), M. hirticollis (Staeger, 1839). Distribution. Hydrobaenus lugubris is actually widespread in Europe and the Palaearctic Region (FRIES 1830, ZETTERSTEDT 1850, GIARD 1904, SAETHER 1976, SERRA- TOSIO & LAVILLE 1991, BARANOV 2011b). In France, this species was reported for the first time from North Western areas (GIARD 1904). Records cited here from NE-France, after MOUBAYED- BREIL (2017), are coming from Vosges Region and the upper basin of the Doubs River (altitude 400–600 m). This is considered to be the second record from France.Published as part of Moubayed-Breil, Joel & Baranov, Viktor, 2018, Taxonomic notes on the genus Hydrobaenus with description of H. simferopolus sp. nov. from Crimea (Diptera: Chironomidae), pp. 347-355 in Acta Entomologica Musei Nationalis Pragae (Acta.

Synorthocladius federicoi sp. nov., a new species occurring in the middle basin of the Adige River, northern Italy (Diptera, Chironomidae, Orthocladiinae)

An adult male Synorthocladius was collected in the middle basin of the Adige River in the city of Verona, northern Italy. A combination of atypical characters for the genus signalled a new species. Synorthocladius federicoi sp. nov. is here diagnosed and described. The new species is known only from its type locality and is presumed to be a local biogeographical representative of the Italian Pre-Alps. An emended generic diagnosis, a key to known Synorthocladius from Europe and comments on the taxonomic position of the new species are given
