New taxonomic notes on the genus Coenosia Meigen (Diptera: Muscidae), with the description of four new species from North-East Russia and the Altai Mountains

Summary

Four new species of Coenosia Meigen, 1826 are described from the Magadan region, Chukotka Autonomous Okrug and Altai Mounts (Coenosia galina n. sp., C. gorodkovi n. sp., C. koni n. sp., C. adriani n. sp.). Descriptions of the unknown females of C. tschernovi Sorokina, 2014 and C. wrangelensis Sorokina, 2012 are given. Three new synonymies are proposed: Coenosia (Hoplogaster) elegans Huckett, 1965, n. syn. of Hoplogaster baicalensis Schnabl in Becker & Schnabl, 1926; Coenosia tangera Sorokina, 2009 n. syn. of Coenosia (Hoplogaster) conflicta Huckett, 1965; Coenosia carinata Cui & Li, 1996 n. syn. of Hoplogaster morrisoni Malloch, 1924. Images of the new species and the male terminalia are given. The cytochrome oxidase I gene sequences (CO1) of two new species and nine other species are provided and discussed. The distribution of the Coenosia apukaensis species-group is discussed.

Résumé

Nouvelles notes taxonomiques sur le genre Coenosia Meigen (Diptera : Muscidae), avec la description de quatre nouvelles espèces du nord-est de la Russie et des montagnes de l’Altaï. Quatre nouvelles espèces de Coenosia Meigen, 1826 sont décrites de la région de Magadan, du district autonome de Tchoukotka et des monts Altai (Coenosia galina n. sp., C. gorodkovi n. sp., C. koni n. sp., C. adriani n. sp.). Les descriptions des femelles inconnues de C. tschernovi Sorokina, 2014 et C. wrangelensis Sorokina, 2012 sont données. Trois nouvelles synonymies sont proposées : Coenosia (Hoplogaster) elegans Huckett, 1965, n. syn. de Hoplogaster baicalensis Schnabl in Becker & Schnabl, 1926; Coenosia tangera Sorokina, 2009 n. syn. de Coenosia (Hoplogaster) conflicta Huckett, 1965; Coenosia carinata Cui & Li, 1996 n. syn. de Hoplogaster morrisoni Malloch, 1924. Des illustrations des nouvelles espèces et des terminalia mâles sont données. Les séquences du gène de la cytochrome oxydase I (CO1) de deux nouvelles espèces et de neuf autres espèces sont fournies et discutées. La distribution du groupe d’espèces de Coenosia apukaensis est discutée.http://www.zoobank.org/urn:lsid:zoobank.org:pub:BE7D3958-9826-439C-8EA3-3F35EFC4B304

I especially thank Jade Savage and Bishop’s University (Quebec, Canada) for the DNA barcoding data and for her help in interpreting these data. I would also like to thank Jim O′Hara (Ottawa, Canada) and Jade Savage (Quebec, Canada) for organising my visit to the Canadian National Collection of Insects where I had the opportunity to study the Nearctic species and the type material of Coenosia.
