Taeniochilosia atriseta (Oldenberg, 1916):101

The genus Taeniochilosia comprises species with the bare face and eyes and black legs. Claussen (personal communication in Barkalov 2002) considers the dense and long pubescence of the arista to be an aberrant character. Barkalov (2002) performed an analysis of some other species with the bare eyes and partly yellow legs (the group of species close to C. caerulescens Meigen), and found no fundamental differences from Taeniochilosia in the structure of the hypopygium.

Barkalov (2002) considered Taeniochilosia as a aubgenus of Cheilosia. In C. Claussen's opinion (personal corrununication; in Barkalov 2002), T. atriseta belongs to the group of species, separated by Shatalkin (1975) into the subgenus Nigrocheilosia. Consequently, the name Nigrocheilosia Shatalkin, 1975 should be considered a junior synonym of Taeniochilosia.

In an earlier monograph devoted to the Cheilosia species from the Balcans, Vujic (1996) treated Taeniochilosia (=Nigrocheilosia) as a distinct genus. Barkalov (2002) disagreed with his view and wote: "the separation of a certain group of species in a genus presumes the existence of a clear morphological hiatus between this and other groups of the same rank, whereas nearly all characters on which the separation of Taenioehilosia is based are present in other subgenera. For example, the bare eyes and connate antennal sockets are typical of the subgenera Eucartosyrphus and Hiatomyia [considered in this LifeDesk as a different genus]; some features of the male genitalia structure can also be found in other subgenera (e.g., in Convocheila). In my opinion, an important argument for inclusion in Cheilosia is the typical "Cheilosian" habitus of the species of Taenioehilosia, mentioned above. All this confirms the subgeneric rank of Taeniochilosia Oldenberg, 1916 within the genus Cheilosia Meigen".
