Eupogonomyia setibasis Huckett, 1965a: 301 .

Thrichopticoides gymnophthalma sibirica Lavčiev, 1971: 220 . Syn. nov. Drymeia setibasis ; Sorokina, 2012a: 329.

Note. Lavčiev (1971) described the subspecies Thrichopticoides gymnophthalma sibirica based on one male from Sarma [256 km NE Irkutsk, 53º06'N 106º50'E], Irkutsk raion, Russia. The holotype of D. gymnophthalma sibirica should be in the Zoological Institute, Russian Academy of Sciences, St Petersburg, Russia, but it was not found there by Pont (2004) or by VSS. Although we have not seen the type, Lavčiev’s description of D. gymnophthalma sibirica , especially of the mid femur with several curved setae at extreme base of anteroventral surface and several strong setae on anterodorsal surface at base, and also his figures of the hypopygium and hind tibia, are the same as in D. setibasis Huckett. We have no hesitation in proposing this synonymy. The name sibirica Lavčiev is in any case a junior secondary homonym in Drymeia of Bebryx (now Drymeia ) sibirica Hennig, 1962 , and is therefore an unavailable name.

Remarks. All the above material from Wrangel Island collected by K. Gorodkov is located in the ZIN. Both sexes were well described by Huckett (1965a: 301) and the species can be easily recognized from his keys (op. cit.: 300). Flies were collected from flowers of Dryas integrifolia , Potentilla emarginata , Ranunculus sp.

Distribution. Known from North America (Alaska, the Yukon, Northwest Territories) and Russia.
