Epiosmylus longicornis Panfilov in Dolin et al. , 1980: 100 (by original designation). Diagnosis. Wings narrow, subacute apically; RP with 5–6 branches; RP1 originating far from origin of RP (1/3–1/ 2 wing length); FW medial fork close to but distal to origin of RP; MA with few branches near wing margin in both wings; FW MP pectinately branched with 3–6 branches; HW MP elongate, pectinately branched; FW CuA pectinately branched (3–5 branches); FW CuP pectinately branched (3–7 branches); HW CuA elongate with widely spaced pectinately branches; HW CuP simple; FW A1 pectinate (3 widely spaced branches). Comments. The genus is the type of the family Epiosmylidae Panfilov in Dolin et al. , 1980 , which was synonymised with Gumillinae by Menon & Makarkin (2008) . Epiosmylus is differentiated from most other gumilline genera by the first RP branch originating on RP at least 1/3 wing length and relatively few branches of RP (5–6). It appears closely related to Enodinympha and Tenuosmylus . The wings of these genera are relatively narrow compared to other genera (e.g., Gumilla ). Included species .
