Khramov, Alexander V. & Makarkin, Vladimir N., 2015, New fossil Osmylopsychopidae (Neuroptera) from the Early / Middle Jurassic of Kyrgyzstan, Central Asia, Zootaxa 4059 (1), pp. 115-132 : 122-123

Genus Osmylopsychostoechus gen. nov.

Type species. Osmylopsychostoechus sogulensis sp. nov.

Diagnosis. Forewing relatively narrow; no crossveins in costal space; MA once deeply forked; MP1 dichotomously branched distally; CuP once or twice deeply forked; outer gradate series of crossveins in radial space distinct, not continuing to cubital space.

Etymology. From Osmylopsychops , a genus-group name, and the Greek stoichos, row, in reference to similarity of the venation of the new genus to that of both Osmylopsychopidae and Polystoechotidae . Gender masculine.

Remarks. The new genus may be distinguished from other genera of Osmylopsychopidae by relatively narrow forewings. The genus Stenopteropsychops Peng et al., 2015 from the Middle Jurassic of China also has narrow forewings (Peng et al. 2015) but it differs from the new genus by the shallowly forked CuP and the presence of broad pale fasciae (on which the venation are not preserved).

The shape and venation of Osmylopsychostoechus gen. nov. are similar to those of Polystoechotidae but easily distinguished from all genera of that family by the deeply forked MA in the forewing (the forewing MA in Polystoechotidae is always forked only distally).
