Osmylopsychostoechus View in CoL sp.

Fig. 9 View FIGURE 9

Description. Hind wing ca. 20 mm long as preserved (estimated complete length ca. 22 mm), ca. 9 mm wide. Costal space relatively broad, poorly preserved. Preserved subcostal veinlets long, forked. Subcostal space relatively broad; definite crossveins not detected. Space between R1, Rs narrowed towards apex; crossveins scarce.

Rs with 18 branches; Rs1 deeply forked near origin; other branches irregularly forked distally at different distance from margin. Radial crossveins not numerous, irregularly arranged; outer gradate series incompletely preserved. MA deeply forked (slightly proximad fork of Rs1); distal portion not preserved. Distal nygma probably located in proximal dilation of intra-MA space. MP forked somewhat distad fork of MA. MP1, MP2 parallel for entire length; distal branching of MP1 not preserved; MP2 few branched, probably pectinate (not completely preserved). Intra- MA space with one distal crossvein. CuA strongly concave, pectinate, with eight rather long branches, all once or twice forked; three branches deeply forked. CuP probably pectinately branched, with three branches, two of them deeply forked. A 1 in general dichotomously branched. A2 pectinate, with at least seven rather long branches, some forked. A3 not preserved. Crossveins not detected posterior to CuA except one between CuP, A1. Trichosors poorly preserved.

Material. Specimen PIN 1526 / 118 (part, counterpart), a nearly complete but crumpled hind wing, housed in PIN.

Locality and horizon. Kyrgyzstan: Sai-Sagul; late Early Jurassic to the early Middle Jurassic.

Remarks. This hind wing is assigned to the genus Osmylopsychostoechus gen. nov. because of its relatively narrow shape. Unfortunately, the venation of the hind wing of Osmylopsychostoechus sogulensis sp. nov. is almost unknown, but its wing shape appears to be the same in the paratype PIN 2384/472. Therefore, it is quite possible that this hind wing may belong to this latter species.
