Differs from the type species in having: SC approaching C in basal quarter of wing length and fused with it possibly near wing midlength (vs. approaching near wing midlength and fusing near its last quarter in the type species); the space between M 5 and CuA is about as wide as that between M and M 5 (vs. distinctly narrower); CuP disappears near the wing midlength (vs. reaching at least the apical quarter of the wing); 1A and 2A are distinctly apart near the base (vs. anastomosing or nearly so there); size small fore wing some 10 mm (vs. some 20 mm).</p><p>Description. Wing (unknown if fore or hind one) long and narrow (7.2 mm long and 2.35 mm wide as preserved, probable wing length 10–11 mm, some 3.5× as long as wide), with costal margin almost straight (slightly convex in basal and apical quarters). Costal space (between C and R) narrow throughout. All veins simple as preserved (that is, within basal 0.75 of wing length). SC approaching C since beginning of wing 2 nd quarter and becoming invisible (ending at C?) near end of 2 nd third. RS neutral (neither convex nor concave), starting near wing midlength. M concave, M 5 thick, convex, fork of M and M 5 near basal 0.2 of wing length, fork of M and CuA near its basal 0.1. CuA and CuP both concave, running almost touching each other, CuP ending near wing midlength. 1A and 2A distant from very beginning (with no subbasal anastomosis). All spaces between R, RS, M, M 5 and CuA, and between CuP, 1A, 2A and wing hind margin of comparable width (that one between M 5 and CuA not distinctly narrowed comparing that between M and M 5) and crossed with subvertical crossveins spaced almost regularly (even though often incompletely preserved).</p><p>Type material. Holotype PIN, 5516/99; Vyazovka-25, Upper Permian, Upper Vyatkian, Kulchumovo Formation; part and counterpart of wing lacking apex and with some deformation.</p><p>Etymology. The species is named in honor of the outstanding Russian entomologist Prof. Sergey Yu. Storozhenko (FSC Biodiversity FEB RAS, Vladivostok, Russia) on his 70th birthday.</p></div>	https://treatment.plazi.org/id/6244EC3F300AFFBDFF3EFD5AFC6BF9A5	Public Domain	No known copyright restrictions apply.
