Permosialis ualentovae: Novokshonov & Zhuzhgova, 2004: 183 , fig. 6a, Pl. 10, fig. 2.

MATERIAL. Holotype PIN, No 1366/349, counterpart of forewing fragment; Russia, Kirov region, Malmyzh district, left bank of the Kityak River opposite the village of Bol’shoi Kityak; Upper Permian, Upper Kazanian, Belebei Formation; in Borissiak Paleontological Institute, Russian Academy of Sciences ( PIN RAS).

DIAGNOSIS. Differs from all other species of Permosialis by color pattern (three pairs of margined pale spots on darkened background) and venationally from all but P. belebei sp. nov. by two RS forks placed close to each other and far from both R base and wing margin, and from P. belebei sp. n. (as well as from all or most of other congeners) by reduced (short and narrow) fork of CuA.

DESCRIPTION. Forewing comparatively narrow (not as wide oval as P. sibirica ), with characheristic color pattern of round dark margined pale spots on somewhat darkened background: two spots in subcostal area and one in each interradial, radiomedial, mediocubital and cubitoanal ones that form three vertical pairs (first subcostal spot with cubitoanal one, second subcostal with radiomedial, and interradial with mediocubital one). Costal and subcostal spaces both moderately wide (costal one wider), SC almost straight, with few almost regularly spaced short branchlets (6 visible). RS 3-branched, both forks placed close to each other but not to RS base. M stalk apparently free, fork leveled with first RS fork. M 5 not preserved. CuA stalk and branches concave, fork short, narrow. CuP curved apical. 1A concave.

MEASUREMENTS. Forewing fragment length 12.6 mm, supposed full length about 16 mm, width 7.5 mm.

NOTES. Novokshonov & Zhuzhgova (2004: 183) list three paratypes of the present species. Of them, 1366/379 and 1366/463 are described as a different species P. belebei sp. n . herein (see below), and PIN, No. 1366/382 represents a fragmentary hind wing which can be hardly ascribed to P. ualentovae because it shows a darker subapical transverse belt (vs. margined spots in fore wings of P. ualentovae ) and would be rather treated as Permosialis sp. until more conclusive information appears.
