03DE87A3C52BFFEBD856A62DFAEAC781.taxon	description	DESCRIPTION. Tegmen 12.0 – 13.5 mm long, elongate (2.7: 1), transversely truncate apically, with distinct apex and tornus (posterior apical angle). Costal margin convex near base, nearly straight (not concave) distally; precostal carina narrow except near base; CP long, strong; bSc long, low arched. R stem arched forwards proximally, as long as RA to dSc. dSc very long, slanting, continuing proximal RA. RA with 2 – 3 postnodal branches less oblique than dSc; prenodal branches barely visible or absent. RP with small fork. M forked distal to CuA, pectinate backwards, with 3 main branches, M 1 with small fork. Basal cell long, closed with arculus. CuA fork long, CuA 1 arched forwards, CuA 2 joining margin distant from claval apex. Three crossveins. Claval veins widely separated, nearer to sides of clavus; Pcu gently curved, joining margin about 2 / 3 clavus length. Tegmen entirely covered with fine punctures on upperside (coarser on clavus) and stub-like microtrichia on underside (apparently forming plastron). In costal area near base these microtrichia merge into closely packed microscopic ridges covering elongate oval fingerprint-like area (strigil) about 1.3 x 0.6 mm; ridges more dense in proximal part of strigil (10 per 100 µm) than in its distal part (6.5 per 100 µm) Ambient vein not corrugated; marginal membrane narrow. Tegmen brownish, more so towards base, especially in costal area and on clavus; precostal carina dark brown.	en	Shcherbakov, D. E.

03DE87A3C52BFFEADACAA4BCFE07C28C.taxon	description	COMPARISON. Distinct from other genera in the elongate convex tegmen with a small postnodal part and raised veins with few short distal branches. Similar to Dysmorphoptila notodon Shcherbakov, 1988 (Bajocian, southern Mongolia) in the strong prenodal branches on RA and presence of prominences on the commissural margin, but in the latter the postnodal part is much longer, limited by distinct emarginations, distal vein branches are more numerous, and prominences are larger and spine-like. Two other dysmorphoptilid genera known from the Jurassic differ from Eumorphoptila gen. n. in the more developed postnodal part with longer vein branches and CuA fork (Mesoatracis reducta Becker-Midgisova, 1949, Toarcian, Kyrgyzstan), or the sinuate costal mar- <Рис. 1 – 8.

CuA stem weak proximally, close to claval furrow; CuA 2 crossveinlike. Claval veins close-set and displaced anteriorly, 1 A bisinuate. Commissural margin with 10 regularly spaced small tubercles. Narrow marginal membrane posterior to tegmen apex.
