New Dysmorphoptilidae (Cicadomorpha) from the end-Permian and Middle Jurassic of Siberia: earliest evidence of acoustic communication in Hemiptera and the latest find of the family Author Shcherbakov, D. E. text Russian Entomological Journal 2022 2022-06-30 31 2 108 113 http://dx.doi.org/10.15298/rusentj.31.2.02 journal article 10.15298/rusentj.31.2.02 0132-8069 13179510 Eumorphoptila pritykinae Shcherbakov , sp.n. Figs 9–10 . MATERIAL. Holotype PIN 1255 /1608±, complete tegmen; Kubekovo near Krasnoyarsk , Emel’yanovo district , Krasnoyarsk Krai ; upper Itat Formation , Middle Jurassic (Bathonian). DESCRIPTION. Tegmen 6.0 mm long, elongate (3.0:1), acutely rounded at apex; postnodal part short (about 1/4 tegmen length); emarginations distal to dSc and at CuA1 very slight. Costal margin convex, more so at base; precostal carina narrow; CP faint, bSc short, high arched. Costal area narrow, with oblique swelling in strigil area, but strigil not detected. RA to dSc more than twice as long as R stem; one weak prenodal R branch before R fork and two strong on RA. RA and anterior M branch with short forks; posterior M branch fused with CuA1 for half of its length. Basal cell very short, closed with short M+CuA anastomosis. CuA stem weak proximally, close to claval furrow; CuA2 crossveinlike. Claval veins close-set and displaced anteriorly, 1A bisinuate. Commissural margin with 10 regularly spaced small tubercles. Narrow marginal membrane posterior to tegmen apex. Tegmen and veins pale; membrane entirely punctate, coarser in postnodal part (appearing almost areolate); veins with bases of setae, larger on RA and claval veins. ETYMOLOGY. Named after Lyudmila N. Pritykina, a Russian paleoentomologist who collected many fossils at Kubekovo.
