Lambkin, Kevin J., 2016, Revision of the Dysmorphoptilidae (Hemiptera: Cicadomorpha: Prosboloidea) of the Queensland Triassic — Part 2, Zootaxa 4092 (2), pp. 207-218 : 211-213

Eoscartoides dmitryi sp. nov.

( Figs 7–9 )

Material. Holotype right tegmen QM F58591 , Dinmore, collected by Robert Knezour. Three paratype tegmina, Dinmore: QM F13625; ACC I.36 +; RKC: QM F58592 .

Description. Tegmen c. 18–19 mm long (holotype c. 18 mm), 7.5 mm wide, length/width 2.5, anterior margin convex except at base which is somewhat truncate; stem of R shorter than in M. bryani , its primary fork before clavus ½ length, with 0 or 1 simple costal veinlet; stem of RA with 1 simple costal veinlet; stem of RA1 enters costal margin at about ½ tegmen length, with 2 anterior branches; RA2 with 4–5 branches, sometimes with an endtwig; RP simple or with an up-curved terminal fork; M1 and M3+4 with deep terminal forks; CuA2 much shorter than CuA1; tegmen surface somewhat darkly suffused, noticeably darker in basal costal space, along costal margin, in punctate area of clavus, and along the veins ( Fig. 9 ).

Notes. Eoscartoides dmitryi , from the Dinmore site of the Blackstone Formation, is distinguished from its congeners by its larger size, stronger terminal forking of RP and M, and the shorter CuA2. The specific name honours Dmitry Shcherbakov of the Russian Academy of Sciences. It is only through his ground-breaking work on the classification of fossil Hemiptera that the present study has been possible.
