Eoscartoides bryani Evans, 1956: 221, fig. 18A; Evans 1961: 20, figs 4A–4C. Mesonirvana abrupta Evans, 1956: 192, fig. 5E. Syn. nov.

Material. Holotype left tegmen UQG C172, paratype tegmina UQG C677/680+, C933/934+, holotype tegmen of Mesonirvana abrupta, UQG C1652, all Mount Crosby Locality A. 12 additional tegmina, Mount Crosby: Locality A: QM: F3693a/b+, F3695a/b+, F3697a/b+, F58584, F58585 +, F58586 +, F58587 +, F58588 +, F58589 +, F58590 + (the latter seven listed by Evans (1961) as UQE S4, S5/5A, S9, S10/10A, S15, S17/17A and S19/19A); Locality B: ACC I.2 a/b+, I.120.

Description. Tegmen 11.4–12.4 mm long, 5.0–6.0 mm wide (holotype 5.9), length/width 2.1-2.4, anterior margin convex except at base which is somewhat truncate; R with 0 or 1 simple costal veinlet; primary fork of R at about clavus ½ length; stem of RA with 0, 1 or 2 simple costal veinlets; stem of RA1 enters costal margin at about ⅔ tegmen length, with 1-3 anterior branches, one sometimes with an end-twig; RA2 with 3-5 branches, sometimes with an end-twig; RP simple, more or less straight, or at most very slightly up-curved apically; M1 simple or with a terminal fork; M3+4 simple, in one specimen only with a terminal fork; CuA2 only slightly shorter than CuA1; tegmen surface apparently somewhat darkly suffused, noticeably darker in extreme basal costal space and narrowly along costal margin.

Notes. The species demonstrates a degree of intraspecific variation in tegmen size and proportions, and in the form, spacing and number of branches of RA1 and RA2 (Figs 1,3).
