Euporismites Tillyard in Tillyard & Dunstan, 1916

Type species. Euporismites balli Tillyard in Tillyard & Dunstan, 1916: 44 (by original designation).

Diagnosis. Forewing costal area with subcostal veinlets simple; branches of RP numerous, strongly sinuous distally, radial crossveins dense, except in distal part; outer gradate series apparently absent; end-twigging largely absent in medial and cubital regions; HW with MP relatively deeply forked; CuA probably strongly pectinate.

Comments. The type species was described based on a compression fossil hind wing fragment. This was later re-examined by Riek (1952) who assigned to this species an apical 1/2 of a forewing from the same locality and horizon. Later, these two specimens were re-examined by Lambkin (1987) who assigned to the species another hind wing fragment from a nearby locality (i.e., Dinmore) of the same horizon. It is very possible that the holotype and additional specimen represent different species and maybe even subfamilies. Lambkin (1987) mentioned some differences between the two but consider them as examples of intraspecific variation. The hind wing venation of the holotype is similar to Euporismus (Stenosmylinae) as believed by Tillyard & Dunstan (1916) and Riek (1952) (cf. Tillyard, 1916, fig. 1, and Lambkin, 1987, fig. 1). The incomplete preservation of the holotype does not allow precise determination of the subfamily, but the venation of the Dinmore specimen certainly belongs to Kempyninae based on the presence of the basal sinuous crossvein 1r-m and the deeply forked MP.
