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)
(

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.
