Diagnosis
and taxonomic note. This
is one of three very similar species with male forewing venation modified as in
Fig 4a, most of the strongly curved radial sector veins and M1 arising from a
narrow areole, and with the costa reflexed back centrally to support a fringe of
hairs over the discal part of the cell. The forewing pattern has a strongly
zig-zagged postmedial that, in the male, tracks the strong curvature of the
veins distal to the cell. The females have the postmedial less extensively
zig-zagged and a generally more speckled facies; they are difficult to associate
with the males. Males of the three species can be distinguished externally by
variation in the venation around the areole. The facies of cuneifera
is similar to that of the next species except the forewing fringes are
usually tinged brownish, and the antemedial is more broken as in the third
species in the group. The male areole is very narrow, the radial sector veins
arising connate or stalked from it. The male genitalia have the costal process
of the valve absent, but the saccular process is strong, upcurved, tapering to a
point. The aedeagus vesica is globular with about ten slender cornuti arranged
around it. The females have an irregularly shaped bursa with rather thick walls,
fine scobination basally and a meandering zone of coarser spining distally. A
similar bursa structure is seen in Lyclene
luzon Wileman & South comb. n. (Philippines) but the coarser
spining is more regular and linear.
