Axinoptera ruficosta sp. n.
putative 7mm. The facies is very close to that of orphnobathra but the
postmedials, though as strongly flexed, are somewhat strongly angled. The angle
of the male costa is more distal than in orphnobathra, and the costal
zone is broadly rufous between the angle and the apex: the white marginal spot
of the hindwing is prominent. The facies of the putative female is difficult to
distinguish from that of orphnobathra, but the genitalia (slide 10793)
are different. The male has the valves bilaterally asymmetric, only the left one
having a long ventral arm.
The aedeagus vesica has a row of several slender cornuti, more than in
any other Bornean species. The female genitalia have the ductus much broader
than in orphnobathra, and the bursa is more globular, less elongate.
There is a distinctive pair of pouches on the lamella antevaginalis.
