Nigriblephara Gen.
n.
Type species: radula sp. n.
This genus contains three small species marked heavily with black on a
white ground. The male antennae are fasciculate and the fovea is absent.
In the male abdomen there is a strong, complex pair of coremata between
segments 4 and 5 and a multiple corematous structure associated with each
side of segment 7. Segment 8 is elongated. The genitalia have the uncus reduced,
ovate, set on a broad, squarely or sinuously shouldered tegumen. The juxta is
strong, more heavily sclerotised apically, scobinate in the type species. The
valve costa is narrow, with a complex zone of lobes and setae centrally,
opposite an irregular, sclerotised process on the sacculus. The aedeagus vesica
is large, irregular, with a sclerotised lobe reflexed subbasally.
The female genitalia (N. semiparata Walker only) have the
ovipositor lobes very elongate, extensile. The ductus is longer than the
ovipositor, slender, with the ovate bursa having a broad basal interior lobe of
sclerotisation that could represent the signum.
The three species are currently known only from Sundaland.
