“Anoba”
kerangatis
sp.
n.
13, 14mm. The facies is atypical of the tribe Anobini, being
diffuse and irregular, but there is a tuft of scales on the forewing dorsum at
about one quarter as in many taxa of the tribe, and the male abdomen,
particularly the valve costa, has features consistent with it. The forewings are
shades of black and grey, diffuse pale fasciae consisting of: an arc from
subbasally on the costa to the centre of the dorsum; a more irregular
submarginal that, at its anterior, defines a black area at the apex. In the male
genitalia, the uncus is short, rather broad, with a small apical spine, and
lacks the large dorsal spine seen in pectinata and
rigida.
The valve costa has the expanded subbasal section typical of the tribe, and a
very pronounced marginal process at two thirds. The ventral and apical margin is
invested with setae that are directed to the interior of the valve. The aedeagus
vesica is convolute, scobinate in places, but lacks the prominent cornuti often
seen in other species in the genus and tribe.
