Abaciscus shaneae sp. n.
17mm. The hindwing margin has a distinct angle at vein M3. The pale
cream ground colour is extensive over the half of the forewing basal to the
postmedial and in an apical patch. It is crossed by fasciae and only a light
irroration of dark brown. The zone basal to the hindwing postmedial is also
paler but much more heavily suffused brown except just basally. On the
underside, the pale areas are as on the upperside except the entire basal zone
of the hindwing is pale. The apex of the abdomen is similarly pale. In the male
genitalia the uncus is acutely bifid, the valve cucullus is apically squarish,
and the aedeagus has a slender, apically hooked cornutus.
