Diascoides Gen. n.
Type species: metaphaea Walker.
The forewing facies of the three species included in this genus is akin
to that of Lophoptera pustulifera Walker: shades of rich brown to fawn,
the fasciae rather obscure, mottled, and with a faint, diffuse, dark line
running from the costa at two fifths to the margin (the dorsum in pustulifera)
just subtornally; there is a diffusely darker spot submarginally just
anterior of centrally. The hindwings are a darker, duller brown than the
forewing and do not have a basal hyaline zone.
In the male genitalia the uncus is deeply bifid, the two processes very
slender. The valves are invested densely with fine, dorsally directed setae;
there is a basal harpe and various lobes from the costa.
The female genitalia have a very slender bursa that lacks a signum, and
the ostium is flanked posteriorly by small sinuous folds or has a small bibbed
flap posteriorly.
The genus is best defined by the forewing facies and, particularly, the
bifid uncus.
