species: nulliferana Walker, Borneo.
The small type species of this genus has forewing venation similar to
that of Neoduma, but the cell is much
shorter, extending only two thirds of the way to the apex (Fig 10h). The
hindwing has five veins (excluding Sc) arising from the cell. The forewing is
brownish grey, with a pale yellowish zone extending down from the base along the
costa to the apex. Hampson (1900) gave a detailed description of wing pattern
that is not apparent in the specimen today. There are a few black scales in the
discal area that are not seen in the specimens taken more recently. The holotype
is badly damaged and lacks an abdomen; it is not entirely clear that the three
specimens taken recently and referred to below are correctly assigned to it.
They are also in poor condition but are of similar general appearance, and the
male dissected has similar forewing venation, though the wing in better
condition is somewhat distorted.
Fig.10h: Tospitis nulliferana Walker
The genitalia of this male (slide 4974) have rather flimsy valves,
triangular but with a broadly rounded distal margin; the costa is slightly
thickened to about one third. The tegumen is twice as long as the vinculum, the
uncus is simple, slender, and there is a suprascaphial thickening. The aedeagus
vesica contains a small ovate sclerotisation.
Apart from the type species, the genus also contains brunneiplaga
Hampson from Bhutan, but this may well not be congeneric.
