Gymnoscelis imparatalis
(x 1.16)

Diagnosis and taxonomic notes. See Gymnoscelis confusata Walker. The general colouration is browner than in confusata. There is some variability in the female genitalia throughout the range of the species, particularly in the length of the ductus and the breadth of the ribbon of sclerotisation in the bursa: the latter is broader in material from the Pacific. The taxon indicata Walker is currently treated as a synonym of imparatalis but has facies more as in pseudotibialis and celebensis. The types of both of Walker's taxa lack abdomens, hence their association with the concept of imparatalis adopted by Prout cannot be confirmed with confidence.

Geographical range. Indo-Australian tropics east to Society Is. and Marquesas.

Habitat preference. The species probably occurs in both lowland and montane ecosystems. The only reliably identified specimen taken in recent surveys was from lower montane forest (900m) on the limestone G. Api.
