Characoma albulalis

Characoma albulalis

This is the first of a sequence of four species with similar facies and male genitalia. Males in two of the species, but not albulalis, have the hindwing tornus produced and adorned with longer scales. The tegumen is considerably expanded where it overlaps the vinculum, and this overlap is only exceeded in
“Giaura” robusta Moore. The forewing facies of albulalis resembles that of the generally larger metalophota Hampson very closely but lacks the modified male hindwing of that species; also the male genitalia have a somewhat less pronounced overlap of the tegumen. In both sexes, albulalis has the anterior half of the forewing medial zone less variegated, but both species have forms where this is dark grey; in metalophota this dark grey extends more strongly back to the dorsum.

Taxonomic note. This group has an unusual structure of the base of the abdomen in both sexes (Fig 152), with bulbous apodemes supported from a slender, frame-like structure within the basal sternite.

Geographical range. Borneo.

Habitat preference.
The species is frequent in a range of forest types from the lowlands to about 1800m.
