Didigua seticornis

Appearance

This is a very variable species and can have the medial zone of the forewing suffused black or brown. The holotype of mesocausta has a brown medial zone but the genitalia are as in typical seticornis. Externally similar material from Sulawesi (slide 17941) has distinct male genitalia (shorter valves, an elongate, bifid, spined juxta, and a shorter, more dorsal spine associated with the ductus ejaculatorius in the aedeagus vesica), and is therefore not considered conspecific. The female genitalia of seticornis have a distinct diverticulum to the bursa that presumably accommodates the spine of the male vesica.

Distribution

Habitat

The species is common in the lowlands, extending with decreasing frequency up to about 1600m.
