Rhypotoses strigifimbria


Diagnosis and taxonomic note.
The males are marked rich dark brown in a similar manner to the species above, but on a fawn ground, the hindwing also being fawn. On the forewing, the medial zone can be more extensively shaded with brown. A possible female is illustrated, but this association is extremely tentative. A similar female from the Natuna Is. (slide 2440) has browner forewings with more extensive fasciae, but its genitalia have a basally sclerotised ductus as in the putative brooksi females dissected; the male has quadrilateral genitalia with a robust aedeagus as in brooksi.

Geographical range. Borneo, Sumatra.

Habitat preference. This is a frequent species of lowland forest, possibly with greater abundance towards upper altitudes of the zone. During the Mulu survey a number of specimens were taken at 900m in lower montane forest on the limestone G. Api, and at 500m on G. Mulu.

Biology. The species has been reared from larvae feeding on the flowers of Theobroma cacao (Sterculiaceae) in Sabah (Dr Chey Vun Khen, pers. comm.).
