Rhypotoses strigifimbria Walker
1862, J. Linn. Soc. (Zool.), 6:126.
1865, List Specimens lepid. Insects Colln Br. Mus., 32: 333.
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.).
