Hyposidra violescens Hampson,
1895, Fauna of British India, Moths, 3: 213.
Diagnosis. Both this and the next species have a distinct central angle to the
forewing margin. The ground colour is medium grey as in H. talaca Walker,
but shaded with black speckling. The hindwing postmedial is lined distally with
white; that of the forewing is finely white, angled subcostally and somewhat
broadened at the costa. The forewing discal mark is a black dash or chevron. The
two species are distinguished from each other in the description of the next.
Taxonomic notes. In Sumatra there also appears to be a distinct species flying at higher
altitude, but with genitalia (slide 16285) showing differences from those of violescens.
Geographical range. N.E. Himalaya, N. Vietnam, N. Thailand, Peninsular
Malaysia, Sumatra, Borneo. (The Sulawesi record in Holloway (1976) refers to a
dark specimen of a new species of the infixaria group).
Habitat preference. The species is infrequent in lowland forest, and has
also been recorded singly in lower montane forest on G. Mulu (1000m) and G. Api
