Stauropus virescens Moore,
1879, Proc. zool. Soc. Lond. 1879: 404.
Stauropus obscuratus van
Eecke, 1929, Zool. Meded. Leiden 12: 165, syn. n.
Benbowia dudgeoni Kiriakoff, 1967: 53, syn. n.
Diagnosis. See Benbowia kiriakoffi sp. n. Some specimens (e.g. from Borneo and Sumatra) have the
basal area of the forewing and the costa of the hindwing broadly suffused with
black (illustrated), but the male genitalia show no constant differences from
those of typical virescens. The holotype of obscuratus is an
extreme of this form.
Taxonomic note. The male genitalia illustrated by Kiriakoff (1968: 136) for virescens
are those of the next species; the holotype of virescens has
genitalia very similar to those of that of dudgeoni, hence the synonymy
Geographical range. N. E. Himalaya, Taiwan, Sundaland.
Habitat preference. Records have been infrequent but from a range of rain
forest habitats from the lowlands to 2000 m.
Biology. Barlow (1982) described the larva as green with a dorsal purple line and
similar colour on the legs. The spiracles are white and there is a sublateral
yellow line. The body is thickened centrally and the anal segment is bifid.
