Clethrogyna turbata Butler comb. n.

Orgyia turbata Butler, 1879, Trans Linn. Soc. Lond., (2) 1: 560.

Diagnosis

The female is flightless, with vestigial wings. The male forewings are rather rounded, a rich rufous brown, with orange patches subapically and subdorsally just distal to a weak, double postmedial that consists of two fine, crenulate black lines that are angled at about one third from the costa.

Taxonomic notes

The species was misplaced in Orgyia. The rather uniform rufous forewing facies and the structure of the male genitalia are more consistent with placement in Clethrogyna.

Further data and illustrations of the life history of Clethrogyna turbata in Borneo have been published by Chung (2003) and Chung et al. (2006, 2009b). Host plants added to those listed in Part 6 and by Robinson et al. (2001) are Terminalia (Combretaceae), Bauhinia (Leguminosae; feeding on flowers only) and Ixora (Rubiaceae).
