Xyleutes lutescens Roepke
1957: 33; Barlow, 1982: 42.
Diagnosis. The ground colour is a dull orange, expressed on the wings adjacent to
the veins and on the margins. The spaces between all the veins of the hindwing
and the cubital and radial veins of the forewing are uniform grey; on the
forewing the spaces of the costal and dorsal zones contain darker, broad striae.
Taxonomic notes. Material from the main Sundanian islands is greyer than in the typical
form and placed by Roepke as a distinct subspecies grisescens Roepke.
The original description and illustration of ruficeps de Joannis
(1929, Ann. Soc. ent. France 98: 551, Hanoi) suggests this taxon may be
related to, or a senior synonym of, lutescens, though this did not occur
to Roepke (1957) who examined the type.
Geographical range. Lingga Archipelago, S. of Singapore; Peninsular
Habitat preference. The species frequents lowland forest, particularly
dry heath forest at Telisai in Brunei.
