Cleora alienaria

This and the next two species are somewhat similar in general appearance. C. concentraria Snellen is distinguished by the less crenulated postmedials, that of the hindwing being distinctively angled. The discal spot of the forewing is more clearly defined in alienaria than in C. pendleburyi Prout, and the forewing postmedial of the latter is generally less angled. C. pendleburyi has a more variegated appearance as a rule. The male genitalia are diagnostic, and dissection is recommended where identity is unclear on external features.

Geographical range. Indian Subregion to Sundaland and Lesser Sundas as far east as Timor. On Christmas I. (Indian Ocean): ssp. fumipennis.

Habitat preference. There is only a single Bornean specimen in the BMNH collections, a male from Tenom in the lowlands of Sabah. However, the species is being recorded in some abundance from plantations of Acacia mangium and Paraserianthes falcataria (Leguminosae) in the lowlands of Sabah (Chey, Speight & Holloway, 1993).

Biology. The larva has been reared from Paraserianthes by Chey Vun Khen and staff at the Forest Research Centre, Sepilok, Sabah. It is leaf-green, robust, with fine linear marbling. On A2 there is a pair of brown tubercles dorsolaterally, with a narrow, lenticular, transverse white bar anterior to them. The white bar is divided centrally by a black triangle. Prout (1929b) noted a host-plant record from 'Cinnamonea', presumably Cinnamomum (Lauraceae), and D. Stüning (in litt.) has reared the species from Sambucus (Caprifoliaceae) in N. Thailand.
