Chalcocelis albiguttatus

Chalcocelis albiguttatus

Chalcocelis albiguttatus larva on coconut in the Philippines. (M.J.W. Cock)

The female can be confused with Chalcoscelides castaneipars as discussed for the latter. The male is distinguished from other similar sized blackish species by the black circle on the forewing mentioned in the generic description. Specimens from Sundaland and Sulawesi have a prominent setose lobe centrally on the valve as illustrated and the valve apex is triangular. Specimens from New Guinea and Queensland have the setose lobe vestigial and the apex acute or with only a vestige of the dorsal subapical angle. The name hemistaura Lower ( = nephrochrysa Lower) is available for this eastern form at subspecific level. Material from Saleyer, near Sulawesi, is intermediate. Material from Mindanao and Luzon in the Philippines also has the valves with the setose lobe absent or virtually so, and the valve tapering to a simple point, but C. wilemani West, with a "female-coloured" male, has genitalia much as in typical albiguttatus: the status of Philippines taxa requires further investigation.

Geographical range. S. Thailand, Sundaland, Sulawesi; Moluccas, New Guinea, Queensland, ?Philippines.

Habitat preference. The species has been found to be infrequent in a variety of hill habitat types, mainly rainforest types such as lowland dipterocarp forest, kerangas and coastal forest.

Biology. The eggs, larva and its parasites are described by Kalshoven (1981). The eggs are transparent, flat, almost scale-like, laid singly or in small groups on the host-plant. The larva is convex, ovoid, gelatinous, transparent bluish to yellowish green with five indistinct lighter longitudinal stripes. It is polyphagous, the diet including Cocos (Kalshoven 1981), Coffea (Rubiaceae) and Erythrina (Leguminosae) (Piepers & Snellen 1900), Aleurites (Euphorbiaceae), Eugenia (Myrtaceae), Hydnocarpus (Flacourtiaceae), Acacia (Leguminosae) and Gardenia (Rubiaceae) (Corbett 1932).
