Scopula pulchellata
(x 1.16)


Diagnosis. The species resembles a small version of S. voluptaria Prout, with the forewing postmedial complex of fasciae picked out darker at the dorsum and beyond the discal spot. The other fasciae are more regular, less crenulate and the marginal black marks are linear rather than punctate.

Taxonomic notes. Features of the male genital capsule are constant across the range of the synonymy presented above, though there is some variation in the lengths of the cerata, with the right one always shorter than that on the left. Further work is needed to establish the validity of the various subspecific categories. There are Oriental species with similar facies, e.g. S. addictaria Walker (Sri Lanka), S. bispurcata Warren (N.E. Himalaya) and S. malayana Bšnziger & Fletcher (Peninsular Malaysia) with valve processes more bilaterally symmetrical, lacking the curvature of those of pulchellata.

Geographical range. Indo-Australian tropics from India to Taiwan and Solomons, but apparently does not occur in Australia.

Habitat preference. The species is rare, known from Pulo Laut in the south and from a Pinus caribaea plantation at Brumas in the lowlands of Sabah.

Biology. A member of this facies group was reared from Nephelium (Sapindaceae) in Peninsular Malaysia (unpublished IIE records), and S. malayana has been recorded at mammalian lachrymal secretions by Bšnziger & Fletcher (1985).
