“Parallelia” calefaciens

. The forewing colour and facies is similar to that seen in Bornean representatives of the next genus, except the central straight fascia between it and the postmedial is more strongly defined, and usually has a paler zone grading away basad rather than one distad. There is also a diagnostic but small pale dot in the cell basal to the straight line.

Taxonomic note. Dissection of further males amongst the rigidistria complex discussed by Holloway & Miller (2003) has revealed presence of a double corema to the valve rather than the single one interpreted in old slides. With the bilateral symmetry of the genitalia, this would indicate relationship to Bastilla, but the female lacks an antevaginal plate. This dissection has also indicated that rigidistria Guenée is restricted to the Indian Peninsula and Sri Lanka and has the valve costal process bifurcated into two long, slender, curved processes that, with the similar curvature between their bases, almost form a circle. The more dorsal one may have a small lateral spine. The concept of calefaciens presented here is that of the Doubleday (?Silhet) syntype, a male (slide 18381); the Sri Lankan syntype has not been located. The complex is represented further east by correctata Walker stat. rev. (= crenulata Bethune-Baker, syn. n.) where the valve process has a more distal, right-angled bifurcation. This species is known from the N. Moluccas to the Bismarcks and probably the Solomons (not dissected). The type material is female, but Mysol, the type locality, is adjacent to New Guinea, between it and the northern Moluccas. A further species with much paler forewings, “P”. lilacea Bethune-Baker, is found in New Guinea.

Geographic range. N.E. Himalaya, Thailand, Sundaland, Philippines to Seram.

Habitat preference. The species is frequent in mostly forested localities from the coast to 1930m.

Biology. The adult has been noted as a fruit piercer in Thailand (Bänziger, 1982; Kuroko & Lewvanich, 1993).
