punctimarginaria Leech comb. n.
Boarmia punctimarginaria Leech,
1897, Ann. Mag. nat. Hist. (8), 19: 422.
Boarmia subpictilis Prout,
1932, Novit. zool. 38: 115, possible synonym.
Diagnosis. This is a small dull, dark brown species with fasciation only weakly
evident. It is distinguished by a submarginal row of white dots on both wings,
that in the space posterior to vein M3 are more prominent than the rest.
Taxonomic notes. Association with Microcalicha is based on genitalic characters
rather than external ones: in the male, the cucullus almost spans the entire
width of the valve; there is a basal central process as in M. sordida but
broader and more densely and finely setose; the female genitalia are typical of
the genus. The original description of subpictilis from Borneo appears to
be of punctimarginaria, mentioning the submarginal white dots, but the
size given seems large. The type material in the Hamburg Museum was probably
destroyed during the war.
Geographical range. China, Borneo, Sumatra, Peninsular Malaysia.
Habitat preference. All material seen is from lowland forest, but the
species is rare.
