Ornithospila submonstrans

See key.

Taxonomic notes. Subspecies moluccensis has several peg-like setae on the sclerotised plate distal to the valve sacculus. The aedeagus has a sclerotised band bearing a series of four blunt spines that increase in size along the row, rather than the single bent spine of typical submonstrans. The taxon might be better treated as a distinct species.

Geographical range. Peninsular Malaysia, Sumatra, Borneo, Philippines; Moluccas (Obi, Bacan: ssp. moluccensis).

Habitat preference. This species is also frequent from the lowlands to almost 2000m.

Biology. O. submonstrans has been recorded as a defoliator of Shorea parvifolia (Dipterocarpaceae) in Malaysia (FRIM records).
