Lophoptera submarginata sp. n.
10-11mm. The forewings are rather narrow, apically produced, medium dark
brown with dark fasciation and stigmata; the most conspicuous feature is a
diagnostic pale submarginal band, straight, parallel to the margin. The
hindwings have the basal half paler than the border, though the difference in
tone is variable. The male genitalia are similar to those of pallibasis and
allies. The female genitalia have a post-ostial invagination, no lateral lobes,
and the apophyses of the 8th segment are short and apically expanded as in pallibasis.

Paratypes. 30 examples, general data as holotype, various localities, BM noctuid

Habitat preference. The species was frequent in lower and upper montane
forest samples from G. Mulu but rare on the transect of G. Api. It was taken
singly in the kerangas and four specimens were taken at the Long Pala canopy
outlook site. There is a further specimen in the BMNH from G. Murud, Sarawak. It
would thus appear to be a predominantly montane species.
