Leucania? abbreviata Walker, 1862, J. Linn. Soc. (Zool.), 6: 180.
Kobes, 1997: 72, syn. n.
Diagnosis. The species is very similar to contrariata but has the
subapical white triangle on the forewing costa obscured by greyish suffusion.
The triangle has the distal side longer than the basal side, the latter slightly
bilobed, whereas in contrariata the basal side is longer and straight.
The postmedial is usually obscure. The male genitalia have the uncus distinctly
bilobed, and the valve is more elongate than in contrariata.
Taxonomic note. The male genitalia of the holotype of abbreviata (UM,
Oxford) match those of N. becki Kobes from Sumatra.
Geographical range. Borneo, Sumatra.
Habitat preference. The holotype (UM, Oxford) is from Sarawak, probably from
the lowlands. Two further males have been taken in recent surveys, from 1000m in
lower montane forest on G. Mulu, and from 150m in lowland dipterocarp forest
near the Danum Valley Field Centre. There is also a male in USNM from 1530m near
Kundasang on the south side of G. Kinabalu.
