10-11mm. Externally this species resembles the previous two, and the male genitalia are similar to those of telisai. However, there are small but consistent differences in the genitalia: the valve is narrower, with the dorsal process shorter, downturned, and the ventral one much longer; the spine at the apex of the aedeagus is also bifid but slender, the bifurcation on a more definite stalk; there is a small spine opposite the bifurcate one.
Holotype. BORNEO: Sabah, Danum Valley, 5° (176) 01' N, 117° (176) 47' E, 20.x.1987, 100m (A.H. Kirk-Spriggs), primary forest edge, BM noctuid slide 19539.
Paratypes: 1 (slide 20041) as holotype; 1 (slide 20007) Bidi, SARAWAK, 1907-1908 (C.J. Brooks); 1 (slide 20039) SARAWAK: Gunong Mulu Nat. Park, R.G.S. Exped. 1977-8 (J.D.

Taxonomic note. A possible female from the Danum locality (slide 20140) has a pair of bifid processes flanking the ostium as in telisai, but the processes on each side are less strongly angled to each other at their junction, the inner one almost twice as long as the outer one, digitate, curving slightly outwards; the outer one is straight, tapering, acute.
Geographical range. Borneo.
