12mm. This species is very similar to pala as indicated above. The male genitalia have the tegumen unadorned, and the valves, though similar to those of pala, lack a subsidiary spine to the ventral process. The aedeagus has a robust, bifid apical spine (much more robust in the type specimen), beyond which is a small cluster of variably sized spines in the vesica. The females tentatively associated with this and the next species are both worn, with rather diffuse, dull rufous medial areas to the forewings.
Holotype. BRUNEI: 15m, Telisai, sandy heath forest and Gymnostoma, 13.12.1970, (Lt. Col. M.G. Allen), BM noctuid slide 19537.
Paratype. SARAWAK: Gunong Mulu Nat. Park, R.G.S. Exped. 1977-8 (J.D. Holloway et al.), Site 20, Mar.-Apr., W. Melinau Gorge, 150m. 422577 FEG 3, kerangas, BM noctuid slide 20042.
Taxonomic note. A possible female (slide 10819) from the paratypic locality has ovipositor lobes that are rather slender and acute. The ostium is flanked by a pair of processes, each consisting of a short, slender, inwardly directed spine and, well separate from it, a slender process more than twice as long, curved subbasally then straight, bearing a small number of subsidiary spines along its length. The ductus is relatively short and slightly convolute.
Geographical range. Borneo.
Habitat preference. All material is from lowland forest, two of the three specimens being from heath forest.
