Polypogon kurokoi
Diagnosis. The build is relatively robust, and the forewings are somewhat narrow. The facies of the forewing are distinctive, medium grey, with a darker medial zone and fasciation. The antemedial and postmedial are distinctly doubled, the former more or less transverse, the latter much more sinuous, with the dark, lunulate, discal mark interior to one of the convexities basad. There is an irregular submarginal, but this is finer and fainter. The hindwing is a paler grey, with faintly darker postmedial and submarginal fasciae. The male genitalia have robust valves that taper to a small, bifurcate apex, but there are no processes terminating the costa or the sacculus.
Taxonomic note. There is some variation in ornamentation of the aedeagus vesica and the bifurcate valve apex, but material from each locality is insufficient to explore this further. The general form of the male genitalia and eighth abdominal segment is similar to that of classeyi.
Geographical range. Japan (Ryukyu Is.), Taiwan, Sri Lanka, Borneo.
Habitat preference. A single male (slides 20147 (genitalia), 20195 (foreleg)) was taken in lowland forest of the Barito Ulu in Kalimantan. Three specimens were taken in both logged and unlogged lowland forest at 170m near the Danum Valley Field Centre in Sabah (S.J. Willott, unpublished data).
