Eugnathia cithara Swinhoe comb. n.

Cerynea cithara Swinhoe, 1902, Ann. Mag. nat. Hist. (7), 9: 169.

Diagnosis

The wings are pinkish grey, the forewings with the costal band more of a fawn colour, relatively broad and with a dark, oblique cleft in the posterior border just distal to its centre. The cleft is associated with a black, arcuate line within an oblique, darker band of ground colour that runs to beyond the cleft and then flexes out to the centre of the distal margin.

Taxonomic note

The two Bornean females have the bulge at the end of the forewing costal band more flattened posteriorly than in other material. The valves of the male genitalia are narrow and elongate after becoming stepped in on the costal side adjacent to the base of the saccular process.

Geographical range

Peninsular Malaysia, Borneo.

Habitat preference

Six specimens have been recorded, one from disturbed coastal forest at Seria and two from dipterocarp forest at 300m in the Ulu Temburong in Brunei, one from alluvial forest by the S. Melinau near G. Mulu, one from lowland forest in the Barito Ulu and one from upstream from Pontianak in Kalimantan.
