Type species: Eutane nivea Hampson, 1905 .

Etymology. The generic name is a combination of its type species’ name nivea and the generic name Eutane , which the species of the new genus were previously associated with. Gender feminine.

Diagnosis. Small moths with short trigonal wings and white colouration; pattern is reduced and present as yellowish terminal line and cilia with black spots at anal forewing margin. In some species a black discal dot is present. The male genitalia are characterised by the combination of the following characters: (1) the vinculum is basally broad and heavily sclerotised, with a narrow rectangular tip (an autapomorphic feature); (2) the valva is strongly broadened basally and strongly narrowed distally, with ventral margin having a small trigonal process subapically; (3) costa is narrow, its distal half is strongly setose (an autapomorphic feature); (4) the sacculus is broad but short and is half the length of the valva; (5) the distal saccular process is present, small, finger-like; (5) aedeagus is narrowed distally and slightly curved medially; (6) the aedeagus vesica has several short granulated diverticula. In the female genitalia, (1) the sclerotised ductus bursae with an arcuate margin of ostium bursae; (2) the ductus bursae is elongated, pear-shaped, weakly sclerotised and scobinated posteriorly; (3) the appendix bursae is small, narrow, elongated, curved, situated ventroposteriorly.

Distribution. Malay Peninsula and Borneo.

Number of species. The genus comprises four valid species.
