Etanna viridifascia sp. n.


Etanna viridifascia (paratype)

, (Peninsular Malaysia) 8-9mm. The forewing facies is somewhat atypical of
Etanna, with an irregular green postmedial and a similar antemedial dividing the wing into grey basal, medial and marginal thirds; the green fasciae are edged finely with black. However, the male genitalia are consistent with placement in Etanna, though the eighth abdominal segment is deep, each sclerite frame-like and containing a prominent pair of hair-pencils. The uncus and tegumen are complex, with fine bands of thickening; indeed the former may be vestigial. The valves are reduced to very narrow strips, and the scaled process is similarly long and slender. The large saccus and tegumen/vinculum junction are typical of Etanna also. The aedeagus vesica has a single cornutus, only seen elsewhere in the genus in vailima.
