Nycteola sinuosa Moore
Symitha sinuosa Moore, 1888, Descr. new Indian lepid. Insects Colln W.S. Atkinson: 289.


Nycteola sinuosa

The forewings are a more ashy grey than in the previous two species, with more distinct fasciation, the double postmedial and antemedial ones arising in an oblique (acute angle distad) manner from the costa before becoming irregularly transverse. The hindwings grade whiter towards the base.

Taxonomic note.
Sundanian material may differ slightly in male genitalia from typical Indian material. The Bornean specimen has a much more expanded tegumen, a more elongate uncus, an elongate central distal process of the valve that is twice as long and also a distinct row of carinae on the exterior of the valve. There is also a row of more robust but small cornuti in the aedeagus vesica.

Geographical range. India, Hong Kong; Peninsular Malaysia, Java, Borneo.

Habitat preference.
A single male has been taken in upper montane forest at 1775m on Bukit Monkobo in Sabah.

Typical Indian sinuosa has a pale green larva with a yellow head that feeds on Pterocarya (Juglandaceae) (Gardner, 1948).
