Deltoplastis straminicornis

Deltoplastis straminicornis is a moth in the family Lecithoceridae. It was described by Edward Meyrick in 1910. It is found in Sri Lanka.[1]

The wingspan is 18–20 mm. The forewings are rather dark purple fuscous, in males somewhat mixed with pale ochreous suffusion towards the costal area between one-fourth and three-fourths. There is a triangular blackish-fuscous blotch obscurely edged with pale ochreous, extending on the dorsum from one-fourth to the middle, and reaching three-fourths across the wing. An indistinct small oblique blackish-fuscous mark is found on the middle of the costa and a narrow transverse blackish-fuscous spot on the transverse vein, obscurely pale edged, the upper end enlarged. There is an indistinct slender pale ochreous line from five-sixths of the costa to the dorsum before the tornus, preceded by an undefined fascia of blackish-fuscous suffusion dilated in the disc so as to reach the preceding spot. The hindwings are fuscous.[2]
