Eugoa tessellata sp. n.

Eugoa tessellata (paratype)
(x 1.56)

11mm. The ground colour of both wings is pale creamy fawn. The forewing fasciation is typical but narrow, a dull dark brown, oblique, the antemedial angled centrally and the submarginal relatively well defined. The species is distinguished by longitudinal streaking of dark brown within the spaces between the veins. The hindwing can be shaded lightly with brown over the distal half, but one specimen has it completely brown. The genitalia have the ductus and bursa short as in basipuncta and obliquipuncta, with the bursa finely scobinate throughout, but the ductus is very much narrower, and there are no structures associated with the ostium.
