Eugoa aridoides Holloway sp. n.

Diagnosis

♂♂, ♀♀ 7-8mm. This is a paler, browner species than clavata but has similar fasciation to the forewing. However, the black discal spot is much larger and is elongated basad by a black streak, sometimes detached from the spot itself. In this feature it is similar to arida van Eecke (Sumatra, Java) where there is a large, rather elliptical black spot (seen also in two specimens of aridoides). The male antennae are ciliate. The male genitalia are very similar to those of arida, but the valve saccular process is just shorter than the valve itself, rather than just longer, and not so strongly flexed dorsally over its apical portion. The aedeagus vesica contains three or four robust cornuti rather than a large cluster of more slender ones. The female genitalia resemble those of clavata, but there are no lateral pockets on the seventh segment.
