Euphiuche Gen. n.

Type species: picta Moore.

Euphiuche is a manuscript name of Hampson that is applied in the BMNH curation to the species discussed at the end of this section. Lödl (1999e) listed picta under this name and related it (Lödl, 1999c) to apoblepta Turner comb. n. (see below). He suggested both might be more distinctly related to Acidon and Hiaspis.

The general appearance is similar to that of some Hypena species but the facies is much more colourful, with the half of the forewing up to the transverse medial boundary being a distinct rufous orange. The boundary is sharp, slightly sinuous, and basal to a flattish white discal lunule that is enclosed finely in black and then more diffusely in white again. The anterior end of this lunule is pulled out along one or more of the veins (usually R5) towards the margin for a short distance. The hindwing is uniform brown in the type species but yellow or white with a dark border in the others. The labial palps are more elongate, slender and upcurved than in Hypena.

The male antennae are fasciculate, the bristles at least twice as long as the breadth of the flagellum. The male abdomen has the eighth sternite with a weak framed corematous structure, but the triangular apodemes of the sternite are well separated and very slightly turned in to each other rather than splayed. The genitalia have features in common with Hypena, such as the small, angled aedeagus with apical scobination and the simple valves with a central pleat. However, the uncus is distinctive, being long and slender, apically acute and curved downwards, but with a subapical, dorsal knob that bears one or more moderate spines that overlie the apex.

The female genitalia of the type species have a very short ductus on which is set in slight asymmetry a very long, narrow corpus bursae that is swollen subbasally and distally with a narrow basal section and a gently constricted section between the two swellings. There is a scobinate signum in the centre of the more distal swelling. In apoblepta there is a similarly long corpus bursae but it expands gently from base to apex with a signum in a similar position.

Apart from the type species, the genus includes E. apoblepta Turner comb. n. (Queensland, New Guinea, Seram) and two undescribed species, one in the Bismarck Is. (slide Hypen. 40b) and the other (slide 19904) found in Java, Bali, Sumbawa, Timor and Sulawesi.
