Himantoides
Male: Frons slightly crested; lateral scales forming a kind of eyebrow. Palps rounded in dorsal and lateral view, ascending above eye, closely appressed to head. Antenna very long, reaching beyond fork Rs3-Rs4 of forewing; filiform; apical flagellomere about three times as long as broad. Foretibia externally and hindtibia above and below with long scaling; hindbasitarsal segment also with long scales. Forewing tornus obtuse, not projecting backwards. Hindwing M3 and CuA1 shortly stalked. Median anal tuft of abdomen smooth, truncate, conical, not fan-like; ventro-lateral scales prolonged to two rather thin but prominent tufts. Spines along edges of abdominal tergites elongate, only two rows present; scales on ventral edges of abdominal tergites prolonged, especially in the male.
Female: Antenna slightly incrassate before the long and gradually tapering hook. Abdominal sternite 7 transverse, short, apical edge straight and entirely spinulose.
Male genitalia: Uncus and gnathos simple, undivided, narrow, long, bent downward, forming an obtuse angle with the rather elongate tegumen. Uncus obtuse apically, slightly hooked in lateral view. Gnathos resembling that of Aleuron chloroptera; longer than uncus, narrow, produced into a thin point that curves downward, upperside of gnathos concave, the groove gradually narrowing distally, not extending to the end of gnathos, edges of groove somewhat dilated triangularly beyond the middle. Valve long, narrow, with almost parallel sides, upcurved, apically rounded; costa with very long scaling proximally; inner surface densely clothed with long stiff hairs. Harpe short, ending in a short slender and slightly clubbed process. Phallus with a spatulate, densely dentate process.
Female genitalia: Sterigma feebly sclerotized except at edges, triangular, short.
Rothschild & Jordan (1903: 413; 1465) reported that a faint angular projection on the end of the left edge of the gnathos was a remnant of the aborted left half of the gnathos. This is incorrect; there is a projection on both sides of the gnathos, which is symmetrical.
