Genus Schrankia Huebner, 1825 Figs 3, 8

Pyralis taenialis Hübner, [1809]. Type-species.

Remarks.

The genus Schrankia is characterized by the slender body and narrow, weakly sclerotized wings, light-brown ground color of the forewing and abdomen, long, straight labial palps, which are three to four times as long as the diameter of the eye (Zimmerman 1958) and the absence of ocelli. In the male genitalia (Fig. 8), uncus long, slightly curved; valva elongated with acute apex, bearing three well-developed processes in the middle; juxta X-shaped, composed of two well-sclerotized, bent bars; aedeagus thin, elongated, slightly curved with club-like caecum. The externally often confusingly similar species of the genus Hypenodes (type-species Hypenodes humidalis Doubleday, 1850) have a smaller and thinner body, narrow wings, grey or brownish forewing ground color, upcurved labial palps; ocelli also are absent. The configuration of the male genitalia is very uniform throughout the genus, having a very simple, long, narrow valva with small and thin processes at the base, and a short, wide aedeagus with a tapered caecum.
