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.
