This genus currently embraces a large number of species from both the
Old and New World tropics and subtropics and Australasia. It is probably
paraphyletic and has general zeuzerine characters of venation (Fig. 5),
partially bipectinate male antennae, and male genitalia with a simple valve,
broad uncus, and an aedeagus with the apex deeply divided into dorsal and
ventral ‘jaws'.

Venation of Xyleutes lutescens

There is great variety in forewing pattern as can be seen from the
Bornean species illustrated here. No doubt a modern revision of the world fauna
will establish subdivisions of the current genus, some of which will merit full
generic status; many genus-group names are available, such as those of Houlbert
listed above.
