roepkei sp. n.
The general coloration is a rufous brown rather than dark brown (kalisi),
the forewing with strongly curved, double, crenulate, fine antemedial and
postmedial fasciae in darker brown. The discal spot is diagnostically pale
and there are pale grey markings on the margin near the apex of the
forewing. The male genitalia are as described and distinguished from those
of kalisi in the generic account. The right valve consists of two slender
processes, the left of only one, equivalent to the lower one on the right.
