grisescens sp. n.
12-13mm. This is a slightly more grey brown species than those of
the olivescens group, the forewing more uniform within which the
fine, pale fasciae are more distinctive. The postmedial has a slightly more
acute angle, its costal part having a slight kink at its centre. The pale grey
subapical patch is also slightly more conspicuous. The reniform is larger than
allies and has a distal constriction that renders that side bilobed. The male
genitalia are very similar to those of olivescoides except
the blade-like process is apically falcate and the triangular one is narrower,
