Avatha tepescoides sp. n.
Athyrma tepescens Walker sensu Holloway, 1976: 34, partim.


, 23-25mm.
See the previous species, which tepescoides resembles very closely in facies, but is slightly smaller (cf. 25-27mm). The ground colour of tepescoides is slightly darker and more uniform than in tepescens. The outer border of the antemedial black band is straight to convex rather than slightly concave and less oblique; the inner border is more angled. The postmedial hieroglyph is smaller, and the course of the postmedial posterior to it curves more closely to the antemedial band. In the male genitalia the valve is distally more rounded, less triangular (in tepescens the apex is produced and the margin on the dorsal side elongate and slightly concave). The major diverticulum of the aedeagus vesica is shorter, with acute, rather than clubbed, cornuti at its apex. The female has the bursa shorter and broader, particularly at its base.
