Bertula waterstradti sp.n.

Bertula waterstradti
Figure 125

15mm, 16mm. The male antennae are strongly bipectinate, but the labial palps are damaged in the specimen of this sex, and the genitalia have been broken off. The facies is somewhat similar to that of willotti except the forewing band is much broader, darker, with a general dull greenish tone, defined distally by a more oblique and distal postmedial that is generally sinuous, but most strongly so centrally. There is a faintly paler, obtusely angled postmedial evident over the posterior half of the hindwing. The ostium of the female genitalia is broad, crinkled, narrowing into a relatively long, slender, sclerotised ductus bursae. The corpus bursae is elongate, slightly pyriform, with two signa centrally, one a scobinate dome, the other a small, somewhat drop-shaped spine.
