calcaurea sp. n.
, 15-18mm. This is a slightly larger species than coelonota,
distinguished by the more extensive reflective golden areas on the forewing;
these do not show significant sexual dimorphism in their extent. Particular
features relative to coelonota are much broader blocks near the tornus and
subbasally on the costa. In the male genitalia, the distal process of the valves
appressed to the apex is singular, more digitate, straight, and the interior
saccular process is larger and more robust than in coelonota.
The aedeagus is very much larger and has a thorn-like spine at the apex. The
vesica is also larger with a longer distal diverticulum that is much more
coarsely spined over its apex. In the female, the eighth segment, ductus and
bursa are all more elongate, the ductus narrower and
bursa more pyriform and therefore distinctly broader.
