Bertula rufithorax sp. n.

Bertula rufithorax
Figure 66

15mm. The facies is somewhat similar to that of mesilau, except the forewing postmedial is less strongly biarcuate and less conspicuously paler. The reniform is lunulate, rather than semicircular, black-centred with only a weakly paler edging. The orbicular is present but smaller and more distant from the reniform. The antemedial is irregular, more basal than in mesilau, with the basal zone and thorax tinged dull rufous. The labial palps are of similar length, the third segment angled back from the second, but without the conspicuous hair pencil of mesilau. The male genitalia have a less robust uncus than in mesilau. The valves are shorter, entire, irregularly tapered and slightly upcurved. There is a quadrate, rugose projection at the base of the costal margin. The aedeagus vesica extends more dorsally and is not so diverticulate as in mesilau. It lacks a strong ventral cornutus, but has an oblique band of spines at the aedeagus apex.
