Bertula spineusalis sp.n.

Bertula spineusalis
Figure 77

16mm. The facies of the somewhat worn specimen appears to be as in phlegeusalis and erythrognatha. The antennae are bipectinate. However, the genitalia, though sharing the basic features of the phlegeusalis group, are markedly different. The uncus has a spatulate process dorso-subbasally that, when in situ, would be directed towards the anterior of the abdomen. The valves, though bifid, have the two processes more robust, the dorsal one triangular with a rounded apex and the ventral one much longer, sabre-like. The aedeagus and vesica have no distinctive spining though there is general scobination.
