D e s c r i p t i o n o f f e m a l e ( Fig. 48 View Figs 44-48 ).

D i f f e r e n t i a l d i a g n o s i s. Differsfromtheotherspecieswithsetoseelytra and black tarsi described below by the absence of lateral strongly contrasting yellow spots on the elytra, and in the male by the triangularly notched clypeus and the narrow, transverse labrum.

D i s t r i b u t i o n a n d b i o l o g y. Known from central New Caledonia only.

E t y m o l o g y. The name is referring to the type locality, Col d’Amieu.
