B e m e r k u n g e n: Diese Art fällt durch ihre stark irisierenden Elytren auf; am Pronotum sind allenfalls Spuren von hinteren Eindrücken zu ahnen. Der Aedoeagus des Männchens weicht von dem fast aller bisher bekannten Gattungsvertreter durch seine apikal gegabelten Parameren auf (Abb. 43). Beim Weibchen zeigt das 8. Sternit am Hinterrand eine flache Ausrandung ( Abb. 69 ).
