Systematics of the New Zealand longicorn beetle genus Ophryops White (Coleoptera:Cerambycidae:Cerambycinae)

Abstract

The New Zealand longicorn beetle genus Ophryops White is revised. A diagnosis and redescription of Ophryops and a key to all species of the genus are given. Five species are redescribed: O. fuscicollis (Broun), O. dispar Sharp, O. aegrotus (Bates), O. medius (Broun), O. pallidus White, and one is described as new: O. pseudofuscicollis, sp. nov. Ophryops nigropictus Broun is synonymised with O. dispar; Didymocantha fuscicollis Broun is moved to Ophryops and its male is described for the first time. Terminalia of both sexes are illustrated and described for all species for the first time. The genus occurs in the North, South and Stewart Islands of New Zealand. Phylogenetic analysis shows that this genus is monophyletic and divided into two species-groups, the fuscicollis-group and the dispar-group.
