A new species-group of Ottistira Pascoe from New Guinea (Coleoptera : Curculionidae : Entiminae : Ottistirini)

Abstract

Nine new species of Ottistira Pascoe (O. arfakensis Riedel, O. ascendens Riedel, O. dani Riedel, O. longispina Riedel, O. obrienorum Riedel, O. paniaiensis Riedel, O. robusta Riedel, O. telefominensis Riedel, O. tumidirostris Riedel) are described from the highlands of New Guinea. They form a monophyletic group and can be diagnosed by their possession of both lateral humeral flanges and median elytral spines. Male genitalia offer good characters for separation of species, especially when the endophallus is everted. A key to the species is included. Habitus photographs and illustrations of male and female genitalia for all species are provided.
