Immature stages and ecology of two species of the South African genus Stripsipher Gory & Percheron, 1833 (Coleoptera, Scarabaeidae, Cetoniinae, Trichiini)

Abstract

Based on the study of newly accessible type material, Stripsipher drakensbergi Ricchiardi, 1998, is demoted to a junior synonym of S. jansoni Péringuey, 1908. The genus Stripsipher Gory & Percheron, 1833, thus, currently includes 12 species, but for none of these are larval stages and/or pupae currently known. The immature stages of S. orientalis Ricchiardi, 2008 and S. jansoni are described here for the first time and updated observations on distribution and ecology of both species are provided. Morphological affinities of Stripsipher with other Trichiini larvae are presented and the main diagnostic differences discussed. The larvae of both species are very similar to those of other representatives of the tribe Trichiini, with key differences found on the epipharynx. Based on the morphology of larvae and adults, it is suggested that Stripsipher is a member of the clade composed of Valgini, Trichiini and Cryptodontini. Petr Šípek et al.
