Description of three new species of Paratrichius Janson, 1881 from China and revision of the distribution range of Paratrichius rubrodecoratus (Tesar, 1952) (Coleoptera: Scarabaeidae: Cetoniinae: Trichiini).

Three new species belonging to the genus Paratrichius Janson, 1881 (Paratrichius adornatus Ricchiardi, new species, Paratrichius tergorufus Ricchiardi, new species, and Paratrichius zonatus Ricchiardi, new species) are described from mainland China, and the distribution range of Paratrichius rubrodecoratus (Tesar, 1952) is clarified and updated.

A taxonomy review of Oreoderus Burmeister, 1842 from China with a geometric morphometric evaluation (Coleoptera, Scarabaeidae, Valgini).

The species of the genus Oreoderus are morphologically similar, and can be challenging to distinguish without dissecting the male genitalia. In this study, the Oreoderus species from China are reviewed. Three new species of Oreoderus are described: Oreoderus dasystibialis Li & Yang, sp. n., Oreoderus brevitarsus Li & Yang, sp. n. and Oreoderus oblongus Li & Yang, sp. n. A key of the male Oreoderus and a distribution map are provided. Oreoderus coomani Paulian, 1961 was found as a new record in China. The first description of the female of Oreoderus arrowi Ricchiardi, 2001 is provided. Oreoderus humeralis Gestro, 1891, Oreoderus quadricarinatus Arrow, 1944, Oreoderus crassipes Arrow, 1944, and Oreoderus momeitensis Arrow, 1910 are excluded from the Chinese fauna. Furthermore, we utilize geometric morphometric approaches (GM) to analyze the shape variation of four characters (pronotum, elytra, protibia and aedeagus) in Oreoderus. The morphological variations of Oreoderus and the taxonomic value of each character are discussed. The combined analysis of geometric morphometrics and comparative morphology support recognition of the three new species.

New species of Eriopeltastes Burmeister & Schaum, 1840 (Coleoptera, Scarabaeidae, Cetoniinae, Trichiini) from South Africa.

Both male and female of a new species of Eriopeltasttes Burmeister & Schaum, 1840, E. (E.) ornatus Ricchiardi, sp. n., are described from the mistbelt grassland of KwaZulu-Natal. Sexual dimorphism is extreme in this genus, with females being brachypterous, fossorial and entirely black to dark brown in general body colour. This is only the fifth out of 12 known species in this genus for which the female is known. The species appears to be restricted to areas within or in the immediate vicinities of two marginal nature reserves, Karkloof and Blinkwater, in a grassland habitat that is regarded as one of the most threatened in the Province of KwaZulu-Natal. Despite its acknowledged importance as centre of endemism the area is currently in a precarious state of large-scale degradation.

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

Based on the study of newly accessible type material, Stripsipher drakensbergi Ricchiardi, 1998, is demoted to a junior synonym of Stripsipher 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 Stripsipher orientalis Ricchiardi, 2008 and Stripsipher 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.
