New scarab-beetle species (Coleoptera, Scarabaeidae, Aphodiinae, Orphninae) from Central Asia and Southern Africa. Entomological Review, 89(6): 685-688.

Abstract—Three new scarab-beetle species are described. Aphodius moronensis sp. n. (northern Mongolia) and A. kozlovi sp. n (eastern Tibet) with modified spurs on fore tibiae in males are placed in the falcispinis group of the subgenus Agolius but are similar to the grafi group of the subgenus Chilothorax in the shape of parameres and elytral pattern. The new species differ from A. falcispinis in the shape of the spur; A. moronensis sp. n. also differs in the shape of the body and parameres. Orphnus transvaalensis sp. n. is the second apterous Orphnus species found in Southern Africa. It differs from the closely related O. harrisoni in the shape of parameres, position of the hornlike clypeal process, and in a smaller body size.

New and little known species of Orphnus from the East African Rift

FIGURES 1, 2. Orphnus, habitus of male. Fig. 1—O. planicollis. Fig. 2—O. demeyeri, holotypeFrolov, A.V. 2013. New and little known species of the genus Orphnus MacLeay (Coleoptera: Scarabaeidae: Orphninae) from the East African Rift. Zootaxa, 3710(3): 297-300.

The East African Rift, especially Eastern Arc Mountains, are renown for exceptionally high biodiversity and endemism (Olson & Dinerstein 1998, Burgess et al. 2007). About 20 species of the scarab beetle genus Orphnus MacLeay, 1819 (Coleoptera: Scarabaeidae: Orphninae) were described or recorded from this region (Paulian 1948, Petrovitz 1971) but many of them are still known only from the type series. Orphnus planicollis Petrovitz, 1971, was described from a single male specimen from “Nyassa-Land” with no additional data about this species published until now. Examination of the Orphninae material housed in European museums revealed additional specimens from southern Eastern Arc Mountains...

Revision of the genus Adorodocia endemic to Madagascar

Montreuil, O., Frolov, A.V. 2014. Revision of the genus Adorodocia Brenske 1893 (Coleoptera: Scarabaeoidea: Rutelinae: Adoretini) endemic to Madagascar. Annales de la Société entomologique de France (NS), 49(4): 460-475.

The Adoretini of the Malagasy endemic genus Adorodocia Brenske 1893 is revised. Fourteen new species and  one  new subspecies are described and  compared with their most closely related species: A. constricta  n.  sp., A. cuccodoroi n. sp., A. flava n. sp., A. liliae n. sp., A. marginata n. sp., A. peyrierasi n. sp., A. pseudoconstricta n. sp., A. pseudoflava n. sp., A. pseudostrigata  n. sp., A. recta  n. sp., A. robusta  n. sp., A. sogai n. sp., A. vadoni n. sp., A. viettei n. sp. and A. vittaticollis flavipes n. ssp. The synonymy between Adoretus strigatus Waterhouse 1878, and Pseudadorodocia  aenigma Arrow 1901, is confirmed. Thus, based on the results of this study, the genus Adorodocia includes 16 species, and one of them is represented by two subspecies. Diagnostic characters to separate the species in the genus deal mostly with the shape of parameres, color of body and legs, shape of pronotum and female eighth tergite, setation of pronotum and elytra. Key to species, diagnoses and distribution for each species are provided. Endophallus and female genitalia are illustrated for the first time for this genus.

Abstract. Three new species of the scarab beetle genus Madecorphnus, endemic to Madagascar, are described from the material collected by the staff of the California Academy of Sciences. The new species are: M. fisheri sp. nov. (mid-elevation rain forest on the eastern flank of the Anosyenne Mountains, southern Madagascar), M. saintemariensis sp. nov. (coastal forest, Sainte Marie Island, eastern Madagascar), and M. tuberculatus sp. nov. (low elevation rain forest, Betampona Reserve, eastern Madagascar).

A review of Chilothorax of Mongolia

The Mongolian species of Aphodius Illiger belonging  to the  subgenus  Chilothorax  Motschulsky are    reviewed.  A. kerzhneri  Nikolajev and A. mongolaltaicus Nikolajev are placed in the subgenus Chilothorax. Two new synonyms (A. altaicus Nikolajev = A. puntsagdulamae Nikolajev, syn. n.; A. grafi Reitter = A. boreomongolicus Nikolajev, syn. n.) are established. Three new species are described. A key to Mongolian species of Chilothorax is presented.

The African genus Coptorhina Hope is revised. Nine new synonymies are established which reduces the number of valid names from 15 to six. One new species is also described. The name changes are the following: C. subaenea Janssens, C. bicolor Ancey, C. pygmaea Balthasar, and C. saganicola Müller are considered junior synonyms of C. nitidipennis Boheman; C. africana Hope, C. vicina Péringuey, C. obtusicornis Boheman, C. punctata Ferreira and C. optata Péringuey are considered junior synonyms of C. klugii Hope. The new species, C. excavata sp. n., is described from southern Africa. A key to the species and notes on biology are given.
