A contribution to the study of the Lower Volga center of scarab beetle diversity in Russia: checklist of the tribe Aphodiini (Coleoptera, Scarabaeidae) of Dosang environs. Biodiversity Data Journal, 1: e979.

The field sampling of the Aphodiini scarab beetles in Dosang environs (Astrakhan Province, European Russia) in 2006–2012 resulted in the collection of 44 species. All but one of them belong to Aphodius Hellwig ( sensu lato). This is apparently the richest recorded local Aphodiini fauna in Russia. The high Aphodiini diversity in the area can be explained by the long vegetative season with high effective heat sum, large livestock providing abundant food resources throughout the year, and location in the transition belt between Volga-Akhtuba Floodplain and Desert floristic districts. The core fauna consists of mesophilous species widely distributed in the Palearctic region and confined to the intrazonal habitats. Other species have ranges mostly limited to the steppe, semidesert, and desert zones.

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.

Abstract. Third-instar larva of Aphodius bimaculatus (Laxmann) is described from the material collected in Belarus and compared with other known larvae of the subgenus Aphodius. The larva differs from other species in having convex clypeus with complex sculpture and in colour of the head.

Abstract — A new genus, Renorphnus gen. n, is established for Madagascar species Orphnus clementi Petrovitz. The new genus differs in distinctive shape of anterior tibiae of male, shape of clypeus, pronotum with 2 more or less prominent tubercles in both sexes, and in widened and pectinate setae on costal margin of wings. O. clementi is redescribed. Diagnostic key to Madagascar Orphninae genera is given.

Morphological descriptions and illustrations are presented for third-instar larvae of two species of the scarab beetle genus Aphodius Illiger: Aphodius (Heptaulacus) sus (Herbst) and A. (Chilothorax) variicolor Koshantschikov. These descriptions are based on material collected in European Russia. Larvae were collected from the soil with no association to dung although the adults of the same species normally occur in horse dung. Characters of the larvae are compared with those of described larvae of other species.

Revision of the Afrotropical dung beetle genus Sarophorus

The genus Sarophorus Erichson is revised. Six new species, S. bidentatus sp. n., S. punctatus sp. n., S. carinatus sp. n., S. striatus sp. n., S. latus sp. n., and S. nitidus sp. n., are described. A key to the species is given. Two species-groups are established.

Revision of the southern African genus Frankenbergerius Balthasar with description of new taxa

The southern African genus Frankenbergerius Balthasar is revised. Two new species, F. opacus sp. n. and F. nitidus sp. n. (South Africa, Western Cape), and one new subspecies, F. armatus tuberculatus ssp. n. (South Africa, Mpumalanga), are described. F. imitativus (Péringuey) is considered a junior synonym of F. forcipatus (Harold). A key to the species and notes on biology are given.
