Revision of the obligate mushroom‐feeding African “dung beetle” genus Coptorhina Hope (Coleoptera: Scarabaeidae: Scarabaeinae)

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.

Revision of the southern African genus Frankenbergerius Balthasar with description of new taxa (Coleoptera: Scarabaeidae: Scarabaeinae)

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.

A review of the scarab beetle tribe Aphodiini (Coleoptera, Scarabaeidae) of the fauna of Russia

An annotated list of 183 species of the dung-beetle tribe Aphodiini of the Russian fauna is given. The highest species diversity is characteristic of the southern mountainous regions of the country, the richest local faunas being known from the Lower Volga area. The greatest numbers of species are known from the steppe and broadleaved forest zones and from the nemoral types of altitudinal zonation of vegetation. The bulk of the fauna is formed by the species with wide ranges; 111 species occur in two or more landscape zones or altitudinal zonation types. Six groups of faunistically similar zoogeographic provinces are distinguished within the territory of Russia.

Diagnosis, Classification, and Phylogenetic Relationships of the Orphnine Scarab Beetles (Coleoptera, Scarabaeidae: Orphninae)

Orphnine scarab beetles (Orphninae) are widely distributed in the tropical and subtropical regions of the southern continents except for Australia. The catalogue of nominal taxa of orphnines includes 2 tribes, 15 genera, and 195 species. Diagnosis of the group, based on adult morphological characters, is as follows: antennae 10-segmented with 3-segmented club; mandibles with 2–4 scissorial teeth and well developed mola; labrum and mandibles protruding past clypeus and visible from above; scutellum well developed in winged species, reduced but distinct in wingless species; wings with distinct anal area; apices of anterior tibia in males without spur but normally with a few robust setae; anterior coxa with longitudinal hollow on anterior surface; tarsi with 2 similar claws; middle and hind tibiae with 2 apical spurs; abdominal sternite 2 with sub-triangular to rounded plectrum; dorsal surface of hind coxae with oval flat stridulatory file; pygidium partly hidden under elytra; parameres symmetrical; bursa copulatrix sacciform, membranous; spermatheca C-shaped, not sclerotized; accessory vaginal glands developed; abdomen with 2 sclerotized tergites (VII–VIII) and 6 visible sternites (III–VIII). Preliminary phylogenetic analysis based on 47 characters of adult morphology shows that the tribe Aegidiini Paulian is a natural, monophyletic group. The genus Stenosternus Karsch described from a single specimen from São Tomé Island (Gulf of Guinea), is morphologically more similar to the New World taxa than to the Old World ones and is provisionally placed in Aegidiini. The tribe Orphnini Erichson seems non-monophyletic and has no synapomorphies. The genus Orphnus is apparently a polyphyletic group and it needs taxonomic revision. The hypothesis on sister-group relationship of Orphninae and Allidiostomatinae, based on molecular data, is not supported by the morphological characters. The stridulatory organs (the putative synapomorphy of Orphninae + Allidiostomatinae) are not identical in these groups; the mouthparts and female genitalia are essentially different. Orphninae have chewing mouthparts with large scissorial teeth and well developed mola, which is characteristic of generalist saprophagous species. Allidiostomatinae have mandibles with scissorial teeth and mola reduced; they also have sclerotized bursa copulatrix and sclerotized mandibular duct which opens on the dorsal side near condyle. Considering the present day development of alpha-taxonomy of most orphnine taxa, especially the speciose genus Orphnus, it seems premature to propose changes in higher classification of the subfamily. To clarify the phylogenetic position of the Orphninae among scarab beetles it is essential to include representative members of all taxa of orphnine lineage (sensu Browne, Scholtz, 1998) into the analysis.

Revision of the Madagascan genus Madecorphnus Paulian (Coleoptera: Scarabaeidae: Orphninae).

A scarab beetle genus, Madecorphnus Paulian, endemic to Madagascar, is revised. Nine new species are described: M. brunneus sp. nov., M. dentatus sp. nov., M. montreuili sp. nov., M. niger sp. nov., M. pauliani sp. nov., M. perinetensis sp. nov., M. peyrierasi sp. nov., M. punctatus sp. nov., M. simplex sp. nov. Diagnosis of the genus is clarified. Distribution map and a diagnostic key to all species are presented.

Rediscovery of the enigmatic Stenosternus costatus Karsch (Coleoptera: Scarabaeidae: Orphninae) from Sao Tome Island.

Stenosternus Karsch, 1881 is one of the least-known genera of the Orphninae scarab beetles. It was described from a single specimen of the odd-looking S. costatus Karsch, 1881, from the island of Sao Tome, Gulf of Guinea, West Africa. Karsch (1881) originally placed Stenosternus in the “Copridae” but later moved it to the Orphninae (Karsch, 1887). Since then, no more findings of S. costatus have been reported. The genus was redescribed by Frolov (2013) from the holotype of S. costatus and provisionally placed in the tribe Aegidiini Paulian based on a number of putative synapomorphies (Frolov, 2012). However, the material limited to only one male specimen did not allow the author to clarify which of its unique characters might be malformations or be sex dependent.

Revision of the genus Delopleurus Boheman (Coleoptera: Scarabaeidae: Scarabaeinae) with description of new species from Africa

The genus Delopleurus Erichson, 1847, is revised. Five new species are described from Africa: Delopleurus naviauxi sp. nov., Delopleurus krikkeni sp. nov., Delopleurus darrenmanni sp. nov., Delopleurus fossatus sp. nov. and Delopleurus pubescens sp. nov. One new synonymy is established (Delopleurus parvus (Sharp, 1875) = Delopleurus cardoni Paulian, 1934, syn. nov.). Lectotype of Delopleurus pullus Boheman, 1857, is designated. Delopleurus janssensi Frey, 1963, is transferred to the genus Metacatharsius Paulian, 1939. A key to the Delopleurus species and locality maps are given. http://zoobank.org/urn:lsid:zoobank.org:pub:67AE5CC5-9C9C-4872-A2B6-68C3BA82C44A

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

Abstract 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.

Revision of the southern African genus Macroderes Westwood (Coleoptera: Scarabaeidae: Scarabaeinae)

abstract The southern African genus Macroderes Westwood is revised. Six new species, M. amplior n. sp., M. minutus n. sp., M. endroedyi n. sp., M. namakwanus n. sp., M. foveatus n. sp., and M. cornutus n. sp., are described.The neotype of M. bias (Olivier) is designated.Two new synonymies are established: M. pilula Sharp is a junior synonym of M. bias (Olivier), and M. westwoodi Preudhomme de Borre is a junior synonym of M. undulatus Preudhomme de Borre. A key to species and notes on biology and distribution are given.

New scarab-beetle species (Coleoptera, Scarabaeidae, Aphodiinae, Orphninae) from Central Asia and Southern Africa

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.
