Akhmetova, L.A. 2009. A review of scarabs of the subgenus Plagiogonus Mulsant, genus Aphodius Illiger (Coleoptera, Scarabaeidae), of the fauna of Russia and neighboring countries. Entomological Review, 89(4): 428-436.
Abstract—A review of the scarab subgenus Plagiogonus Mulsant, genus Aphodius Illiger, of the fauna of Russia and adjacent countries is given, with a key to the species and data on their distribution. Two species names, Aphodius reitteri D. Koshantschikow, 1894 and A. burgaltaicus Csiki, 1901, are restored from synonyms. Two new synonymies are established: A. chan Endrödi, 1967 = A. peregii Endrödi, 1983, syn. n.; A. reitteri D. Koshantschikow, 1894 = A. kricheldorffi W. Koschantschikov, 1910, syn. n. Neotype of A. culminarius Reitter, 1900 and lectotype of A. burgaltaicus are designated, and redescriptions of these species are given. A secondary sex character of Plagiogonus is found.
