In this study, we revise the taxonomy of the endemic Mexican genus Ceratotrupes Jekel, 1865. It comprises three species, distributed in the Sierra Madre Occidental and Trans-Mexican Volcanic Belt (Ceratotrupes fronticornis (Erichson, 1847) and Ceratotrupes bolivari Halffter & Martínez, 1962), and the Sierra Madre del Sur (Ceratotrupes sturmi (Jekel, 1865)). We confirm C. mniszechi (Jekel, 1865) as a junior subjective synonym of C. sturmi. The examination of the holotype of C. sturmi and specimens recently collected in the Sierra Sur de Oaxaca (Oaxaca) and Omiltemi (Guerrero) allowed us to identify and describe a new species, Ceratotrupes gonzaloi sp. nov. from Omiltemi, Guerrero. We redescribe the morphology of C. sturmi and provide a diagnostic key to the four members of the genus Ceratotrupes. Photographs of the habitus and male genitalia of the four species, a distribution map, and observations on their ecology and biogeography are provided.
The Phanaeus endymion species group is defined as a lineage of dung beetles distributed from Mexico to Ecuador. The current arrangement of the P. endymion species group includes 18 species (five newly described and three revalidated herein): P. arletteae Arnaud, 2018; P. bravoensis Moctezuma, Sánchez-Huerta & Halffter, 2017; P. chiapanecus sp. nov.; P. edmondsi Moctezuma, Deloya & Halffter, 2019; P. endymion Harold, 1863; P. funereus Balthasar, 1939 stat. rev.; P. halffterorum Edmonds, 1979; P. huichol Moctezuma, Sánchez-Huerta & Halffter, 2017; P. jackenioi sp. nov.; P. malyi Arnaud, 2002; P. olsoufieffi Balthasar, 1939 stat. rev.; P. pacificus sp. nov.; P. panamensis sp. nov.; P. porioni Arnaud, 2001 stat. rev.; P. pyrois Bates, 1887; P. rzedowskii sp. nov.; P. zapotecus Edmonds, 2006; and P. zoque Moctezuma & Halffter, 2017. Phanaeus dionysius Kohlmann, Arriaga-Jiménez & Rös, 2018 syn. nov. is considered as a new junior subjective synonymy of P. zapotecus Edmonds, 2006. Phanaeus blanchardi Olsoufieff, 1924 and P. bothrus Blackwelder, 1944 are junior objective synonyms of P. olsoufieffi Balthasar, 1939 stat. rev.
