Although initially described as a subgenus of Copris Geoffroy, 1762, Homocopris had long been treated as a junior synonym of Dichotomius Hope, 1838 (Martínez 1951) until it was reclassified as a distinct genus (Vaz-de-Mello et al. 2010). Herein, we revisit the taxonomy of Homocopris. In doing so: we describe two new species previously considered to represent the Brazilian population of Homocopris torulosus (Eschscholtz, 1822); revalidate Pinotus punctatissimus from synonymy under Homocopris torulosus and place it in Homocopris as had previously been done only informally (González et al. 2015; Rebolledo et al. 2017); recognize two new synonymies; and describe a new genus, Andinocopris gen. nov., which includes two former members of Homocopris. Presently, Homocopris includes four species: H. torulosus, H. punctatissimus (Curtis, 1845) comb. nov., H. grossiorum sp. nov. and H. williami sp. nov. Andinocopris includes A. achamas (Harold, 1867) gen. et comb. nov. and A. buckleyi (Waterhouse, 1891) gen. et comb. nov. Pinotus simulator Luederwaldt, 1936 is here considered a new junior synonym of Andinocopris buckleyi. An identification key to members of both genera is provided as well as images of diagnostic characters for all species. Finally, we discuss the placement of Andinocopris and Homocopris within Scarabaeinae and propose a new tribe, Homocoprini tribe nov., to include both genera.
