Taxonomic revision of Eunanus Ohaus, 1909 (Coleoptera: Scarabaeidae), with first records and two new species from Brazil

AbstractEunanus Ohaus, 1909 has so far been known exclusively from Argentina and Paraguay, with only two described species: E. murinus Ohaus, 1909 and E. podtiaguini Gutiérrez, 1951. Here, the genus is revised and redefined, and two new species are described from Brazil: Eunanus kozlovi sp. nov., from Mato Grosso do Sul state, and Eunanus valmorbidai sp. nov., from Rio Grande do Sul state. Furthermore, Leucothyreus beckeri (Martínez, 1964) is transferred to the genus under the new combination Eunanus beckeri (Martínez, 1964) comb. nov. The lectotype of E. murinus Ohaus, 1909 is designated, and an identification key to all the species and a distribution map are provided.
