Revision of Euspilotus, subgenus Platysaprinus, with description of two new species (Coleoptera: Histeridae)

The Neotropical subgenus Platysaprinus Bickhardt, 1916 of the genus Euspilotus Lewis, 1907 is revised, keyed and figured. Saprinus myrmecophilus Bickhardt, 1910, is newly transferred into genus Euspilotus Lewis, 1907, subgenus Platysaprinus Bickhardt, 1916. Euspilotus (Platysaprinus) carinipennis (Desbordes, 1924), is newly synonymized with Euspilotus (Platysaprinus) myrmecophilus (Bickhardt, 1910) syn. nov., based on examination of the type material. Two new species: Euspilotus (Platysaprinus) ferreri sp. nov. from Brazil (Minas Gerais, Mato Grosso and Rio de Janeiro) and Euspilotus (Platysaprinus) vazdemelloi sp. nov. from Brazil (Mato Grosso) are described. Euspilotus (Platysaprinus) latimanus (Schmidt, 1890) is newly reported from Argentina (Misiones), Paraguay (Amambay) and Bolivia. Lectotypes and paralectotypes of Saprinus latimanus Schmidt, 1890 are designated.
