Eurysternus Dalman, 1824

Notes

A Neotropical genus with 53 described species ( Génier 2009) that are mostly endocoprids ( Halffter and Matthews 1966, Cupello and Vaz-de-Mello 2018). Eurysternus species are easily collected in pitfalls baited with faeces, occurring in forests and frequently abundant in flooding-prone areas ( Génier 2009). Génier (2009) was used for species identification. Thirteen species were recorded in our surveys: Eurysternus arnaudi Génier, 2009, E. atrosericus Génier, 2009, E. balachowskyi Halffter & Halffter, 1977, E. caribaeus (Herbst, 1789), E. cavatus Génier 2009, E. cayannensis Castelnau, 1840, E. cyclops Génier, 2009, E. fallaciosus Génier, 2009, E. foedus Guérin-Méneville, 1844, E. hamaticollis Balthasar, 1939, E. hypocrita Balthasar, 1939, E. plebejus Harold, 1880 and E. wittmemorum Martínez, 1988 (Fig. 3 O-Q, Fig. 4 A-J).
