New records of relictual populations of dung beetle species (Coleoptera, Scarabaeidae) in the Atlantic Forest of the Brazilian Northeast

Abstract

The diversity of dung beetles is still underestimated in northeastern Brazil. Recent collections have revealed new records of the following species: Canthon histrio (Lepeletier de Saint-Fargeau & Audinet-Serville, 1828), Coprophanaeus acrisius (MacLeay, 1819), Coprophanaeus dardanus (MacLeay, 1819), Deltochilum alpercata Silva et al., 2015, Deltochilum brasiliense (Castelnau, 1840), Dichotomius gilletti Valois et al., 2017, Dichotomius iannuzziae Valois et al., 2017, Eurysternus calligrammus Dalman, 1824, Eurysternus parallelus Castelnau, 1840, Oxysternon silenus Castelnau, 1840, and Phanaeus splendidulus (Fabricius, 1781). These records are discussed in light of the known biogeography of each species.
