Canthidium Erichson, 1847

Notes

This is one of the most diverse dung beetle genera, comprising around 180 described species ( Génier and Cupello 2018, Schoolmeesters 2022). Numerous species were described in small revisions, synopses and regional studies (e.g. Boucomont (1928), Balthasar (1939), Martínez et al. (1964), Howden and Young (1981), Solis and Kohlmann (2004), Kohlmann and Solís (2006)), while new species are expected to be described ( Cupello 2018, Kohlmann et al. 2018, Santana et al. 2019). Canthidium species have been recorded within Neotropical forests and intra-Amazonian savannahs (e.g. França et al. (2016)). Although little is known about most species’ habits, specimens are easily collected in traps baited with faeces, rotten fruit and/or light traps (e.g. Medri and Lopes (2001), Silva and Audino (2011), Silva et al. (2014)), while some species were observed feeding on fungus ( Falqueto et al. 2005). The specimens were identified from comparison with the original types and descriptions, which were analysed by one of the authors. Two species were identified to the species level in our survey in FLONA Tapajós: Canthidium deyrollei Harold, 1867 and C. melanocephalum (Olivier, 1789) (Fig. 2 H-I). Other 22 species are present, but could not be identified.
