Canthonella Chapinis a small genus of 16 species that occur in the West Indiesand South America(Ratcliffe and Smith 1999). Matthews (1965)observed them opportunistically feeding on bird, snail, and mammal dung, and the five specimensof Canthonella silphoides(Harold) taken in this study were collected in both dung and carrion traps( Table 1).
CryptocanthonBalthasar( Fig. 40) is another small genus with 35 species occurring from Mexicoto Brazil( Cook 2002). They inhabit the litter of lowland rainforests and montane cloud forests. Cryptocanthon peckorumHowden( Brazil, Colombia, Bolivia; Cook 2002) was col- lected in both dung (89%) and carrion traps (11%) at Reserva Ducke ( Table 1). DeltochilumEschscholtz( Figs. 41–43) is a New World genus with more than 80 species ( Gill 2002). Most species feed on carrion, but all five species taken at Reserva Ducke were also collected in the dung traps. Interestingly, the few specimens of Deltochilum orbiculareLansbergewere collected only in the dung traps. Deltochilum diringshofeni( Brazil)(61% on carrion) and D. septemstriatum( French Guiana, Brazil) (78% on carrion) were the two most abundant species of Deltochilumat Reserva Ducke ( Table 1).
ScybalocanthonMartínezhas approximately 19 species that occur in Central and South America ( Silva 2011). Molano Rendón and Medina Uribe (2010)reported Scybalocanthonspeciesare usually diurnal, and that they are known to feed on vertebrate dung preferentially but also on carrion and fungi. Scybalocanthon pygidialis(Schmidt)( Brazil, Colombia, Suriname) was collected from both dung (92%) and carrion traps (8%) at Reserva Ducke ( Table 1).
