Scarabaeinae View in CoL : Canthonini

Canthon ( Figs. 38–39 View Figs ) consists of about 150 species found from Canada to Argentina ( Gill 2002). Three species of Canthon were taken at Reserva Ducke, with C. triangularis being the most abundant ( Table 1). Canthon triangularis ( Fig. 39 View Figs , frontispiece) (Amazonian parts of Brazil, Suriname, French Guiana, Colombia, Bolivia) is diurnal, often seen resting on leaves, and is a dung roller; it represented 85% of all Canthon collected in the dung traps and 15% taken in the carrion traps.

Canthonella Chapin is a small genus of 16 species that occur in the West Indies and South America (Ratcliffe and Smith 1999). Matthews (1965) observed them opportunistically feeding on bird, snail, and mammal dung, and the five specimens of Canthonella silphoides (Harold) taken in this study were collected in both dung and carrion traps ( Table 1).

Cryptocanthon Balthasar View in CoL ( Fig. 40 View Figs ) is another small genus with 35 species occurring from Mexico to Brazil ( Cook 2002). They inhabit the litter of lowland rainforests and montane cloud forests. Cryptocanthon peckorum Howden View in CoL ( Brazil, Colombia, Bolivia; Cook 2002) was col- lected in both dung (89%) and carrion traps (11%) at Reserva Ducke ( Table 1).

Deltochilum Eschscholtz View in CoL ( Figs. 41–43 View Figs ) 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 orbiculare Lansberge View in CoL were collected only in the dung traps. Deltochilum diringshofeni ( Brazil) View in CoL (61% on carrion) and D. septemstriatum View in CoL ( French Guiana, Brazil) (78% on carrion) were the two most abundant species of Deltochilum View in CoL at Reserva Ducke ( Table 1).

Scybalocanthon Martínez has approximately 19 species that occur in Central and South America ( Silva 2011). Molano Rendón and Medina Uribe (2010) reported Scybalocanthon species are 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).
