Natural History of Procinura aemula (Serpentes: Colubridae) From Chínipas, Chihuahua, Mexico

Spiders (Arachnida: Araneae) feeding on snakes (Reptilia: Squamata)

“…In the Sonoran Desert (North America), numerous species of small, fossorial snakes occur that feed heavily on small spiders (Babb et al 2005;Holm 2008;Smith et al 2008). In stomach and fecal samples of the ground snake (Sonora semiannulata), the remains of black widow spiders and small scorpions are commonly detected, implying that these types of venomous arachnids are habitually consumed by these snakes, apparently without harming them (Funk 1967;Degenhardt et al 2005).…”

Amphibians and reptiles of Yécora, Sonora and the Madrean Tropical Zone of the Sierra Madre Occidental in northwestern Mexico

“…Little is known of this species. However, it is conjectured to be a close relative of T. annulifera, which occurs in northern Sinaloa (Smith et al 2005).…”

“…One species, the snail-eating snake Tropidodipsas repleta (Figure 8), was described from a single specimen collected west of Mesa del Campanero (Smith et al 2005) and represents the northern-most member of a genus otherwise associated with the tropics. It has since been discovered near Chinipas, Chihuahua (Lemos and Smith 2007), but subsequent observations from the Yécora area are few.…”
