Abstract
Knowledge on arthropod assemblages in the Brazilian semideciduous dry forest (caatinga) is scarce, despite the increasing exposure to degradation due to human activities such as logging and intensive agriculture. We performed a short-term survey on the diversity of scorpions in two types of caatinga (hipoxerophytic and hiperxerophytic) in Pernambuco State, Northeastern Brazil. A combination of active collection and pitfall traps was used to sample soil scorpions. Six species belonging to two families were registered: Bothriurus asper, Bothriurus rochai (Bothriuridae), Tityus stigmurus, Tityus pusillus, Rhopalurus rochai and Ananteris franckei (Buthidae). There was no significant difference in the richness and the abundance of scorpions in the two types of caatinga. Bothriurus asper was the most abundant species in both environments. Regarding constancy, all species were classified as accidental.
