Troglorhopalurus araras (Scorpiones: Buthidae) a new subterranean scorpion from Chapada Diamantina, Bahia, Brazil

ABSTRACT

We describe Troglorhopalurus araras sp. n. based only on females, as a new obligatory and exclusively subterranean scorpion occurring in three caves from Ituaçu, State of Bahia, Brazil. The caves of Ituaçu belong to an isolated portion of the Una geomorphological group. Troglorhopalurus araras is the third known species of Troglorhopalurus and differs from its congeners by size, carination mainly in chela hand and metasoma, teeth of pecten, shape of telson spine, and colour. This new species enhances the diversity of cave-dwelling species in Brazilian caves, as well as the knowledge of cave scorpions. Troglorhopalurus araras must be considered threatened due to its restricted endemism at caves in the Chapada Diamantina.
