Diagnosis

Based on Vasconcelos & Ferreira (2017), this species may be separated from other Charinus in eastern South America by means of the following combination of characters: median and lateral eyes well developed; male gonopods with processus internus and lateral lobe 1 forming several long lobes, lateral lobe 2 and dorsal lobe drop-shaped, with dorsal lobe larger than lateral lobe 2, and lamina medialis forceps-shaped; cheliceral claw with eight teeth; pedipalp femur with four or five dorsal spines and five ventral spines, patella with six dorsal spines and three or four ventral spines, and tibia with dorsal spine 2 two to three times as long as spine 1; leg IV distitibia with eighteen trichobothria, sc and sf series each with six trichobothria.

Etymology

Refers to Santana, the municipality in the Brazilian state of Bahia, in which the type locality is situated ( Vasconcelos & Ferreira 2017).

Type material

Holotype BRAZIL • 1 ♂; Bahia, Santana, Gruta do Padre ; 13°13′07.18″ S, 44°03′51.98″ W; 11 Jul. 2014; R.L. Ferreira leg.; ISLA 12777 [not examined].

Distribution

Known only from the type locality.

Natural history

Gruta do Padre Cave is one of the largest and best preserved caves in Brazil. The cave has three distinct levels and a river at the lowest level. The type specimens of C. santanensis were collected in a large chamber in the upper level, some 250 m from the entrance, on rock blocks covered by a shallow, moist layer of mud. Due to their proximity to the entrance of the cave and the lack of any troglomorphic characters, C. santanensis appears to be troglophilic, not troglobitic ( Vasconcelos & Ferreira 2017).
