Diagnosis. Males are similar to those of C. lavras by having a very short embolus, but can be distinguished by more rectangular RTA and the median apophysis with a small acute projection on the concave margin ( Fig. 17B–D ) (bifid RTA and smooth concave margin of median apophysis in C. lavras , Fig. 16D–E ). Females are similar to those of C. armasi by having an elongate median plate in the epigyne, but can be distinguished by having a wider median plate, and larger, deeper lateral depressions ( Figs 17I , 18C , 26E–F ) (narrower plate, smaller lateral depressions in C. armasi , Figs 19G–H , 26A–B ).

Types. Male holotype and female paratype from Cave S 1-MMC012 (20°26’41.81”S 45°36’1.80”W) [-20.44495, -45.6005], Pains , Minas Gerais, Brazil, 01.VIII.2022, Equipe Spelayon coll., deposited in IBSP 289712 .

Etymology. The specific name is a noun in apposition taken from the type locality.
