Figs 1 , 19–20 , 26A–B , 27

Diagnosis. Males are similar to those of C. marambaia by having a retrobasal cymbial horn, but can be distinguished by the thicker, shorter median apophysis, the slightly shorter embolus and by lacking a dorso-basal projection of the cymbium ( Figs 19B–D , 20C–F ) (long and thin median apophysis, longer embolus, dorso-basal projection in C. marambaia , Fig2 21C–E , 22B–F ). Females are similar to those of C. pains by having an elongate median plate in the epigyne, but can be distinguished by having a narrower median plate, and smaller lateral depressions ( Figs 19G–H , 26A–B ) (slightly wider median plate and larger depressions in C. pains , Figs 17I , 26E–F ).

Types. Male holotype and female paratype from Área de Relevante Interesse Ecológica ( ARIE) Floresta da Cicuta (22°32’53”S 44°05’34”W) [-22.54806, -44.09278], Volta Redonda, Rio de Janeiro, Brazil, 2.X.2003, E.F.
