Figs 21–22 , 27

Diagnosis. Males are similar to those of C. armasi by having a retrobasal cymbial horn, but can be distinguished by having a more elongate median apophysis, the slightly longer embolus, with sulcated embolus tip, and presence of the thick bent macroseta on the dorsum of the male palpal tibia ( Figs 21C–E , 22B–D ) (shorter embolus and thicker median apophysis with mesal tooth in C. armasi , Fig. 20F ).

Types. Male holotype from Ilha da Marambaia [-23.0688, -43.9186], Rio de Janeiro, Rio de Janeiro, Brazil, II.1985, no coll. ( IBSP 345213 ). Paratype: 1 male, with same locality of holotype, X–XI.1992, R . Xerez et al. coll. ( IBSP 345214 ) .

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

Description. Male (holotype). Carapace and legs yellowish orange. Chelicerae yellow, with four retromarginal teeth ( Fig. 22A ). Labium, endites and sternum cream. Opisthosoma grayish cream. Total length 5.3. Carapace 2.6 long, 2.0 wide. Clypeus 0.06 high. Eye diameters and interdistances: AME 0.04, ALE 0.08, PME 0.08, PLE 0.08, AME–AME 0.02, AME–ALE 0.02, PME–PME 0.04, PME–PLE 0.04, ALE–PLE 0.02, AME–PME 0.04. Leg measurements: I: femur 2.3/ patella 1.1/ tibia 2.1/ metatarsus 1.8/ tarsus 1.1/ total 8.4; II: 2.0/0.9/1.8/1.6/0.9/7.2; III: 1.8/0.7/1.3/2.0/1.0/6.8; IV: 2.5/1.0/2.2/2.9/1.0/9.6. Leg formula: 4123. Leg spination follows the genus pattern, except: tibia I–II v2-2-2-2; III v2-2-2; IV v2-2-2, p1-1-1, r1-1-1. Palp: RTA relatively simple, projecting forwards ( Figs 21D , 22C ); cymbium with retrobasal rounded horn, and inconspicuous dorso-basal projection; median apophysis slender; tegulum with membranous tegular process near the base of embolus ( Figs 21C–E , 22B–D ).

Female. Unknown.

Variation. Six males: total length 4.0–5.2; carapace 1.6–2.6; femur I 1.7–2.1.
