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

Diagnosis. Members of C. guama sp. nov. resembles those of C. chamarreta sp. nov. and C. alayoni by having a similar pattern on abdomen and carapace with a well-defined brown carapace pattern and a dorsally marked threelined light gray chevron pattern on the abdomen ( Figs 5C , 6C ), but males can be distinguished by the morphology of the embolus tip, where the embolus opening is apical, just at the tip ( Fig. 8C ) (sub-apical, closer to the base of the spine-like projection in C. chamarreta sp. nov.: Fig. 8A ); females with a triangular posterior receptacle, with anterior margins somewhat rounded distally ( Fig. 6E ).

Description. Male (holotype): Carapace brown with a dark brown pattern as in Fig. 5C . Chelicerae, palps, endites, labium, sternum and legs light grayish brown; femora, patellae, tibiae and metatarsi of legs with dark brown stains, palpal femora and tibiae also with dark brown stains; coxae and trochanters lighter; abdomen pale gray, with dark brown dorsal chevron pattern as in Fig. 5A ; anal tubercle and spinnerets lighter than abdomen. Total length 2.50. Carapace 0.90 long, 5.1 wide. Tegulum oval with embolus longer than tegulum width; embolus tip shape as Figs 5D , 8C , with a spine-like projection and the opening at the tip. Female (paratype MPEG 37305): Carapace brown with a dark brown pattern as in Fig. 6C . Chelicerae, palps, endites, labium, sternum, coxae, legs, abdomen, anal tubercle and spinnerets as in male. Total length 3.55. Carapace 1.50 long, 1.20 wide. External genital area with weakly sclerotized area ( Fig. 6D ). Internal genitalia with a triangular posterior receptacle, with rounded distally sclerotized margins ( Fig. 2E ) where sperm are stored during mating, and a short membranous uterus externus (presumed anterior receptacle) where fertilization occurs.

Distribution. Known only from localities in the municipality of Guamá in Cuba ( Fig. 9 ).
