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

Diagnosis. Members of C. chamarreta sp. nov. resembles those of C. guama sp. nov. by having a similar pattern on abdomen and carapace ( Figs 1C View FIGURE 1 , 2C View FIGURE 2 ), but males can be distinguished by the morphology of the embolus tip, where the embolus opening is sub-apical, closer to the base of the spine-like projection ( Figs 1D View FIGURE 1 , 8A View FIGURE 8 ) (apical in C. guama sp. nov.: Fig.8C View FIGURE 8 ); females with a triangular posterior receptacle, with distally acute margins ( Fig. 2E View FIGURE 2 ).

Description. Male (holotype): Carapace brown with a dark brown pattern as in Fig. 1C View FIGURE 1 . Chelicerae, palps, endites, labium, sternum and legs light orangish brown ( Fig. 1B View FIGURE 1 ); femora, patellae and tibiae 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. 1A View FIGURE 1 ; anal tubercle and spinnerets lighter than abdomen. Total length 2.10. Carapace 0.60 long, 0.55 wide. Tegulum oval with embolus longer than tegulum width; with threepointed embolus tip as in Figs 1D View FIGURE 1 , 8A View FIGURE 8 , also with a spine-like projection and the embolus opening a little behind the tip, closer to the base of the spine-like projection. Female (paratype MPEG 37298): Carapace brown with a dark brown pattern as in Fig. 2C View FIGURE 2 . Chelicerae, palps, endites, labium, sternum, coxae, legs, abdomen, anal tubercle and spinnerets as in male. Total length 2.25. Carapace 0.65 long, 0.60 wide. External genital area with weakly sclerotized area ( Fig. 2D View FIGURE 2 ). Internal genitalia with a triangular posterior receptacle (where sperm are stored during mating), with sharp distally sclerotized margins ( Fig. 2E View FIGURE 2 ) and a short membranous uterus externus (presumed anterior receptacle), where fertilization occurs.
