Figures 7 , 8D , 9

Types. Holotype: male ( MPEG 37306 ) from Juan Gonzalez (19°57'55.2"N 75°59'38.7"W), Santiago de Cuba, Cuba, 10.VIII.2012, A. Sánchez-Ruiz leg., leaf litter.

Etymology. The specific name is a noun in apposition, referring to the small spinules at the tip of embolus that resembles a handsaw ( serrucho in Spanish language).

Diagnosis. Members of C. serrucho sp. nov. resembles those of C. juragua Sánchez-Ruiz, Platnick, Dupérré and C. glochidiosus sp. nov. by having a similar pattern on abdomen and carapace ( Fig. 7C ), but males can be distinguished by the morphology of the embolus tip ( Fig. 7D ) where the embolus has only one spine-like projection (instead of two in C. glochidiosus sp. n.: Fig. 8B ), as well as several lined up small spinules at the tip, resembling a handsaw ( Fig. 8D ).

Description. Male (holotype): Carapace orangish brown with a dark and poorly developed pattern as in Fig. 7C . Chelicerae, palps, endites, labium, sternum and legs light orangish 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. 3A ; anal tubercle and spinnerets lighter than abdomen. Total length 2.60. Carapace 0.80 long, 0.65 wide. Tegulum oval with embolus longer than tegulum width; embolus tip shape as Figs 7D , 8D ; with one long spine-like projection and several ordered small spinules at the tip that resembles a handsaw. Female unknow.

Distribution. Known only from the type locality in Cuba ( Fig. 9 ).
