Sánchez-Ruiz leg ., under rock, 1♀ ( MPEG 37302 ) Etymology . The specific name refers to the small spinules at the tip of embolus that resembles the glochids, a barbed bristle on the areole of some cacti. FIGURE 3 . Cubanops glochidiosus sp. nov. , holotype male (MPEG 37301). A Habitus, dorsal view. B Habitus, ventral view. C Carapace, dorsal view. D Left palp, in square a detail of the embolus tip, prolateral view. E Left palp, retrolateral view. Scale bars: A‒B: 0.5 mm, C‒E: 0.2 mm. Diagnosis . Members of C. glochidiosus sp. nov. resembles those of C. juragua Sánchez-Ruiz, Platnick & Dupérré and C. serrucho sp. nov. by having a similar pattern on abdomen and carapace ( Figs 3C , 4C ), but males can be distinguished by the morphology of the embolus tip ( Fig. 3D ) where the embolus have two long spine-like projections (instead only one in C. juragua and C. serrucho sp. nov. ) and several small spinules at the tip ( Fig. 8B ); females with a lower posterior receptacle, formed on the anterior margins by two thick membranous bars and a well-sclerotized central one ( Fig. 4E ). Description . Male ( holotype ): Carapace orangish brown with a dark and poorly developed pattern as in Fig. 3C . Chelicerae, palps, endites, labium, sternum and legs light orangish brown; femora and tibiae of legs and palps without 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 2.25. Carapace 0.70 long, 0.55 wide. Tegulum oval with embolus longer than tegulum width; embolus tip shape as figures 3D, 8B; with two long spine-like projections and several small spinules at the tip. Female (MPEG 37302): orangish brown with a dark and poorly developed pattern as in Fig. 4C . Chelicerae, palps, endites, labium, sternum, coxae, legs, abdomen, anal tubercle and spinnerets as in male. Total length 3.05. Carapace 1.00 long, 0.65 wide. External genital area with weakly sclerotized area ( Fig. 4D ). Internal genitalia with a low triangular posterior receptacle, where sperm are stored during mating, formed on the anterior margins by two thick membranous bars and a well-sclerotized central one ( Fig. 4E ), and a short membranous uterus externus (presumed anterior receptacle), where fertilization occurs.
