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.

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.
