Diagnosis
. Males resemble similar congeners
Nops pallidus
n. sp.
and
Nops gertschi
by having a short and thick embolus, strongly curved; but can be distinguished by the longer embolus with a shorter sclerotized margin (
Fig. 31B‒C
). Females can be distinguished by receptaculum with narrow invagination and uterus externus with narrow base (
Fig. 30G‒H, J‒L
).
Description
.
Male
(
holotype
): Carapace, chelicerae, labium, endites, sternum and legs yellow (
Fig. 31A
), coxae and trochanters lighter. Abdomen pale gray, without noticeable dorsal pattern on abdomen, lighter ventrally. Anal tubercle and spinnerets light gray. Total length 9.3. Carapace 6.4 long, 4.3 wide. Sternum 3.9 long, 3.6 wide. Leg measurements: I: 4.4; II: 4.15; III: 3.8; IV: 4.5. Posterior unpaired claws short, as in other three‒clawed spiders. PLS longer than PMS. Femur I‒II slight elongated. Palp with embolus distinctly shorter than tibia, thick and strongly curved (
Fig. 31B‒C
); beveled tip with a wide sclerotized margin and two short extensions (
Fig. 30B‒C
).

Female
(BSC 550): Carapace, chelicerae, labium, legs, coxae, endites and sternum as in male (
Fig. 31D
). Abdomen as in male. Anal tubercle and spinnerets as in male. Total length 9.7. Carapace 6.8 long, 4.5wide. Sternum 4.3 long, 3.9 wide. Leg measurements: I: 4.6; II: 4.35; III: 3.70; IV: 4.8. Posterior unpaired claws and PLS as in male. External genital area with weakly sclerotized anterior plate and lep, unremarkable ess (
Fig. 31E
). Internal genitalia with narrow invagination on receptaculum and uterus externus with narrow base (
Figs 30G‒H, J‒L
; 31F).
Variation
. Specimens from eastern
Cuba
populations differ slightly in coloration from those of the western region. Specimens from
Santiago
de
Cuba
(eastern) have accentuated overall coloration, being slightly darker and have slight differences in embolus shape compared with males from west of
Cuba
.
Natural history
. All specimens from
Santiago
de
Cuba
were collected under stones in xerophytic coastal scrub. Specimens from
Guantánamo
were collected under dead plants of
Agave
sp. in secondary scrub.
Distribution
. Known from a few localities in
Cuba
(
Fig. 31G
).
