Figs 3A–B

Type material. Holotype: male from Hellshire Hills, Saint Catherine Parish, Jamaica, 300–500m, dry forest in limestone karst, 17o 52’N, 76o 58’W, II–III.1997, B. Wilson col., CAS.

Additional material examined. None.

Etymology. The species epithet is a toponym in apposition.

Diagnosis. Males of Ctenus catherine (Figs 3A–B) resemble those of C. serratipes (Polotow & Brescovit 2012: figs 4A–B) by the absence of tegular apophysis and prominent laminar basal projection of embolus, but can be distinguished by the large median apophysis and retrolateral tibial apophysis with large base and truncated laminar apex.

Chelicerae with 3 promarginal teeth, median largest; 4 retromarginal subequal teeth and one basal small teeth; without intermarginal denticles. Leg measurements: I: femur 11.80/ patella 4.90/ tibia 12.70/ metatarsus 11.90/ tarsus 4.00/ total 45.30; II: 11.80/ 4.90/ 11.80/ 11.10/ 3.60/ 43.20; III: 10.20/ 4.10/ 9.70/ 10.10/ 3.30/ 37.40; IV: 12.50/ 4.20/ 12.30/ 16.60/ 4.40/ 50.00.
