Type species: Cyrtopholis cursor ( Ausserer, 1875) View in CoL .

Diagnosis: Both sexes possess a stridulatory apparatus, composed of a set of claviform setae ( Figs 1–4 View FIGURES 1–4 ), located on the retrolateral face of palpal trochanters ( Figs 1–2 View FIGURES 1–4 ) and prolateral face of trochanters I ( Figs 3–4 View FIGURES 1–4 ) and urticating setae types I and III on abdominal dorsum. In males, the presence of the retrolateral process on the tibia of palp, metatarsus I bends over the retrolateral branch of the tibial apophysis. Females with spermathecae composed of two long receptacles and no fusion at the base (except in Cyrtopholis media Chamberlin, 1917 that the receptacles are fused at the base).

The genus Cyrtopholis resembles Acanthoscurria , Longilyra , Nesipelma and Phormictopus in the presence of stridulating claviform setae on the palpal trochanters. Males of Acanthoscurria are distinguished by the tibial apophysis composed of a single branch and females by the subspherical aspect of the spermathecal receptacles ( Pérez–Miles et al., 1996, figs 4–5). Longilyra is distinguished by the long claviform stridulatory setae ( Gabriel, 2014, figs 1–3) and females are distinguished by the spermathecae with fused receptacles ( Gabriel, 2014, figs 4–6). Males of Nesipelma have a straight palpal bulb embolus ( Gargiulo et al., 2018, fig. 4C) and females have short spermathecal receptacles, as long as wide ( Gargiulo et al., 2018, fig. 4D). Phormictopus is distinguished by the presence of claviform stridulating setae on trochanters and coxae of palps and legs I.

Distribution: Caribbean: Antilles.
