Etymology. The specific name is a patronym in honor of Abel Pérez, collector of the paratypes and other material examined.

Diagnosis. Males of Antilloides abeli n. sp. differ from other species by the palpal tibia being two times longer than the cymbium and the tibial spines longer than cymbium ( Figs 9C‒D , 11A , 20A‒B ). The females are distinguished from other species by the S-shaped necks and elongated uterus externus with subtriangular distal area in the female genitalia ( Figs 9F , 20C ).

Description. Male (Holotype, Viñales National Park, Pinar del Río, Cuba). Carapace pale, clypeus with two lateral dark patches and a black spot posterior to the ocular area. Chelicerae orange. Labium and endites orange at tips and yellowish at bases. Palps and legs yellowish with ventral longitudinal black lines ventrally on the femora. Abdomen dorsally cream with 7–8 black chevrons ( Fig. 9A‒B ). Total length 3.1. Carapace length 1.7, width 1.4. PME separated by their diameter. Palp measurements: femur 1.1 long, patella 0.4 long, tibia 0.7 long, 0.4 wide. Leg measurements: I femur 3.7/ patella 0.7/ tibia 4.3/ metatarsus 3.9/ tarsus 2.0/ total 14.6; II 2.7/ 0.7/ 2.9/ 2.0/ 1.1/ 9.4; III 2.1/ 0.6/ 1.9/ 1.8/ 0.9/ 7.3; IV 2.8/ 0.7/ 2.6/ 2.4/ 1.1/ 9.6. Palp: tibiae with two or three spines ( Figs 9C , 11A ); embolus longer than tibial spines and sinuous at tip ( Fig. 11A, D ). Abdomen 1.9 long.

Female. (Paratype, Viñales National Park, Pinar del Río, Cuba). Coloration as in male (9B). Total length 5.0. Carapace length 2.2, width 1.5. PME separated by their diameter. Palp measurements: femur 1.4 long, patella 0.7 long. Leg measurements: I femur 3.1/ patella 0.8/ tibia 3.4/ metatarsus 2.8/ tarsus 1.5/ total 11.6; II 2.3/ /0.7/ 2.1/ 1.8/ 1.0/ 7.9; III 1.9/ 0.7/ 1.4/ 1.6/ 0.8/ 6.4; IV 2.6/ 0.7/ 1.9/ 2.1/ 1.0/ 8.3. Abdomen 2.6 long. Spermathecae with sinuous necks and globose receptaculum on the border of the cuticular fold ( Figs 9F , 20C ).

Natural history. The specimens were collected by hand, mainly at night, inside caves, in walls of the twilight area.

Distribution. Known only from Pinar del Río, Cuba ( Fig. 22 B).
