Etymology. The specific name is a noun in apposition taken from the type locality.

Diagnosis. Antilloides haitises n. sp. is distinguished from other species by tibial spines shorter than the cymbium and an embolus that is slender at the tip ( Figs 14C‒D 16A‒H , 20E‒F ). The females differ by the elongated and very large uterus externus and the enlarged necks of the spermathecae ( Figs 14E , 20G ).

Description. Male (Holotype). Carapace and legs yellowish. Chelicerae orange. Labium and endites orange at tips and yellow at bases. Sternum yellow. Palps and legs grayish with sparse black stripes. Abdomen dorsally grayishwith 6–7 black chevrons, ventrally white ( Fig. 14A ). Total length 2.1. Carapace length 1.1, width 0.75. PME separated by their diameter. Palp measurements: femur 0.7 long, patella 0.25 long, tibia 0.35 long, 0.2 wide.

PME separated by their diameter. Palp measurements: femur 0.9 long, patella 0.4 long. Leg measurements: I femur 1.7/ patella 0.6/ tibia 1.9/ metatarsus 1.2/ tarsus 1.0/ total 6.4; II 1.3/ 0.6/ 1.0/ 0.7/ 0.6/ 4.2; III 1.0/ 0.5/ 0.7/ 0.6/ 0.6/ 3.0; IV 1.5/ 0.6/ 1.3/ 1.1/ 0.7/ 5.2.
