Type species. Antilloides abeli new species

Etymology. The generic name is a contraction of Antilles plus “oides”, and is neuter in gender.

Diagnosis. Males of Antilloides can be distinguished from other American Prithinae by the tibia with two-three strong, distally rhomboid spines on a projected area ( Figs 9C View FIGURE 9 A ‒ F , 11A, D‒E View FIGURE 11 A ‒ H ) and the cymbium is elongate distally and is approximately the length of the embolus ( Fig. 16C‒F View FIGURE 16 A ‒ H ). Females can be distinguished from other Prithinae by the genitalia having an anterior, elongated uterus externus ( Fig. 9F View FIGURE 9 A ‒ F ) and one pair of spermathecae with narrow and sinuous necks on the border of the cuticular fold ( Figs 17 View FIGURE 17 A ‒ E F, 20C).

Description. Size small, 1.8–5.0. Carapace ovoid, with inconspicuous thoracic fovea in males, absent in females ( Fig. 9A‒B View FIGURE 9 A ‒ F ), posterior border truncate ( Figs 13A View FIGURE 13 A ‒ C , 14B View FIGURE 14 A ‒ E ). Eight subequal eyes grouped on a distinct tubercle. Clypeus almost horizontal ( Fig. 9A View FIGURE 9 A ‒ F ). Chelicerae robust, fused at base, with distal promarginal lamina, and serrula with short teeth ( Fig. 15A‒D View FIGURE 15 A ‒ H ). Sternum without sigilla, fused at labium. Spines absent on legs. Female pedipalpal tarsus hirsute, no spines, claw with 10–11 teeth. Leg I–IV with many irregularly distributed sensilla and featherlike setae ( Fig. 15D‒G View FIGURE 15 A ‒ H ) as well as chemosensitive setae ( Figs 10C View FIGURE 10 A ‒ H , 15D View FIGURE 15 A ‒ H ). Leg II of male unmodified. Calamistrum short, triseriate, comprising elongate and comb-like setae ( Figs 10E‒F View FIGURE 10 A ‒ H , 15H View FIGURE 15 A ‒ H ). Three pectinate claws, the paired claws with 7–9 teeth and the unpaired claw with 3–4 teeth ( Fig. 10A‒D View FIGURE 10 A ‒ H ). Tarsal organ capsulated, slightly elevated and smooth ( Fig. 15E‒F View FIGURE 15 A ‒ H ) sometimes paired with a sensill ( Fig. 15G View FIGURE 15 A ‒ H ). Male palpal femur long, almost one third larger than tibia ( Fig. 9C‒D View FIGURE 9 A ‒ F ), with a ventral median group of erect setae. Tibia thick, longer than the patella, hirsute, no spines, lyriform organs subdistal ( Fig. 19G‒H View FIGURE 19 A ‒ H ) and with a retrolateral distal projection with strong spines that have a blunt distal area ( Figs 9C View FIGURE 9 A ‒ F , 11A, D‒E View FIGURE 11 A ‒ H , 16B, G View FIGURE 16 A ‒ H ). Cymbium long, narrow, very slender, distally tapering, reaching almost to the embolus tip ( Fig. 16A‒F View FIGURE 16 A ‒ H ), with at least one small sensill, scattered chemosensitive setae ( Fig. 11G View FIGURE 11 A ‒ H ), one smooth seta on the prolateral border ( Fig. 11H View FIGURE 11 A ‒ H ) and feathery setae that are elongated at the tip ( Fig. 16C‒D View FIGURE 16 A ‒ H ). Tegulum pyriform ( Fig. 9D View FIGURE 9 A ‒ F ). Embolus long, without paraembolic lamina, generally sinuous at tip ( Figs 11A View FIGURE 11 A ‒ H , 16C‒G View FIGURE 16 A ‒ H ). Female genitalia with an elongated uterus externus, sometimes surpassing dorsally the spermathecae ( Fig. 14E View FIGURE 14 A ‒ E ) or short, but enlarged in some species ( Figs 20D View FIGURE 20 A ‒ G. A ‒ C ; 21C) and one pair of spermathecae with a narrow and sinuous neck leading to a globose or oval receptaculum ( Figs 9F View FIGURE 9 A ‒ F , 14E View FIGURE 14 A ‒ E , 20C View FIGURE 20 A ‒ G. A ‒ C ). Abdomen oval and slightly hirsute ( Fig. 9A‒B View FIGURE 9 A ‒ F ). Cribellum divided ( Figs 10H View FIGURE 10 A ‒ H , 12A View FIGURE 12 A ‒ F. A ‒ D ). Spinnerets subterminal. ALS and PMS with rows of large modified setae ( Fig. 12B View FIGURE 12 A ‒ F. A ‒ D ). ALS with one major ampullate gland spigot situated laterally to the piriform gland spigot field ( Fig. 12C View FIGURE 12 A ‒ F. A ‒ D ). PLS with clavate setae, at least two aciniform spigots ( Fig. 12D View FIGURE 12 A ‒ F. A ‒ D ) and at least one paracribellar gland spigot ( Fig. 12A View FIGURE 12 A ‒ F. A ‒ D ). PMS with one paracribellar gland spigot, one minor ampullate gland spigot and a few aciniform gland spigots ( Fig. 12E‒F View FIGURE 12 A ‒ F. A ‒ D ).
