description: Genus Filistatoides F. O. P.-Cambridge, 1889
Filistatoides F. O. P.- Cambridge, 1899: 47 (Type species by original designation Filistatoides insignis O. P.- Cambridge, 1896).
Diagnosis. Males of Filistatoides can be distinguished from other American Prithinae by cylindrical palpal tibiae without a dorsal-retrolateral projection (Figs 1C‒D, 8A‒B) and short, distal, dentate (Figs 2E‒F; 6E-F) or acute and smooth (Fig. 8I) paraembolic lamina. Females can be distinguished by the large base of the spermathecae constricted anteriorly, forming a rounded distal receptacle (Figs 3E, 8G).
Description. Small, 2.5–4.5. Carapace ovoid, with shallow thoracic fovea in males (Fig. 4D), absent in females; posterior border of carapace notched (Fig. 4C). Eight eyes grouped on a distinct tubercle, AME smaller than others (Fig. 4B). Clypeus projecting anteriorly (Fig. 4B). Chelicerae fused at base, with distal promarginal lamina (Figs 4G‒H). Endite serrula with 14–16 short teeth (Fig. 4F). Sternum without sigilla, fused at labium (Fig. 4E). Spines absent in legs and pedipalps. Female palpal tarsus setose, claw with 11–12 teeth and elongated sensilla (Fig. 5F). Legs with dorsal sensilla and scattered chemosensitive setae (Fig. 6A). Calamistrum short, triseriate, composed of comblike setae. Three pectinate claws, the paired claws with 6–7 teeth and the unpaired claw with 5– 6 teeth (Fig. 5G‒H). Tarsal organ rounded, slightly elevated and smooth (Fig. 2H). Abdomen oval and hirsute (Fig. 1A). Cribellum divided with fusiform spigots in the spinning field (Fig. 5A‒B). Spinnerets subterminal. ALS with one major ampullate gland spigot and several piriform gland spigots (Fig. 5C‒D). PLS with one paracribellar gland spigot situated laterally to the aciniform gland spigot field (not illustrated). PMS with clavate setae covering the paracribellar gland spigots (Fig. 5E). Male palpal femur long, two times the length of the palpal tibia (Fig. 1C‒D), with a ventral basal group of erect setae (Fig. 2G). Palpal tibia narrow and long, with a distal group of long setae s and a ventrodistal arthrodial membrane (Figs 2B, D, 6C‒D). Cymbium short, half length of bulb, not fused to tegulum and with a row of needle-like setae along the dorsal border (Fig. 2A‒C). Tegulum globose (Fig. 2A). Embolus long, with short paraembolic lamina (Fig. 2A‒B, E‒F). Female genitalia with paired receptacle with large receptacle base, short neck and interpulmonary membrane reaching the neck of the spermathecae (Figs 3E, 8G).
Distribution. Mexico, Guatemala, Northern Colombia and Cuba.
