Genus Filistatoides View in CoL View at ENA F. O. P.-Cambridge, 1889

Filistatoides View in CoL F. O. P.- Cambridge, 1899: 47 (Type species by original designation Filistatoides insignis View in CoL 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 View FIGURE 1 A ‒ D , 8A‒B View FIGURE 8 A ‒ J. A ‒ D ) and short, distal, dentate ( Figs 2E‒F View FIGURE 2 A ‒ H ; 6E-F) or acute and smooth ( Fig. 8I View FIGURE 8 A ‒ J. A ‒ D ) paraembolic lamina. Females can be distinguished by the large base of the spermathecae constricted anteriorly, forming a rounded distal receptacle ( Figs 3E View FIGURE 3 A ‒ E , 8G View FIGURE 8 A ‒ J. A ‒ D ).

Description. Small, 2.5–4.5. Carapace ovoid, with shallow thoracic fovea in males ( Fig. 4D View FIGURE 4 A ‒ H ), absent in females; posterior border of carapace notched ( Fig. 4C View FIGURE 4 A ‒ H ). Eight eyes grouped on a distinct tubercle, AME smaller than others ( Fig. 4B View FIGURE 4 A ‒ H ). Clypeus projecting anteriorly ( Fig. 4B View FIGURE 4 A ‒ H ). Chelicerae fused at base, with distal promarginal lamina ( Figs 4G‒H View FIGURE 4 A ‒ H ). Endite serrula with 14–16 short teeth ( Fig. 4F View FIGURE 4 A ‒ H ). Sternum without sigilla, fused at labium ( Fig. 4E View FIGURE 4 A ‒ H ). Spines absent in legs and pedipalps. Female palpal tarsus setose, claw with 11–12 teeth and elongated sensilla ( Fig. 5F View FIGURE 5 A ‒ H ). Legs with dorsal sensilla and scattered chemosensitive setae ( Fig. 6A View FIGURE 6 A ‒ H ). 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 View FIGURE 5 A ‒ H ). Tarsal organ rounded, slightly elevated and smooth ( Fig. 2H View FIGURE 2 A ‒ H ). Abdomen oval and hirsute ( Fig. 1A View FIGURE 1 A ‒ D ). Cribellum divided with fusiform spigots in the spinning field ( Fig. 5A‒B View FIGURE 5 A ‒ H ). Spinnerets subterminal. ALS with one major ampullate gland spigot and several piriform gland spigots ( Fig. 5C‒D View FIGURE 5 A ‒ H ). 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 View FIGURE 5 A ‒ H ). Male palpal femur long, two times the length of the palpal tibia ( Fig. 1C‒D View FIGURE 1 A ‒ D ), with a ventral basal group of erect setae ( Fig. 2G View FIGURE 2 A ‒ H ). Palpal tibia narrow and long, with a distal group of long setae s and a ventrodistal arthrodial membrane ( Figs 2B, D View FIGURE 2 A ‒ H , 6C‒D View FIGURE 6 A ‒ H ). 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 View FIGURE 2 A ‒ H ). Tegulum globose ( Fig. 2A View FIGURE 2 A ‒ H ). Embolus long, with short paraembolic lamina ( Fig. 2A‒B, E‒F View FIGURE 2 A ‒ H ). Female genitalia with paired receptacle with large receptacle base, short neck and interpulmonary membrane reaching the neck of the spermathecae ( Figs 3E View FIGURE 3 A ‒ E , 8G View FIGURE 8 A ‒ J. A ‒ D ).
