Tliltocatl Mendoza & Francke, 2020 Description. Carapace regularly as long as wide, caput slightly elevated. Cephalic striae inconspicuous. Fovea deep, straight or recurve. Eye tubercle distinct and raised, wider than long. Anterior eye row procurved, posterior eye row recurved. Clypeus narrow or absent. Labium subtrapezoidal, wider than long, with 85–120 cuspules on anterior third centre. Maxilla subrectangular, anterior lobe distinctly produced into conical process, inner corner with 130–220 cuspules. Sternum longer than wide. Anterior pair of sigillae circular and slightly seen, second pair oval enlarged, posterior pair oval or rounded, generally once its length from the sternum margin. Leg formula: I, II, III, IV. Tarsi I–IV fully scopulated. All tarsi scopulae are undivided. Metatarsi I–II fully scopulated. Metatarsus III is 50% distally scopulated and metatarsus IV is 20–40% distally scopulated. The femur of leg III is slightly enlarged but not swollen as in other genera. Femora IV without retrolateral scopulae. Claviform stridulating setae on palp trochanter retrolateral face and in leg I trochanter and femur prolateral face. Patellae of the legs have at least one spine on prolateral or retrolateral side. Posterior lateral spinneret distally elongating, digitiform. Both sexes possess urticating setae type I and type III; Type III are located in the dorsoposterior area and type I surrounding these. Males possess two tibial apophysis, retrolateral apophysis slightly curved in apically. Globous bulb with small subtegulum longer than its height. Embolus flattened, longer than tegulum, with prolateral superior and apical keel large, joint at the embolus tip forming a typical spoon-shape. Prolateral inferior keel well developed, parallel to prolateral superior and larger in general. Females with a simple undivided/fused spermatheca apically narrowed and medially curved inwardly. Spermathecal baseplate absent or slightly developed. Spermatheca midwidth shorter than its base and well sclerotized. Most of the species are black with long, red setae on the opisthosoma (except T. albopilosum, T. schroederi and T. verdezi). Juveniles are similar in colour to the adults but paler. |
