Differential diagnosis

Females of A. jimenezi sp. nov. are differentiated from those of all species of the pectorosa and pacifica groups (Keyserling 1879; Pickard-Cambridge O. 1896; Pickard-Cambridge F. 1900; Kraus 1955; Platnick 1974; Dondale & Redner 1982; Sierwald 1988; Brescovit & Lise 1989; Brescovit 1997; Durán-Barrón et al. 2016) by the curved mustache-shaped lateral borders, and the genital openings being adjacent at the center of the epigynal plate (Figs 16E, 18C). Central and adjacent genital openings are also present in females of A. tonoi sp. nov. (Fig. 46E–F), but both species differ by the path and length of the copulatory ducts (Fig. 18B–C).

Etymology

The species epithet is dedicated to the Mexican arachnologist Dr María Luisa Jiménez.

Sternum surface white, intercoxal triangles present on all legs. Labium light brown, white at tip, longer than wide. Endites light yellow, rectangular, broader at tip (Fig. 16C). Chelicerae slightly darker than cephalothorax (Fig. 16B, D), promargin with five teeth, retromargin with eleven to twelve denticles. Leg coloration darker than cephalothorax and scattered brown patches irregularly distributed from femora to tarsi (Fig. 16A–C). Abdomen yellow-gray, dorsal and lateral surfaces with scattered darker patches, ventral surface without patterns, tracheal spiracle closer to epigastric furrow (Fig. 16A–C). Epigyum hood short, slightly curved, and over both genital openings. Anterior plate area delineated by two sclerotized curved notches at corners (Figs 16E–F, 18C– D). Seminal receptacles in anterior third of copulatory ducts. Copulatory duct path U-shaped, bending dorsally, and curving again to enter external lateral surface of spermathecae. Fertilization ducts short, cylindrical, entering spermathecae dorsally. Spermathecae longer than wide and between copulatory ducts coils (Fig. 18C–D).
