Differential diagnosis
Females of A. salgueiroi sp. nov. can be differentiated from those of A. porta sp. nov. and A. ibarrai sp. nov. by their larger size, reddish color in alcohol (Fig. 42A–D), epigynal lateral borders almost touching, atrium greatly reduced, and genital openings inside two large semicircular sclerotized plates (Fig. 42E–F).
Etymology
The species epithet is dedicated to Dr Francisco Javier Salgueiro-Sepúlveda, former member of the second author’s lab.

Description
Female
Total length 8.2. Carapace orange over cephalic area with two red longitudinal bands over most of thoracic area, lateral margins yellow, clypeus red. Sternum pale orange, darker at margins, intercoxal triangles present on all legs. Labium red, white at tip, longer than wide. Endites pale orange, rectangular, slightly broader at tip. Chelicerae orange, promargin with five teeth, retromargin with six to seven denticles. Leg coloration: yellow at base, turning red after femora to tarsi (Fig. 42A–D). Lateral sides of abdomen dorsum covered with red reticulated pattern leaving clearer central longitudinal band, lateral sides with same pattern, less dense ventrally. Tracheal spiracle at center, anterior half of abdomen surface almost without red pattern, posterior half dominated by reddish longitudinal lines (Fig. 42A–C). Epigynum atrium rectangular, longer than wide, door-shaped. Hood narrow and straight. Copulatory openings inside two semicircular sclerotized plates (Fig. 42E–F). Copulatory ducts weakly sclerotized following external edge of semicircular plates, turning 180° beyond hood, and entering spermathecae ventrally at junction between long seminal receptacles and fertilization duct origin. Fertilization ducts short and curved (Figs 42E–F, 44 A-B). Cephalothorax length 2.98, thoracic width 2.24, cephalic width 1.35. Clypeus height 0.11. Eye diameters: AME 0.1, ALE 0.13, PME 0.13, PLE 0.12. Eye interdistances: AME–AME 0.06, AME–ALE 0.04, ALE–PLE 0.18, PME–PME 0.17, PME–PLE 0.11. Femur lengths: I 2.52, II 2.42, III 1.97, IV 2.58. Leg spination: femur I d1-1-1, p0-1-1, r0-1-1. Tibia I v2-2-0, p1-1-1, r1- 1-1. Metatarsus I v2-2-0, p1-1-1, r1-1-1. Femur II d1-1-1, p0-1-1, r0-1-1. Tibia II v2-2-0, p1-1-1, r1-1-1. Metatarsus II v2-2-0, p1-1-1, r1-1-1. Femur III d1-1-1, p0-1-1, r0-1-1. Tibia III v2-2-2, p1-1-1, r1-1-1. Metatarsus III v2-2-2, p1-1-2, r1-1-2. Femur IV d1-1-1, p0-0-1, r0-0-1.
