Etymology. The species epithet, a noun in apposition is taken from the “Popoluca de la Sierra” word for cat.
Diagnosis. Males of A. misi sp. n. differ from other species of the genus by having a thin, sharpened embolus tip (Fig. 55). Females of A. misi sp. n. share with A. chimpa sp. n. a large membranous sac (Figs. 35, 54) but differ from this species by having a short, wide T-shaped sclerotized bifid duct, by the anterior margin of the transverse rigid plate dorsally curved along its total length and by the presence of small projections on the postero-median invagination (Figs. 49, 54).
Description. Male (Holotype). Total length 4.1. Cephalothorax 1.75 long, 1.35 wide. Sternum 1.15 long, 0.85 wide. Legs: I 4.76 (1.42) (0.80) (1.20) (0.84) (0.50); II 4.40 (1.30) (0.70) (1.10) (0.80) (0.50); III 3.74 (1.06) (0.50) (0.84) (0.84) (0.50); IV 5.86 (1.60) (0.72) (1.40) (1.48) (0.66). Carapace surface orange; weak patterned (Fig. 38). Sternum, chelicerae, labium, palps, and legs orange; coxae and trochanters lighter (Figs. 39, 41, 42). Endites pale orange, anterior margin lighter. Abdomen dark gray, with a dorsal pattern of four white chevrons, ventral surface lighter (Figs. 38, 40). Anal tubercle and spinnerets light orange. Crista long, covering about 3/4 of metatarsus length in leg I, occupying about a half of metatarsus length in leg II (Figs. 50, 51). Paired claws with five teeth (Figs. 53). PLS longer than PMS. Prolateral brush of palpal tibia with nine setae (Fig. 56); bulb globose, spherical; spermatic duct with a long, hyaline process resting over the embolus tip (Fig. 55); embolus about the same length of palpal tibia (Fig. 44), distal portion bent (Figs. 44, 46), with a thin, sharpened tip (Fig. 55).
Female (Paratype). Total length 6.20. Cephalothorax 2.40 long, 1.84 wide. Sternum 1.52 long, 1.16 wide. Legs: I 6.99 (2.17) (1.25) (1.75) (1.20) (0.62); II 6.61 (1.95) (1.15) (1.67) (1.22) (0.62); III 5.47 (1.62) (0.80) (1.25) (1.25) (0.55); IV 7.99 (2.25) (1.05) (1.87) (2.07) (0.75). Carapace surface dark orange; weak patterned. Sternum, chelicerae, and labium dark orange. Palps and legs orange; coxae and trochanters lighter. Endites pale orange, anterior margin lighter. Abdomen as in male. Crista long, covering all metatarsus length (Fig. 52), wider on leg I. Paired claws with five teeth (Figs. 53). PLS same size as PMS. Internal genitalia with the anterior margin of plate dorsally curved along its total length (Fig. 49), posterior median invagination wide, with small projections (Fig. 49); membranous anteromedian receptaculum formed by a short, wide T-shaped sclerotized bifid duct that protrudes from the posterior surface of plate leading to a large, membranous oval sac (Figs. 48, 49, 54).
Variation. N = 1 ♂. Total length 4.95. Cephalothorax 1.90 long, 1.45 wide. Sternum 1.25 long, 0.95 wide.
