Diagnosis
The males of A. yiselae sp. nov. resemble those of A. noono and A. hoof sp. nov. by having a short embolus, shorter than the palpal tibia, but can be distinguished by a slender and sinuous embolus tip, without denticles and with a longer and thin hyaline process (Figs 3H, 5A). Females can be distinguished from those of the other species with a T-shaped sclerotized bifid duct on the anteromedian receptacle base by having it with a convex anterior margin (Fig. 6D) (vs concave anterior margin in other species).
Etymology
The specific name is a patronym honoring Yisel Krauss, the sister of the first author.

Description
Male (holotype)
Carapace orange (Fig. 3C). Chelicerae, palps, endites, labium, sternum and legs light orange; coxae and trochanters lighter. Abdomen pale gray, with dorsal dark gray chevron pattern as in Fig. 3A; ventral part pale gray without stains (Fig. 3B). Anal tubercle and spinnerets lighter than abdomen. Crista short, covering little more than half of metatarsus I, covering less than half of metatarsus II. Total length 3.9. Carapace 1.8 long, 1.3 wide. Sternum 1.6 long, 1.2 wide. Leg measurements: I: 5.3; II: 5.0; III: 4.7; IV: 5.5. Tegulum globose, spherical; embolus short, length not reaching palpal tibia length, with wide base and narrow tip that looks like triangle in lateral view, with slender and sinuous embolus tip, without denticles and with long and thin hyaline process (Figs 3H, 5A).
Female (paratype)
Carapace, chelicerae, palps, endites, labium, sternum, coxae, legs, abdomen, anal tubercle and spinnerets as in male (Fig. 4A–D). Crista covering all ventral part of metatarsi. Total length 4.2. Carapace 2.0 long, 1.5 wide. Sternum 1.9 long, 1.5 wide. Leg measurements: I: 5.4; II: 5.2; III: 4.9; IV: 5.6. External genital area with strongly sclerotized ess (Fig. 6A). Internal genitalia with T-shaped sclerotized bifid duct on anteromedian receptacle base and convex anterior margin (Fig. 6D); sac-like membranous structure long and wide (Figs 6B, 11E–F); membranous posterior receptacle covering pair of horizontal sclerotized bars communicating with sclerotized bifid duct on anteromedian receptacle base (Figs 6D, 11E–F).
Distribution
Known only from the type locality in Mexico (Fig. 13).
