Etymology. The specific name is in honor of Anabelle Aurelia Tapia for her help collecting Ecuadorian spiders.
Diagnosis. Males are distinguished from most species by their swollen metatarsus I without cusp (Fig. 3) and the angular conductor of the palp (Figs 1, 2, 2a); from A. monteverde they are distinguished by the presence of three to four cusps on tarsus II (Fig. 4), one in the latter species (Platnick & Shadab 1978, fig. 26). Females can be distinguished from most species by straight copulatory ducts (Fig. 6), from A. monteverde by their unpointed abdomen (Fig. 47), pointed in the latter (Platnick & Shadab 1978); from A. shina n. sp. by their shorter fertilization ducts and longer copulatory ducts (Fig. 6) inverse in the latter species (Fig. 43).
Description. Male (holotype): Total length: 1.14; carapace length: 0.45; carapace width: 0.39; abdomen length: 0.69; abdomen width: 0.56; clypeus height: 0.11. Cephalothorax: Carapace orange; pars cephalica dorsally with Y- shaped punctation reaching lateral eyes; cephalic groove punctated; pars thoracica punctated laterally, slightly granulated dorsally (Fig. 46). Sternum orange, suffused with dark gray, deeply punctated, longer than wide, covered with setae. Labral spur present. Clypeus orange, punctated. Chelicerae orange, punctated, excavated medially; with one basal tooth and an apical denticulate plate. Eyes: 6 eyes, rounded; AME absent, ALE separated by their diameter, ALE-PLE contiguous, LE-PME separated by half their radius, PME contiguous. Abdomen: Rounded with orange dorsal scutum, dorsal soft portion with few small, rounded setose sclerites; laterally suffused with three stripes of dark gray, midway, alternating with rows of sclerites (Fig. 46); spinneret scutum complete. Legs: Orange; metatarsus I swollen without cusp; tarsus I without cusp (Fig. 3); metatarsus II slightly enlarged with one ventral cusp; tarsus II with three to four cusps (Fig. 4). Genitalia: Palpal patella with small, ventrally curved retrolateral apophysis; palpal tibia with one retrolateral trichobothrium, scoop-shaped retrolateral apophysis (Fig. 2). Cymbium cup-shaped with slight cap-like extension apically (Fig. 1). Embolus short not reaching the tip of conductor; conductor dark, ridged, short, angular, pointed apically (Figs 1, 2, 2a).
Female (paratype): Total length: 1.16; carapace length: 0.42; carapace width: 0.39; abdomen length: 0.76; abdomen width: 0.75; clypeus height: 0.09. Cephalothorax: Same coloration and pattern of punctation as male (Fig. 43). Chelicerae and sternum as male. Labral spur present. Eyes: 6 eyes, rounded, smaller than males; AME absent, ALE separated by their diameter, ALE-PLE contiguous, LE-PME separated by their diameter, PME contiguous. Abdomen: Light gray, rounded without scutum; dorsally with numerous small setose sclerites; laterally with few larger sclerites, darker apically (Fig. 47); spinneret scutum complete. Genitalia: Ventral scutum bright orange, visible through scutum: pair of large round spermathecae, straight copulatory ducts (Fig. 5); internal genitalia with round spermathecae; straight copulatory ducts; fertilization ducts short, directed medially (Fig. 6).
Natural History. Most specimens were collected between 1,717–2,105m.
Distribution. Ecuador: Known only from the type locality.
