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.
