Diagnosis. Males resembles other species with coiled embolus ( A. simoni , A. kethleyi and A. ashmolei ) but can be distinguished from A. simoni by the longer bristles extending further beyond the tip of cymbium, the inner one shorter ( Figs 44, 45 ), both bristles shorter in the latter species (see Platnick & Shadab 1979, fig. 16); from A. kethleyi and A. ashmolei by cymbium with two subterminal bristles ( Figs 44, 45 ), terminal bristles in the latter two species ( Platnick & Shadab 1979, figs. 17, 19). Females may be recognized from all species by the spermathecae situated above the pedicel (see Platnick & Shadab 1979, figs 34, 35).

Description: Male: Total length: 1.23; carapace length: 0.59; carapace width: 0.49; abdomen length: 0.64; abdomen width: 0.55; clypeus height: 0.28. Cephalothorax: Carapace orange; pars cephalica reticulated with one large sulci laterally; cephalic groove inconspicuous, smooth; pars thoracica reticulated ( Fig. 60 ). Sternum orange, reticulated suffused with gray, longer than wide and covered with setae. Clypeus orange, reticulated. Labral spur present. Chelicerae orange, promargin with three teeth, retromargin without teeth or denticles. Eyes: 6 eyes, rounded; AME absent, ALE separated by their 3x their diameter, ALE-PLE contiguous, LE-PME separated by slightly more than their diameter, PME contiguous. Abdomen: Rounded, with dorsal orange scutum; soft portion whitish dorsally, laterally suffused with gray apically ( Fig. 60 ); spinneret scutum absent. Legs: Orange; femur I with ventral tubercles, tibiae I with one prolateral cusp, metatarsus I with two prolateral cusps and one retrolateral; metatarsus and tarsus II without cusp. Genitalia: Palpal femur with strong distal recurved apophysis; patellae with small, recurved retrolateral apophysis; palpal tibia elongated, pointed apically ( Figs 44, 45 ). Cymbium with two curved, subterminal stiff bristles ( Fig. 45 ). Embolus long, with four coils ( Fig. 44 )

Female: See Platnick & Shadab 1979 (p.11, figs 34, 35).

Natural History. This species was collected by pitfall trap between 900–2,225m.

Distribution. Ecuador: Pichincha, Santo Domingo de los Tsáchilas and Cotopaxi provinces.
