Etymology. In honor of Carmen Caisaguano for her work in collecting spiders and preserving Ecuador remaining low evergeen forest.

Diagnosis. Males can be distinguished from A. anchicaya by the presence of only two ventral cusps on tarsus II ( Fig. 11 ), three in the latter species; from A. saladito by their non-swollen tarsus I ( Fig. 10 ), swollen in the latter. Females can be distinguished from A. anchicaya and A. atuncela by the absence of a abdominal scutum ( Fig. 49 ); from A. saladito by the presence of two to three ventral cusps on tarsi I–II, five cusps in the latter species; from A. meta by the ALE separated by their diameter and a rounded abdomen not pointed posteriorly ( Fig. 49 ).

Description. Male (holotype): Total length: 1.6; carapace length: 0.72; carapace width: 0.58; abdomen length: 0.88; abdomen width: 0.79; clypeus height: 0.18. Cephalothorax: Carapace reddish; pars cephalica punctated dorsally; cephalic groove deep, punctated; pars thoracica punctated laterally, slightly granulate dorsally ( Fig. 48 ). Sternum orange, suffused with dark gray, deeply punctated, longer than wide, covered with setae. Labral spur present. Clypeus reddish, 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 diameter, PME contiguous. Abdomen: Rounded with orange dorsal scutum, dorsal soft portion with small, rounded setose sclerites; laterally suffused with three stripes of dark gray ( Fig. 7 ), alternating with rows of elongated non-setose sclerites or stripes completely absent ( Fig. 48 ); spinneret scutum complete. Legs: Orange; metatarsus I with one cusp; tarsus I with two to three cusps ( Fig. 10 ); metatarsus II swollen with one prolateral and one ventral cusps; tarsus II with two cusps ( Fig. 11 ). Genitalia: Palpal patella with triangular, ventrally curved retrolateral apophysis; palpal tibia with one retrolateral trichobothrium and a scoop- shaped retrolateral apophysis ( Fig. 8 ). Cymbium cup-shaped with small cap-like extension ( Fig. 9 ). Embolus almost reaching tip of conductor; conductor transparent, strongly ridged, small, pointed ( Figs 8, 8a ).

Female (paratype): Total length: 1.82; carapace length: 0.73; carapace width: 0.62; abdomen length: 1.09; abdomen width: 0.95; clypeus height: 0.18. Cephalothorax: Same coloration and pattern of punctation as male ( Fig. 49 ). Clypeus orange, punctated. 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 half their diameter, PME contiguous. Abdomen: Light to dark gray, rounded without dorsal scutum; dorsal soft portion with small, rounded setose sclerites; eight large non setose sclerites; dorso-laterally with six large non setose sclerites; laterally with three stripes of dark gray, alternating with rows of elongated non-setose sclerites or stripes completely absent; spinneret scutum complete ( Fig. 49 ). Legs: Orange; metatarsus I with one cusp, tarsus I with three cusps; metatarsus II with one cusp and tarsus II with two to three cusps. Genitalia: Ventral scutum bright orange, visible through the scutum: pair of large oval spermathecae; short copulatory ducts ( Fig. 12 ). Internal genitalia with large oval spermathecae; copulatory ducst short, semi-transparent ( Fig. 12 ); fertilization ducts short, directed apically ( Fig. 13 ).

Natural History. Specimens were collected by pitfall trap between 900–2,225m.

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

Remark. This is the only species where males and females have the same clypeus height.
