Material examined. Male holotype and two female paratypes from Ecuador, Cotopaxi Province, OTONGA Biological Reserve (-00.41994 -79.00623) 1,997m, 13–15.xi.2014, sifting mosses, N. Dupérré, E. Tapia, C. Tapia ( QCAZ) . Paratypes: Ecuador, Cotopaxi Province, OTONGA Biological Reserve (-00.41994 -79.00623) 1,997m, 4–7.ix.2014, 2♂ 1♀, 13–25.xi.2014, 2♂, sifting mosses, N. Dupérré, E. Tapia, C. Tapia ( ZMH) .

Etymology. The specific name is a noun in apposition taken from the Kichwa language meaning “similar”.

Diagnosis. Males closely resemble A. mariebertheae n. sp. but can be distinguished from the latter by their higher clypeus, deeper cephalic groove ( Fig. 56 ); from all other species the male is distinguished by a dark elongated conductor and cymbial apical extension ( Fig. 38 ), females most resembles A. monteverde Platnick & Shadab 1978 but can be distinguished by their non-pointed abodomen ( Fig. 57 ), pointed in the latter ( Platnick & Shadab 1978); from all other species by their short copulatory ducts and long, sinuous fertilization ducts ( Figs 42, 43 ); long copulatory ducts and short fertilization ducts in A. anabelleae n. sp. ( Fig 6 ).

Description. Male (holotype): Total length: 1.14; carapace length: 0.42; carapace width: 0.42; abdomen length: 0.72; abdomen width: 0.75; clypeus height: 0.1.Cephalothorax: Carapace orange; pars cephalica puntated, Y-shaped punctation reaching LE; cephalic groove deep, punctated; pars thoracica dorsally rugose, laterally punctated ( Fig. 56 ). Sternum orange, suffused with dark gray, punctated, longer than wide, covered with setae. Labral spur present. Clypeus orange, punctated. Chelicerae orange, excavated medially with characteristic denticulate plate apically. Eyes: 6 eyes, rounded; AME absent, ALE separated by their diameter, ALE-PLE contiguous, LE-PME separated by their radius, PME contiguous. Abdomen: rounded, with dorsal orange scutum; soft portion whitish covered with small setose sclerites, laterally with rows of small setose sclerites slightly suffused with dark gray apically ( Fig. 56 ), complete spinneret scutum. Legs: Orange; metatarsus I and tarsus I without cusps ( Fig. 40 ); metatarsus II slightly enlarged with one ventral; tarsus II with four cusps ( Fig. 41 ). Genitalia: Palpal patella with small, ventrally curved retrolateral apophysis; palpal tibia with one retrolateral trichobothrium; large scoop-shaped retrolateral apophysis ( Fig. 39 ). Cymbium cup-shaped, with extension ( Figs 38, 39 ). Embolus not reaching tip of conductor; conductor dark, strongly ridged, long, rounded apically ( Figs 39, 39a ).

Female (paratype): Total length: 1.22; carapace length: 0.45; carapace width: 0.41; abdomen length: 0.77; abdomen width: 0.63. Cephalothorax: Same coloration and pattern of punctation as male ( Fig. 57 ). Chelicerae and sternum as male. Labral spur present. Eyes: 6 eyes, AME absent, ALE separated by their diameter, ALE-PLE contiguous, LE-PME separated by half their diameter, PME contiguous. Abdomen: Light gray, rounded without dorsal scutum; dorsal soft portion with small, rounded setose sclerites; eight large non setose sclerites; dorsolaterally with six-seven large non setose sclerites; laterally with numerous small, rounded setose sclerites, slightly suffused with gray apically ( Fig. 57 ); spinneret scutum complete. Legs: Orange; without cusps. Genitalia: Ventral scutum bright orange, visible through the scutum: a pair of large rounded spermathecae, straight copulatory ducts ( Fig. 42 ). Internal genitalia with large rounded spermathecae; copulatory ducts short; fertilization ducts sinuous, directed medially ( Fig. 43 ).

Distribution. Ecuador: Known only from the type locality.

Natural History. All specimens were taken at an elevation of 1,997m in mosses.
