Figs 20–23 , 51 , 62a .

Material examined. Male holotype from Ecuador, Cotopaxi Province, OTONGA Biological Reserve (-00.41433 - 79.00035) 1888m, 3–16.viii.2014, pitfall trap, E. Tapia, C. Tapia, N. Dupérré ( QCAZ) . Male paratype OTONGA Biological Reserve Reserve (-00.41433 -79.00035) 1888m, 3–16.viii.2014, in Dipluridae web, E. Tapia, C. Tapia, N. Dupérré ( QCAZ) .

Etymology. The specific name is in honor of the first author mother Marie-Berthe Girard for her support.

Diagnosis. Males are distiguished from all species by their very short clypeus ( Fig. 51 ). Males most resemble A. anabelleae due to the lack of cusps on metatarsus and tarsus I but can be distinguished by their long and pointed conductor ( Figs 20, 21, 21a ), shorter and angular in the latter species ( Figs 1, 2 ).

Description. Male (holotype): Total length: 0.94; carapace length: 0.37; carapace width: 0.44; abdomen length: 0.57; abdomen width: 0.49; clypeus height: 0.08. Cephalothorax: Carapace orange; pars cephalica puntated, with Y-shaped punctation reaching lateral eyes; cephalic groove shallow, slightly punctated; pars thoracica dorsally rugose, margin slightly punctated ( Fig. 51 ). Sternum orange, suffused with dark gray, punctated, longer than wide and covered with setae. Clypeus orange, punctated. Chelicerae orange, excavated medially; with one basal tooth and denticulate plate apically. Eyes: 6 eyes, rounded; AME absent, ALE separated by their radius, ALE-PLE contiguous, LE-PME separated by their radius, PME contiguous. Abdomen: rounded, with dorsal orange scutum; soft portion whitish without sclerites, laterally suffused with stripes of dark gray; spinneret scutum complete. Legs: Orange; metatarsus I and tarsus I without cusp ( Fig. 22 ); metatarsus II slightly enlarged with one ventral cusp; tarsus II without cusp ( Fig. 23 ). Genitalia: Palpal patella with small anvil-shaped, ventrally curved retrolateral apophysis; palpal tibia with one retrolateral trichobothrium; small scoop-shaped retrolateral apophysis ( Fig. 21 ). Cymbium cup-shaped, without extension ( Figs 20, 21 ). Embolus short not reaching tip of conductor; conductor transparent, faintly ridged, sinuous, pointed ( Figs 20, 21, 21a ).

Female: Unknown.

Distribution. Ecuador: Known only from the type locality.

Natural History. The only two males known were collected at 1,888m.

Remark. One specimen was collected while collecting a Dipluridae web. It is not possible to determine if this species is a kleptoparasite since the specimen was not observed in the web. The specimen could have been collected while collecting debris surrounding the web.
