RTA with a large dorsal branch, distally pointed and strongly sclerotized; lateral branch forming sclerotized finger-shaped appendix; ventrally bearing a weakly developed rounded ridge. Embolus originating (free apex) between 7 and 8 o’clock position; length (only the free apex) slightly more than twice cymbium width; distal tip between 3 and 4 o’clock position. Conductor lamella-like, distally elongated (parallel to cymbium), arcuated and laterally folded along the whole length; as long as alveolus, distally reaching beyond alveolus margin; terminal end forming sclerotized peak, pointing ventrally (in lateral view). Connection of conductor and tegulum membranous. Median apophysis consisting of membranous base and thin and broad sclerotized distal plate, pocket-like; originating between 4 and 5 o’clock position; protruding ventrally; basis as wide as median apophysis length. Tegular apophysis absent. Prosoma length: 6.78 mm. Opisthosoma length: 5.82 mm.
Epigynal plate sclerotized with a distinct atrium, reversed trapezoid in shape; anterior margin of atrium continuous change from sclerotized epigynal plate to membranous white skin. Ground plate of the atrium transversally divided: anterior part membranous and oval; posterior part forming strongly sclerotized semicircular bar. Receptacula visible through plate. Copulatory openings barely visible as gaps, located medial of atrium. Receptacula large, globular, touching each other; fertilization ducts very long and strongly convoluted. Prosoma length: 5.30 mm. Opisthosoma length: 6.00 mm.
Eyes: In frontal view PER procurved and AER slightly procurved. Diameters: PME: 0.19–0.23; PLE: 0.21–0.31; AME: 0.19–0.29; ALE: 0.29. Distances: PME–PME equal to diameter of PME; PME–PLE more than diameter of PME; PME–ALE about 1.5 diameter of PME. Clypeus height (measured under AME) less than 2.5 times diameter of AME; (measured under ALE) about 1.5 times diameter of ALE.
Coloration: two longitudinal symmetric darkened bands on carapace, interrupted and sometimes reduced to triangular dots, intensified by white and black plumose hairs. Opisthosoma with red-brown median band, slightly paler than in A. ligurica.
Additional somatic characters: Distal segment of PLS slightly longer than basal segment, both very weakly darkened.
