Diagnosis: Males can be distinguished from all species by the leaf-like lamella characteristica apically excavated (Fig. 72). From A. decora by the spine-like posterior pocket of paracymbium (Fig. 72), elongated in the latter (Fig. 64). Females can be distinguished from most species by the deep pit hook depression (Fig. 76), from A. rurestris, A. jacksoni, A. nigripes, A. dynica, A. maritima by the presence of parentheses-shaped copulatory ducts visible on the epigynum (Fig. 76).

Cymbium triangular; glabrous depression present (Fig. 72); dorsal cymbial tubercle narrow, rugose; ventral cymbial tubercle triangular, rugose; prolateral notch shallow (Fig. 73). Paracymbium apical pocket short, anterior pocket long and curved making a wide cover, posterior pocket spine-like (Fig. 72). Embolus tip sharp and wide with slight retrolateral extension, one small subapical spine; basal flange with rows of small spines; Fickert’s gland medial, elongated; ventral lamella smooth, pointed; thumb reaching below the embolus proper (Fig. 74). Embolus proper set apically, ventral part wider, with associated short, bifid prong ventrally (Fig. 74). Radix with row of small spines retrolaterally; anterior terminal apophysis narrow with long protrusions; posterior terminal apophysis wide; lamella characteristica large, serrated apically, ending in three large spikes (Fig. 75). Female: Total length 2.09; carapace length 0.82, width 0.57. CEPHALOTHORAX: Same coloration as male. Chelicerae yellowish, not excavated; promargin two teeth, retromargin one denticle. Cheliceral stridulatory organ ~46 striae, narrowly spaced throughout. ABDOMEN: Same as male. LEGS: Same as male; palpal tarsus inflated, claw absent; leg I total length: 1.86; leg III total length: 1.66; Tm I: 0.80, Tm IV: present. GENITALIA: Epigynum with proximal part of scape wide, sides straight; epigynal slits long and oval; pit hook depression deep (Fig. 76); lateral lobes intermediate; stretcher and pit small (Fig. 77). Median part of scape long and wide; genital pores situated at base of lateral lobes pockets (Fig. 78). Internal genitalia with a large, elongated receptacula set obliquely (Figs 77, 78). Distribution: Holarctic.
