(unique number 22544). MCZ , EXAMINED . Diagnosis: Males and females are recognized by their abdominal pattern ( Figs 294, 295 ). Furthermore, males are diagnosed from all Agyneta by their large palpal retrolateral tibial apophysis, and dorsal tibial apophysis with two pointed tip ( Fig. 290 ). From A. evadens and A. unimaculata by the presence of three large prongs at the base of the embolus ( Fig. 292 ). Females are diagnosed from all species by their narrow proximal part of scape enlarging in a large rectangular plate ( Fig. 296 ). From A. evadens and A. unimaculata by their deep pit hook depression ( Fig. 296 ), absent in A. evadens and A. unimaculata ( Figs 306 , 313 ) Description: Male : Total length 1.53; carapace length 0.72, width 0.55. CEPHALOTHORAX: Carapace orange-brown, shiny, finely reticulate; lightly suffused with light gray along radiating lines, pars cephalica and margin. Sternum lightly suffused with gray. Clypeus height 2. Chelicerae orange, not excavated; seta-tipped tubercles absent; promargin four denticles, retromargin three tiny denticles. Cheliceral stridulatory organ easily visible ~17 striae, well spaced throughout. ABDOMEN: Patterned with large gray apical band and three gray chevrons ( Fig. 294 ) or uniformly light to dark gray. LEGS: Light orange; leg I total length: 2.92; leg III total length: 2.02; Tm I: 0.21, TmIV: absent. GENITALIA: Palpal retrolateral tibial apophysis large with one large pointed tip and a small one; dorsal tibial apophysis wide, curved with two pointed tip; two retrolateral trichobothria and a dorsal one ( Fig. 290 ). Cymbium rounded; glabrous depression present ( Fig. 290 ); dorsal cymbial tubercle rounded, rugose; ventral tubercle absent; prolateral notch shallow ( Fig. 291 ). Paracymbium with apical, anterior and posterior pockets long ( Fig. 290 ). Embolus tip wide, rounded with large bifid prong, basally with three large prongs; Fickert’s gland absent; ventral lamella, rugose with large spikes basally; thumb reaching just over the embolus proper ( Fig. 292 ). Embolus proper set apically, on a vertical ridge, of equal part ( Fig. 292 ). Anterior terminal apophysis wide with numerous curved protrusions; posterior terminal apophysis fused to lamella characteristica, short and squared; lamella characteristica with two branches, one with small pointed tip, one large and rugose ( Fig. 293 ). Female : Total length 1.56; carapace length 0.70, width 0.55. CEPHALOTHORAX: Coloration, same as male. Clypeus height 2. Chelicerae orange, promargin five denticles; retromargin three tiny denticles. Cheliceral stridulatory organ easily visible ~10 striae, well spaced throughout. ABDOMEN: Patterned with large gray apical band and three gray chevrons ( Fig. 295 ) or uniformly light to dark gray. LEGS: Light orange; leg I total length: 2.90; leg III total length: 2.05; Tm I: 0.23; Tm IV: absent, palpal tarsal claw absent. GENITALIA: Epigynum with very narrow anterior part of proximal part of scape, enlarging in a large rectangular plate; epigynal slits more or less oval not reaching the base of the epigynum; pit hook depression deep ( Fig. 296 ); lateral lobes long; stretcher long; pit small ( Fig. 297 ). Median part of scape wide, narrowed medially; genital pores located at base of lateral lobes pockets ( Fig. 298 ). Internal genitalia with elongated ventral receptacula, dorsal receptacula oval ( Figs 297, 298 ).
