Ubick, W. Savary, K. Dabney ( CAS ). EXAMINED . Etymology: The specific name is an adjective in reference to the long spines arising from the retro-ventral surface of the embolus. Diagnosis: Male are diagnosed from all Agyneta by the pointed, strongly rugose dorsal cymbial tubercle ( Fig. 198 ), from members of the species group by the short spine-like posterior pocket of the paracymbium ( Fig. 197 ) absent, rounded or elongated in other species of the group ( Figs 172 , 185 , 195 , 202 , 209 ). Description: Male : Total length 2.32; carapace length 1.05, width 0.80. CEPHALOTHORAX: Carapace light brown, shiny, finely reticulate; lightly suffused with dark gray along radiating lines, pars cephalica and margin. Sternum completely suffused with dark gray. Clypeus height 3. Chelicerae orange, not excavated; promargin three denticles, retromargin two tiny denticles. Cheliceral stridulatory organ easily visible ~36 striae, well spaced. ABDOMEN: Dark gray, with off-white marks ( Fig. 201 ). LEGS: Light yellow; leg I total length: 4.39; leg III total length: 2.93; Tm I: 0.25, Tm IV: absent. GENITALIA: Palpal retrolateral tibial apophysis reduced, small and triangular; dorsal tibial apophysis rugose; one retrolateral and one dorsal trichobothria ( Fig. 197 ). Cymbium with retrolateral fold; glabrous depression present ( Fig. 197 ); dorsal cymbial tubercle rugose and pointed; ventral tubercle small, triangular; prolateral notch shallow ( Fig. 198 ). Paracymbium apical pocket small, anterior pocket absent, posterior pocket spine-like ( Fig. 197 ). Embolus tip pointed; tiny spines ventrally; large spikes retro-ventrally; Fickert’s gland medial, bulbous; ventral lamella basally enlarged into a plate with spines, extending on the retrolateral side of the embolus all the way to the embolus proper, with a row of spines; thumb just reaching the base of embolus proper ( Fig. 199 ). Embolus proper set apically, anterior part serrated reaching the tip of the embolus ( Fig. 199 ). Anterior terminal apophysis long, with numerous, long plumose protrusions; posterior terminal apophysis twisted with one small spine basally; lamella characteristica basally with a twisted branch and a long, dentate curved projection ( Fig. 200 ). Female : Unknown. Other material examined: USA : California : San Ardo, 1955, 13, McDonald , Blodget ( AMNH ). Distribution: California, USA .
