Crawford ( UWBM ). EXAMINED . Etymology: The specific name is a patronym in honor of Don Buckle for his contribution to Linyphiidae taxonomy, and for his support and friendship. Diagnosis: Males are diagnosed from all species by the large, rugose and squared dorsal cymbial tubercle ( Fig. 203 ). Females are distinguished from all species by the narrow, dark proximal part of scape ( Fig. 206 ). From A. fillmorana and A. darrelli , by the vertical sides of the proximal part of scape ( Fig. 206 ), oblique in A. fillmorana and A. darrelli (Figs 181, 191). Description: Male : Total length 2.20; carapace length 1.00, width 0.76. CEPHALOTHORAX: Carapace orange, shiny, finely reticulate; lightly suffused with dark gray along radiating lines, pars cephalica and margin. Sternum completely suffused with dark gray. Clypeus height 2. Chelicerae orange; not excavated; seta-tipped tubercles absent; promargin three denticles, retromargin two tiny denticles. Cheliceral stridulatory organ easily visible ~20 striae, well spaced. ABDOMEN: Uniformly light to dark gray. LEGS: Light orange; leg I total length: 4.81; leg III total length: 3.43; Tm I: 0.27, Tm IV: absent. GENITALIA: Palpal retrolateral tibial apophysis absent; dorsal tibial apophysis triangular, rugose; one retrolateral and one dorsal trichobothria ( Fig. 202 ). Cymbium with retrolateral fold; glabrous depression present ( Fig. 202 ); dorsal cymbial tubercle large and square; ventral cymbial tubercle absent; prolateral notch shallow ( Fig. 203 ). Paracymbium apical pocket small, anterior pocket absent, posterior pocket small and rounded ( Fig. 202 ). Embolus tip pointed; tiny spines apically and basally; large spikes retro-ventrally; Fickert’s gland medial, bulbous; ventral lamella enlarged basally into a plate with small short spines, extending on the retrolateral side of the embolus all the way to the the embolus proper, with a row of spines; thumb short not reaching the embolus proper ( Fig. 204 ). Embolus proper set apically, serrated, crest-like, reaching the tip of embolus ( Fig. 204 ). Anterior terminal apophysis extremely wide with numerous, long protrusions; posterior terminal apophysis with sclerotized tip with ridges and an elongated prong basally; lamella characteristica narrow, with dentate curved tip, somewhat transparent ( Fig. 205 ). Female : Total length 1.97; carapace length 0.89, width 0.68. MAP. 13. Localities of Agyneta bucklei n. sp. CEPHALOTHORAX: Same coloration as male. Chelicerae promargin five denticles, retromargin five tiny denticles. Cheliceral stridulatory organ easily visible ~9 striae, well spaced. ABDOMEN: Same as male. LEGS: Same as male; palpal tarsal claw absent; leg I total length: 4.39; leg III total length: 3.61; Tm I: 0.21, Tm IV: absent. GENITALIA: Epigynum with narrow, dark proximal part of scape with vertical sides; epigynal slits oval; pit hook depression shallow ( Fig. 206 ); lateral lobes very short and wide; stretcher medium; pit deep ( Fig. 207 ). Median part of scape narrow basally, widening apically; genital pores located at base of lateral lobes pockets ( Fig. 208 ). Internal genitalia with a small, rounded receptacula ventrally and large, rounded receptacula dorsally ( Figs 207, 208 ).
