Agyneta sandia View in CoL new species
Figs 283–290 View FIGURES 283 – 289 View FIGURES 290 – 299 , map 19
Type material: Male holotype from New Mexico, Bernalillo County, Sandia Mountains, C.C. Hoff ( AMNH). EXAMINED.
Etymology: The specific name is a noun in apposition taken from the type locality Sandia Mountains, New Mexico, USA.
Diagnosis: Males are diagnosed from all Agyneta species by their straight, Y-shaped lamella characteristica ( Fig. 283 View FIGURES 283 – 289 ). From other species of the group by the large gap between the dorsal and ventral cymbial tubercles ( Fig. 284 View FIGURES 283 – 289 ), narrower in all other species ( Figs 255 View FIGURES 254 – 264 , 266 View FIGURES 265 – 273 , 275 View FIGURES 274 – 282 ). Females are diagnosed from all Agyneta by their basally narrow proximal part of scape enlarging in a spatula-shaped plate ( Fig. 287 View FIGURES 283 – 289 ). To distinguish it from A. barfoot see diagnosis of the latter.
Description: Male: Total length 1.90; carapace length 0.84, width 0.72.

Distribution: Southwestern USA (Arizona to Texas).
The parva View in CoL group is the largest and includes eleven species, the group contains some Eastern species, A. parva ( Banks 1896) View in CoL , A. evadens ( Chamberlin 1925) View in CoL , A. unimaculata ( Banks 1892) View in CoL , A. barrowsi ( Chamberlin & Ivie 1944) View in CoL , and A. regina ( Chamberlin & Ivie 1944) View in CoL , and some Southwestern species, A. spicula View in CoL n. sp., A. grandcanyon View in CoL n. sp., A. chiricahua View in CoL n. sp., A. crista View in CoL n. sp., A. tuberculata View in CoL n. sp. and A. catalina View in CoL n. sp.
The group is defined by two unique characters. The first is the presence of a prong (serrated or not) at the tip of embolus ( Figs 292 View FIGURES 290 – 299 , 311 View FIGURES 309 – 315 , 318 View FIGURES 316 – 325 , 339 View FIGURES 336 – 345 , 371 View FIGURES 368 – 375 ; note that this prong is not an extension of the embolus proper like in the A. fillmorana View in CoL group). Second, the embolus proper set vertically and not related to the tip of the embolus ( Fig. 292 View FIGURES 290 – 299 ).
Within the group we can easily cluster some similar species, A. parva ( Banks 1896) View in CoL , A. evadens ( Chamberlin 1925) View in CoL , A. unimaculata ( Banks 1892) View in CoL , A. spicula View in CoL n. sp., A. grandcanyon View in CoL n. sp., A. chiricahua View in CoL n. sp. and A. regina ( Chamberlin & Ivie 1944) View in CoL . They all share non-excavated chelicerae without seta-tipped tubercles in males and the none serrated prong at the tip of the embolus.
In A. barrowsi ( Chamberlin & Ivie 1944) View in CoL , A. crista View in CoL n. sp., A. tuberculata View in CoL n. sp. and A. catalina View in CoL n. sp., males have excavated chelicerae with seta-tipped tubercles, a serrated prong at the tip of the embolus ( Figs 356 View FIGURES 354 – 360 , 363 View FIGURES 361 – 367 , 371 View FIGURES 368 – 375 , 378 View FIGURES 376 – 379 ) and an associated prong at the base of the posterior terminal apophysis ( Figs 357 View FIGURES 354 – 360 , 364 View FIGURES 361 – 367 , 372 View FIGURES 368 – 375 , 379 View FIGURES 376 – 379 ).
Members of the parva View in CoL group can be characterized as such, palpal tibia with two retrolateral trichobothria and a dorsal one; very well developed retrolateral and dorsal tibial apophyses ( Fig. 290 View FIGURES 290 – 299 ); embolus with apical prong; Fickert’s gland absent; ventral lamella reduced to absent. Note that the ventral lamella in this group is sometimes difficult to observe. Females have long lateral lobes (sometimes folded) and long stretchers ( Figs 297 View FIGURES 290 – 299 , 314 View FIGURES 309 – 315 , 353 View FIGURES 346 – 353 ).
