Type material: Microneta lophophor Chamberlin & Ivie 1933 , Ƥ HOLOTYPE from South Fork of Raft River ( AMNH). Not found. NOT EXAMINED.
Diagnosis: Males are diagnosed from all Agyneta by their elongated lamella characteristica, reaching the tip of the cymbium ( Fig 450 View FIGURES 450 – 458 ), from A. girardi , by their large, angular embolus ( Fig. 452 View FIGURES 450 – 458 ), rounded in the latter ( Fig. 460 View FIGURES 459 – 465 ). Females are diagnosed from all species by their extremely large epigynal slits with lateral lobes not filling the furrows ( Fig. 455 View FIGURES 450 – 458 ), from A. girardi by the extremely long lateral lobes ( Fig. 457 View FIGURES 450 – 458 ), much shorter in the latter ( Fig. 465 View FIGURES 459 – 465 ).

Description: Male: Total length 1.79; carapace length 0.78, width 0.65.
CEPHALOTHORAX: Carapace light yellow-orange, shiny, finely reticulate; margin, radiating lines and pars cephalica lightly suffused with dark gray; trident mark present. Clypeus height 2. Sternum strongly suffused with dark gray. Chelicerae light yellow-orange, excavated, transversely suffused with gray; ~ 23 seta-tipped tubercles; promargin three teeth, retromargin three denticles, both margins with projection near base of fang. Cheliceral stridulatory organ ~ 38 striae, well spaced throughout. ABDOMEN: Uniformly light to dark gray. LEGS: Light yellow; leg I total length: 3.11; leg III total length: 2.22; Tm I: 0.27, Tm IV: absent. GENITALIA: Palpal retrolateral tibial and dorsal tibial apophysis absent; two retrolateral trichobothria and a dorsal one ( Fig. 450 View FIGURES 450 – 458 ). Cymbium rounded; glabrous depression present ( Fig. 450 View FIGURES 450 – 458 ); cymbial turbercles absent; prolateral notch absent ( Fig. 451 View FIGURES 450 – 458 ). Paracymbium apical pocket small, anterior pocket small and curved, posterior pocket small, spine-like ( Fig. 450 View FIGURES 450 – 458 ). Embolus tip pointed; base of embolus enlarged with large spur; apico-ventrally with large process; Fickert’s gland bulbous, set medially; ventral lamella large, transparent and serrated; thumb large, reaching well beyond the embolus proper ( Fig. 453 View FIGURES 450 – 458 ). Embolus proper set apically on a short horizontal ridge, of equal part ( Fig. 453 View FIGURES 450 – 458 ). Anterior terminal apophysis long with a few long protrusions; posterior terminal apophysis tip twisted, base striated; lamella characteristica long and thin, with median triangular extension ( Fig. 454 View FIGURES 450 – 458 ).
Female: Total length 2.11; carapace length 0.83, width 0.61.
CEPHALOTHORAX: Same as in male. Chelicerae promargin five teeth, retromargin four teeth. Cheliceral stridulatory organ ~29 striae, well spaced. ABDOMEN: Same coloration as male. LEGS: Same coloration as male; palpal tarsal claw absent, palpal tibia and metatarsus suffused with dark gray; leg I total length: 2.98; leg III total length: 2.24; Tm I: 0.24, Tm IV: absent. GENITALIA: Epigynum with narrow proximal part of scape constricted medially; epigynal slits extremely large; pit hook depression shallow and wide ( Fig. 455 View FIGURES 450 – 458 ); lateral lobes long, not filling the epigynal slits; stretcher indistiguishable; pit small ( Figs 455, 457 View FIGURES 450 – 458 ). Median part of scape narrow; genital pores situated in the middle of lateral lobes ( Figs 457, 458 View FIGURES 450 – 458 ). Internal genitalia with large oval ventral receptacula and a small dorsal one ( Figs 456, 457 View FIGURES 450 – 458 ).
