EXAMINED . Etymology: The specific name is a noun in apposition taken from the type locality, Bronx , New York, USA . FIGURES 432–438. Agyneta bronx n. sp. 432–435, Male. 436–438, Female. 432.

Diagnosis: Males are distinguised from all species by their large double triangular-shaped dorsal cymbial tubercle ( Fig. 433 ), from A. llanoensis by the long, sinuous lamella characteristica ( Fig. 432 ), short in the latter ( Fig. 425 ). Females are diagnosed from all Agyneta by their by the diverging copulatory ducts visible on the proximal part of scape ( Fig. 436 ), from a A. llanoensis , see diagnosis of the latter. Description: Male : Total length 1.85; carapace length 0.88, width 0.76. CEPHALOTHORAX: Carapace light yellow, shiny, finely reticulate. Sternum light yellow, slightly suffused with dark gray. Clypeus height 3. Chelicerae light orange, not excavated; seta-tipped tubercles absent; promargin five teeth, retromargin four denticles, retromargin with triangular projection near base of fang. Cheliceral stridulatory organ ~52 strong striae, well spaced, getting closer basally. ABDOMEN: Uniformly offwhite. LEGS: Light yellow; leg I total length: 4.18; leg III total length: 2.32; Tm I: 0.23, Tm IV: absent. GENITALIA: Palpal retrolateral tibial apophysis large, pointed, rugose; dorsal tibial apophysis rugose; two retrolateral trichobothria and one dorsal ( Fig. 432 ). Cymbium triangular; glabrous depression present ( Fig. 432 ); dorsal cymbial tubercle with two triangular tips, rugose; ventral tubercle, rounded and striated; prolateral notch deep ( Fig. 433 ). Paracymbium apical pocket long, anterior pocket long and curved making a small cover, posterior pocket medium ( Fig. 432 ). Embolus tip wide, no retrolateral extension; basally with row of spines; ventrally with numerous small spines; Fickert’s gland globulous situated medially; ventral lamella reduced or absent; thumb going slightly over the embolus proper ( Fig. 434 ). Embolus proper set apically, dorsal part wider, not serrated with associated large dentate prong ( Fig. 434 ). Anterior terminal apophysis wide with numerous, long protrusions and one large spike basally; posterior terminal apophysis short with three spines; lamella characteristica large and elaborate ( Fig. 435 ). Female : Total length 1.99; carapace length 0.83, width 0.41. MAP. 29. Localities of Agyneta bronx n. sp. , Agyneta paquini n. sp. , Agyneta serrata ( Emerton 1909 ) . CEPHALOTHORAX: Same coloration as male. Chelicerae yellow; promargin five teeth, retromargin four denticles. Cheliceral stridulatory organ ~37 striae, well spaced getting closer basally.
