Type material: Bathyphantes micaria Emerton 1882 , 3 HOLOTYPE from New Haven, Conn., Oct. 1881. J.H. Emerton Coll. (unique number 22060). MCZ, EXAMINED.

Diagnosis: Males and females can be easily separated from all other species in the genus by their abdominal patterns ( Figs 384, 385 View FIGURES 380 – 389 ). Males can be distinguished from all other species by the narrow, pointed dorsal cymbial tubercle and the squared ventral cymbial tubercle ( Fig. 381 View FIGURES 380 – 389 ). Females are distinguished from all Agyneta by their wide, with rounded sides proximal part of scape ( Fig. 386 View FIGURES 380 – 389 ).

Description: Male: Total length 1.82; carapace length 0.77, width 0.59.

CEPHALOTHORAX: Carapace brown, shiny, finely reticulate; suffused with gray along radiating lines and margin; trident mark present. Sternum, yellow suffused with gray, darker along margin. Clypeus height 2. Chelicerae light yellow, sometimes with dark gray V-band medially, excavated; ~ 10 seta-tipped tubercles; promargin four teeth, retromargin four tiny denticles and a projection near base of fang. Cheliceral stridulatory organ visible ~26 striae, well spaced. ABDOMEN: Patterned, with apical and basal dark, wide bands, flanking an off-white middle portion or apical and basal dark bands reduced ( Fig. 384 View FIGURES 380 – 389 ). LEGS: Light yellow, coxae with dark mark apically, tip of femurs and metatarsus I-IV with dark gray marks; leg I total length: 3.16; leg III total length: 2.13; Tm I: 0.31, Tm IV: absent. GENITALIA: Palpal tibia with large, smooth retrolateral tibial apophysis; dorsal tibial apophysis absent; two retrolateral and one dorsal trichobothria ( Fig. 380 View FIGURES 380 – 389 ). Cymbium expanded into a conical apex; glabrous depression present ( Fig. 380 View FIGURES 380 – 389 ); dorsal cymbial tubercle smooth and pointed; ventral tubercle large, rugose; prolateral notch very deep ( Fig. 381 View FIGURES 380 – 389 ). Paracymbium apical pocket medium, anterior pocket long and curved, posterior pocket absent ( Fig. 380 View FIGURES 380 – 389 ). Embolus tip curved, rounded; small spines basally and ventrally; Fickert’s gland absent; ventral lamella absent; thumb long going beyond the embolus proper ( Fig. 382 View FIGURES 380 – 389 ). Embolus proper set medially with bifid prong near base ( Fig. 382 View FIGURES 380 – 389 ). Anterior terminal apophysis curved with long protrusions; posterior terminal apophysis large, well sclerotized; lamella characteristica long, with squared tip and basal prong ( Fig. 383 View FIGURES 380 – 389 ).

Female: Total length 1.91; carapace length 0.71, width 0.59.

CEPHALOTHORAX: Same as in male. Chelicerae promargin five teeth, retromargin five denticles. Cheliceral stridulatory organ ~18 striae, well spaced. ABDOMEN: Patterned, off-white with two vertical dark bands lateroapically and latero-basally or two vertical dark bands latero-apically with two dark spots medially and a zigzag dark bands basally ( Fig. 385 View FIGURES 380 – 389 ). LEGS: Light yellow, coxae apical mark, the tip of femurs, metatarsus and tarsus I-IV with dark gray marks, palpal femur and tibia with dark gray, palpal tarsus without claw; leg I total length: 3.92; leg III total length: 2.32; Tm I: 0.31, Tm IV: absent. GENITALIA: Epigynum with wide proximal part of scape with rounded sides; epigynal slits oval; pit hook depression absent ( Fig. 386 View FIGURES 380 – 389 ); lateral lobes medium ( Fig. 387 View FIGURES 380 – 389 ); stretcher small: pit medium ( Fig. 389 View FIGURES 380 – 389 ). Median part of scape long; genital pores situated at base of lateral lobes ( Figs 388, 389 View FIGURES 380 – 389 ). Internal genitalia with elongated, curved receptacula ( Figs 387, 388 View FIGURES 380 – 389 ).
