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). Males can be distinguished from all other species by the narrow, pointed dorsal cymbial tubercle and the squared ventral cymbial tubercle (Fig. 381). Females are distinguished from all Agyneta by their wide, with rounded sides proximal part of scape (Fig. 386).

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). 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). Cymbium expanded into a conical apex; glabrous depression present (Fig. 380); dorsal cymbial tubercle smooth and pointed; ventral tubercle large, rugose; prolateral notch very deep (Fig. 381). Paracymbium apical pocket medium, anterior pocket long and curved, posterior pocket absent (Fig. 380). 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). Embolus proper set medially with bifid prong near base (Fig. 382). Anterior terminal apophysis curved with long protrusions; posterior terminal apophysis large, well sclerotized; lamella characteristica long, with squared tip and basal prong (Fig. 383).

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). 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); lateral lobes medium (Fig. 387); stretcher small: pit medium (Fig. 389).
