Agyneta ordinaria (Chamberlin & Ivie 1947) Figs 474–480, map 32 Meioneta ordinaria Chamberlin & Ivie 1947: 59, f. 74–75. (Description Ƥ). Agyneta ordinaria Buckle et al. 2001: 101. (Transferred from Meioneta). Type material: Meioneta ordinaria Chamberlin & Ivie 1947, Ƥ HOLOTYPE from Alaska, Haines, August 25, 1945, J.C. Chamberlin (AMNH). Not found, NOT EXAMINED. Diagnosis: Males are distinguished from all Agyneta species by their extremely long ventral cymbial tubercle (Fig. 475). Females are distinguished from most species by the parallel sides of the proximal part of scape (Fig. 478), from A. manni by their rounded receptacula (Fig. 480), elongated in the latter (Fig. 490). Description: Male: Total length 1.79; carapace length 0.83, width 0.64. CEPHALOTHORAX: Carapace dark orange-brown, shiny, finely reticulate; suffused with dark gray along margin, radiating lines; trident mark present. Sternum orange-brown suffused with dark gray. Clypeus height 2. Chelicerae orange-brown, with transverse gray band, excavated; ~15 seta-tipped tubercles; promargin four teeth, retromargin four denticles, both margins with rounded projections near base of fang. Cheliceral stridulatory organ ~30 strong striae, well spaced, gradually getting closer basally. ABDOMEN: Uniformly dark gray. LEGS: Orange, patella and tarsus light orange; leg I total length: 3.02; leg III total length: 2.22; Tm I: 0.20, Tm IV: absent. GENITALIA: Palpal retrolateral tibial apophysis pointed, rugose; dorsal tibial apophysis absent; two retrolateral trichobothria and one dorsal (Fig. 474). Cymbium triangular; glabrous depression present (Fig. 474); dorsal cymbial tubercle small, rounded; ventral tubercle elongated, rounded and rugose; prolateral notch shallow (Fig. 475). Paracymbium apical pocket short, anterior pocket curved making a large cover, posterior pocket absent (Fig. 474). Embolus tip pointed; Fickert’s gland elongated situated medially; ventral lamella transparent, spiny; thumb short, reaching below the embolus proper (Fig. 476). Embolus proper set apically, of equal part, associated with embolus tip (Fig. 476). Anterior terminal apophysis with wide tip with a few protrusions; posterior terminal apophysis small, not well sclerotized; lamella characteristica large, with two fold, one small, serrated and one with pointed tip (Fig. 477). Female: Total length 1.78; carapace length 0.74, width 0.58. MAP. 32.

CEPHALOTHORAX: Same coloration as male. Chelicerae yellowish; promargin four teeth, retromargin one denticle. Cheliceral stridulatory organ ~26 striae, well spaced slowly getting closer basally. ABDOMEN: Same as male. LEGS: Same as male; palpal claw absent; leg I total length: 2.81; leg III total length: 2.19; Tm I: 0.23, Tm IV: absent. GENITALIA: Epigynum with proximal part of scape wide, sides parallel; epigynal slits small; pit hook depression deep (Fig. 478); lateral lobes medium; stretcher indiscernible; pit deep (Fig. 479). Median part of scape long, narrow; genital pores situated at base of lateral lobes pockets (Fig. 480). Internal genitalia with large, rounded receptacula (Figs 479, 480).

Notes: Despite the fact that the female holotype was not found, and no specimens from the type locality or from Alaska were studied, I feel confident that the specimen described here represents the right species, based on Chamberlin & Ivie 1947 description and illustrations (figs. 74-75).
