Type material: Meioneta regina Chamberlin & Ivie 1944, Ƥ HOLOTYPE from Georgia: 3 miles SE of Savannah, W 81º4’:N 32º4’, April 8, 1943, W. Ivie collector (AMNH). EXAMINED.
Diagnosis: Males are diagnosed from all other species by their large footh-shaped dorsal cymbial tubercle and triangular ventral cymbial tubercle (Fig. 347). Females are diagnosed from all other Agyneta by their broad median part of scape (Fig. 352).
Description: Male: Total length 1.52; carapace length 0.69, width 0.51.
CEPHALOTHORAX: Carapace light orange-brown, shiny, finely reticulate; suffused with gray margin and radiating lines; sometimes with trident mark. Sternum suffused with gray, darker along margins. Clypeus height 2. Chelicerae light orange-brown; not excavated; seta-tipped tubercles absent; promargin five denticles, retromargin four tiny denticles. Cheliceral stridulatory organ ~16 striae, well spaced throughout. ABDOMEN: Uniformly light gray. LEGS: Light yellow-brown; leg I total length: 2.76; leg III total length: 1.82; Tm I: 0.22; Tm IV: absent. GENITALIA: Palpal retrolateral tibial apophysis long, rugose; dorsal tibial apophysis wide, rounded and smooth; two retrolateral trichobothria and one dorsal (Fig. 346). Cymbium rounded; glabrous depression present (Fig. 346); dorsal tubercle wide, squared and rugose; ventral tubercle long, pointed and smooth; prolateral notch shallow (Fig. 347). Paracymbium apical pocket short, anterior pocket medium, posterior pocket absent (Fig. 346). Embolus tip wide and pointed, with long prong; ventrally rugose; Fickert’s gland absent; ventral lamella absent; thumb reaching the embolus proper tip (Fig. 348). Embolus proper set apically, of equal part (Fig. 348). Anterior terminal apophysis narrow with medial spine and numerous short protrusions, basally with one elongated spur-like prong and one large, blunt one; terminal apophysis long, tip curved; lamella characteristica elongated with wide serrated tip (Fig. 349).
Female: Total length 1.83; carapace length 0.66, width 0.52
CEPHALOTHORAX: Same coloration as male. Clypeus height 2. Chelicerae light orange-brown; promargin six teeth, retromargin five denticles. Cheliceral stridulatory organ visible ~13 striae, well spaced throughout. ABDOMEN: Uniformly light gray. LEGS: Same as in male; palpal segment darker orange-brown, tarsal claw absent; leg I total length: 2.72; leg III total length: 1.80; Tm I: 0.29, Tm IV: absent. GENITALIA: Epigynum with wide, straight, enlarging proximal part of scape; epigynal slits large and oval; pit hook depression indistinguishable (Fig. 350); lateral lobes folded (Fig. 351); stretcher very long; pit deep (Fig. 353). Median part of scape extremely wide (Fig. 352); genital pores situated at base of lateral lobes pockets (Fig. 353). Internal genitalia with a rounded ventral receptacula and an oval dorsal one (Figs 352, 353).
