Materials Examined
Type material:Micryphantes rurestris C.L. Koch 1836, 3 HOLOTYPE, (ZMHU). NOT EXAMINED.
Diagnosis
Diagnosis: Males can be distinguished from most Agyneta species by their L-shaped lamella characteristica (Fig. 108). From A. jacksoni and A. nigripes by their more elongated and pointed cymbial dorsal tubercle (Fig. 109), rounded in A. jacksoni (Fig. 117) and short in A. nigripes (Fig. 124). Females are differentiated from most Agyneta by their deep pit hook depression (Fig. 112). From A. maritima and A. dynica by the longer sides of the proximal part of scape (Fig. 112), shorter in A. maritima and A. dynica (Figs 134, 141) and from A. nigripes by the straight sides proximal part of scape (Fig. 112), oblique in the latter (Fig. 127). The differentiation between females of A. rurestris, A. jacksoni is problematic, it is advisable to take into account the distribution and association with males.
Description
Description: Male: Total length 2.24; carapace length 1.03, width 0.77.
CEPHALOTHORAX: Carapace dark orange-brown, shiny, finely reticulate; suffused with gray along margin, radiating lines. Sternum brown suffused with gray. Clypeus height 2. Chelicerae orange, apical part lighter, excavated; ~ 16 seta-tipped tubercles; promargin four denticles, retromargin four tiny denticles joined together, both margins with rounded projections near base of fang. Cheliceral stridulatory organ ~ 50 striae, widely spaced apically and gradually getting closer. ABDOMEN: Uniformly light to dark gray. LEGS: Light yellow; leg I total length: 3.77; leg III total length: 2.64; Tm I: 0.23, Tm IV: absent. GENITALIA: Palpal retrolateral tibial apophysis short, rugose; dorsal tibial apophysis wide and rugose; two retrolateral trichobothria and a dorsal one (Figs 13, 108). Cymbium triangular; glabrous depression present (Fig. 108); dorsal cymbial tubercle pointed, smooth; ventral tubercle absent; prolateral notch shallow (Figs 14, 109). Paracymbium apical pocket short, anterior and posterior pockets short and curved (Fig. 108). Embolus tip wide and pointed; ventro-basally spiny; basally with spur and small spines; Fickert’s gland absent; ventral lamella thin and serrated; thumb short, well below the embolus proper (Fig. 110). Embolus proper set apically, anterior part slightly serrated (Fig. 110). Anterior terminal apophysis wide with numerous short protrusions; posterior terminal apophysis wide, striated; lamella characteristica large, with row of spurs and ending in two large, sharp points (Fig. 111). Female: Total length 2.15; carapace length 0.91, width 0.65. CEPHALOTHORAX: Same coloration as male. Chelicerae yellow; promargin five teeth, retromargin five denticles. Cheliceral stridulatory organ visible ~ 40 striae, well spaced apically and narrowly spaced basally. ABDOMEN: Same as male. LEGS: Same as in male; palpal tibia and tarsus brownish, tarsal claw absent; leg I total length: 3.06; leg III total length: 2.24; Tm I: 0.28, Tm IV: absent. GENITALIA: Epigynum with wide proximal part of scape, straight, vertical sides; epigynal slits oval and short; pit hook depression deep (Fig. 112); lateral lobes wide and short, folded; stretcher and pit small (Fig. 114). Median part of scape long, wider apically; genital pores situated at base of lateral lobes pockets (Fig. 114). Internal genitalia with a rounded ventral receptacula and a small oval dorsal one (Figs 113, 115).

Distribution
Distribution: West Palearctic (Tanasevitch 2009). Note:Meioneta rurestris is the only Palearctic species included in the revision, seeing that it is the typespecies of the genus Meioneta being synonymized under Agyneta.
