Menemerus errabundus

description: Menemerus errabundus sp. n. (Figs. 1–6)
Types: Holotype d (BMNH) from Iran, Khuzestan, Shush (Susa) (c. 32.20°N, 48.25°E), running on walls of shady mill stream tunnel, 18 September 1958, coll.? Paratypes: 2d 6♀ (BMNH), together with holotype.
Etymology: From the Latin ‘‘ errabundus ’’, meaning ‘‘vagrant’’.
Diagnosis: The male of Menemerus errabundus sp. n. is most similar to those of M. guttatus Wesołowska, 1999 from Morocco (see Wesołowska, 1999: figs. 143–145) and M. modestus Wesołowska, 1999 from Tunisia (see Wesołowska, 1999: figs. 210–212), but can readily be distinguished from both by the conformation of the embolar division, particularly by the shape of the distal lamella (arrowed in Fig. 1), and the mutual arrangement and shapes of the tibial apophyses (Figs. 1–3). The female of the new species is most similar to those of M. animatus O. Pickard-Cambridge, 1876 from northern Africa and the Mediterranean (see Wesołowska, 1999: figs. 16–21; and Metzner, 1999: fig. 108) and M. davidi Prószyński & Wesołowska, 1999 from NE Africa and the Levant (see Wesołowska, 1999: figs. 86–89), but di ff ers from both in having a wider and relatively deep epigynal pocket (Fig. 4) and in the mutual arrangement of the insemination ducts and receptacles (Fig. 5).
Distribution: The type locality only.
Description: Male (holotype): Measurements: Carapace 2.40 long, 1.70 wide, 0.88 high at PLE. Ocular area 1.18 long, 1.40 wide anteriorly and 1.38 wide posteriorly. Diameter of AME 0.48.

Coloration: Carapace brown, with yellow triangular spot behind PLEs, densely covered with white (on eye field and medial yellow figure) and brown (on sides) hairs. Clypeus brown, densely covered with white hairs. Sternum yellow. Maxillae, labium and chelicerae brown. Abdomen light yellow, but dorsum with pale brown pattern of two lateral interrupted stripes and an elongated cardial spot. Book-lung covers light yellow. Spinnerets yellow, tinged with brown. All legs light yellow. Palps brown, structure as in Figs. 1–3.
Female (paratype): Measurements: Carapace 2.56 long, 1.76 wide, 0.98 high at PLE. Ocular area 1.35 long, 1.58 wide anteriorly and 1.55 wide posteriorly. Diameter of AME 0.53. Abdomen 3.20 long, 2.25 wide. Cheliceral length 0.88. Clypeal height 0.05. Length of leg segments: I 1.53+ 0.90+0.85+0.88+0.55; II 1.38+0.78+0.88+ 0.80+0.55; III 1.38+0.65+0.88 +1.03 +0.60; IV 1.70+ 0.88+1.33 +1.25+0.65. Leg spination: leg I: Fm d 0-1- 1-2; Tb pr 0-1, v 2-2 -2ap; Mt v 2-2 ap; leg II: Fm d 1-1-2; Tb v 1 -0-1ap; Mt v 2-2 ap; leg III: Fm d 1-1-2; Tb pr and rt 1-1, v 1 -0-2ap; Mt pr and rt 2ap, v 2 -0-2ap; leg IV: Fm d 1-1-2; Tb pr and rt 1-1, v 1 -0-2ap; Mt pr and rt 2ap, v 2 -0-2ap. Coloration: As in male, but di ff ers as follows: labium, maxillae and chelicerae light brown (almost yellow); palps light yellow; all legs yellow with pale brown semi-rings at segment ends. Epigyne and spermathecae as in Figs. 4–6.
