Etymology: The specific name comes from a Latin word, virgulatus, meaning “with stripes”, referring to the distinctively striated carapace.
Diagnosis: The new species can be distinguished from all the other congeners by the distinctively striated carapace, the rows of small pits on well developed radial furrows in sternum (Fig. 1F), the smaller eyes size and the knob-like elevation on proximo-ventral surface of male palpal bulb (Fig. 4B).
Description: Male. Body reddish brown, chelicerae and sternum lighter, legs yellow. Body length 2.77–2.97; carapace 1.20–1.26 length, 0.83–0.88 width; abdomen 1.37–1.57 length, 0.91–1.03 width. Clypeus with a row of hairs at anterior margin; clypeus height about 1 time the diameter of anterior eyes. Pars cephalica slightly elevated in profile (Fig. 1E). Carapace smooth on the top and distinctively striated at sides (Fig. 1D), with a row of finely hairs along margin, its dorsal surface with a row of short, finely hairs laterally and several directed hairs medially. Eyes six, nearly equal sized, distinctively smaller than those of the congeners (compare Figs 1 D and 1A, G, J); ALE separated by about its diameter; posterior eye row slightly recurved in dorsal view. Labium with 2 setae at anterior margin. Sternum with narrow, transverse palpal groove, covered with thin hairs standing in medium-sized, round pits; radial furrows well developed, composing of rows of small pits (Fig. 1F). Measurements of legs: I 2.96 (0.91, 0.51, 0.63, 0.57, 0.34); II 2.82 (0.86, 0.48, 0.57, 0.57, 0.34); III 2.40 (0.80, 0.37, 0.43, 0.46, 0.34); IV 3.26 (1.00, 0.49, 0.71, 0.69, 0.37). Leg formula: IV–I–II–III. Dorsal scutum ovoid, smooth, densely covered with short hairs. Booklung covers oval, large. Pedicel tube short, with dorsolateral extension, scuto-pedicel region with paired curved scutal ridges (Fig. 2E, F). Sperm pore narrow, slit-like. Colulus small, bearing two setae. Cymbium and bulbus of palp yellow. Bulbus longer than cymbium, bulged proximo-ventrally, apex conical, acute tipped. Embolusconductor complex, mesially bent in dorsal view (Figs 4A, B).
Female. Similar to male in coloration and general features, but body size larger, sternum without palpal groove. Body length 3.03–3.41; carapace 1.31–1.38 length, 0.96–1.01 width; abdomen 1.48–1.76 length, 1.21–1.31 width. Measurements of legs: I 3.48 (1.08, 0.66, 0.74, 0.66, 0.34); II 3.23 (1.03, 0.57, 0.63, 0.66, 0.34); III 2.76 (0.86, 0.48, 0.51, 0.57, 0.34); IV 3.93 (1.14, 0.66, 0.85, 0.83, 0.45). Epigastric area without any external specialities (Figs 2D, 4C). Vulva with a large receptaculum and complicated sclerites (Fig. 4D).
