Diagnosis: This species is similar to G. insularis Simon, 1907, but can be distinguished by the strongly elevated carapace (Fig. 1H), the very small booklung covers, the absences of dorsolateral extension in pedicel tube and couple of strong teeth on scutal ridge of scuto-pedicel region (Fig. 2I).
Description: Male. Body reddish brown except chelicerae and sternum lighter, legs yellow. Body length 2.28–2.54; carapace 1.01–1.07 length, 0.83–0.86 width; abdomen 1.40–1.60 length, 0.94–1.24 width. Clypeus with a row of strong hairs at anterior margin; clypeus height about 0.5 times the diameter of anterior eyes. Pars cephalica strongly elevated in profile (Fig. 1H). Carapace strongly granulated at two sides and smooth on top, with a row of finely hairs along margin, its dorsal surface with irregularly two rows of short, finely hairs laterally and several directed, adpressed hairs medially (Fig. 1G). Eyes six, ALE slightly larger, PLE and PME nearly equal sized; ALE separated by less than its diameter; posterior eye row nearly straight in dorsal view. Labium with 2 setae at anterior margin. Sternum with narrow, transverse palpal groove, covered with thin hairs standing in relatively large pits, radial furrows well discernible (Fig. 1I). Measurements of legs: I 2.41 (0.74, 0.37, 0.54, 0.48, 0.28); II 2.33 (0.71, 0.37, 0.51, 0.46, 0.28); III 2.03 (0.63, 0.34, 0.40, 0.43, 0.23); IV 2.71 (0.83, 0.43, 0.60, 0.57, 0.28). Leg formula: IV–I–II–III. Dorsal scutum ovoid, punctate, densely covered with short hairs. Booklung covers very small, oval, anterolateral edge with tubercle. Pedicel tube short, without dorsolateral extension, scuto-pedicel region with straight scutal ridge and conspicuous ventral-arched anterior scutal ridge (Figs 2H, I). Sperm pore narrow, slit-like. Colulus very small, bearing two setae. Cymbium and bulbus of palp yellowish, other segments yellow. Bulbus slightly longer than cymbium, apex conical, blunt tipped. Embolus-conductor complex, mesially bent in dorsal view (Figs 5A, B).
Female. Similar to male in coloration and general features, but body size larger, sternum without palpal groove. Body length 2.71–2.97; carapace 1.02–1.14 length, 0.94–0.98 width; abdomen 1.68–1.86 length, 1.37–1.54 width. Measurements of legs: I 2.32 (0.69, 0.40, 0.51, 0.46, 0.26); II 2.27 (0.71, 0.37, 0.48, 0.45, 0.26); III 1.94 (0.63, 0.34, 0.37, 0.40, 0.20); IV 2.61 (0.81, 0.46, 0.57, 0.51, 0.26). Epigastric area without any external specialities (Figs 2G, 5C). Vulva with a large receptaculum and complicated sclerites (Fig. 5D).
