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 ).
