Etymology. The specific name refers to the Arawak Indians, the first people known to inhabit French Guiana; noun in apposition.

Diagnosis. Males of G. arawak sp. n. resemble those of G. alpahuayo sp. n. by the palps with embolus bearing a subdistal keel at tip ( Figs. 67−68 View FIGURES 67−76 ) and dRTA barely reaching the proximal margin of the alveolus ( Figs 2 View FIGURES 1−5 , 18 View FIGURES 15−19 ). They are distinguished from those of the latter species by the basal projection with jagged margin (smooth in the other species) ( Figs 18 View FIGURES 15−19 , 68 View FIGURES 67−76 ). Females are unknown.

Description. Male (holotype): prosoma pale brownish orange; cephalic region with three longitudinal, pale brown stripes running from posterior eyes to fovea; thoracic region with pale brown marks laterally; fovea and thoracic striae brown; eye borders black; clypeus pale yellow with dark brown antero-lateral margins. Chelicerae pale yellow with rounded brown proximal marks. Legs and palps pale brownish yellow with brown spots at the base of spines. Labium and endites pale brownish-orange at base, distally pale yellow. Sternum pale yellowish cream colored with brown margins. Opisthosoma pale yellow with no distinctive pattern; dorsally with two large, oval muscle impressions; ventrally with pair of curved lines of muscle impressions ( Figs 22−23 View FIGURES 20−23 ). Total length 6.1. Prosoma: 2.8 long, 2.8 wide. Opisthosoma: 3.1 long, 2.3 wide. Eyes: diameters: 0.18, 0.20, 0.16, 0.22; interdistances: 0.10, 0.02, 0.26, 0.22, 0.20, 0.18. Legs (2143): I: 19.8 (5.2, 1.5, 5.8, 5.3, 2.0); II: 21.4 (5.6, 1.5, 6.3, 6.0, 2.0); III: 14.1 (3.9, 1.1, 3.9, 3.9, 1.3); IV: 16.4 (4.3, 1.1, 4.4, 4.9, 1.7). Palp: vRTA triangular, similar in size to dRTA; dRTA distally bifid, with one branch tappering and the other laminar; DTA sinuous in ventral view, subdistally curved retrolaterally; conductor hyaline, same width throughout the entire length; embolus strongly curved prolaterally ( Figs 17−19 View FIGURES 15−19 , 26−28 View FIGURES 24−28 , 58 View FIGURES 57−66 , 68 View FIGURES 67−76 ).

Female: unknown.

Distribution. Only known from the type locality in the French Guiana ( Fig. 81 View FIGURES 81−82 ).
