Guadana arawak sp. n. Figs 17−19, 22−23, 26−28, 58, 68 Type material: Holotype: ♂ from FRENCH GUIANA: Regina Commune: Nouragues National Reserve (Research Station) (4.0833, -52.6667), 5 May 2010, V. Vedel leg. (MNHN). 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) and dRTA barely reaching the proximal margin of the alveolus (Figs 2, 18). They are distinguished from those of the latter species by the basal projection with jagged margin (smooth in the other species) (Figs 18, 68). 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). 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, 26−28, 58, 68). Female: unknown. Distribution. Only known from the type locality in the French Guiana (Fig. 81).
