Etymology.

The specific epithet is a noun in apposition taken from the Tsafi´ki languange, meaning "fish hook" for the shape of the dorsal apophysis of the male palp.

Diagnosis.

Males and females are similar to R. hedlite and R. tandapi by the presence of two large, reflective eyes. Males are distinguished from R. tina Platnick & Berniker, 2011 by their double hook-shaped dorsal apophysis (dap2), simple in the latter species (Platnick and Berniker 2011; fig 392); from R. tandapi Platnick & Berniker, 2011 by the spine-like dorsal apophysis (dap1), bidentate in the later (Platnick and Berniker 2011; fig 367). Females are distinguished by their elongated oval, truncated apically anterior genitalic process (Fig. 21); sinuous and subdistally narrowed in R. tina Platnick & Berniker, 2011.

Description.

Male (holotype). Total length: 0.9; carapace length: 0.5; carapace width: 0.3.

COLORATION: Carapace, sternum, mouthparts beige, without pattern; abdomen beige, without pattern; legs pale beige (Fig. 34). CARAPACE: Piriform in dorsal view (Fig. 34); elevated portion of pars cephalica finely reticulate, sides finely reticulate. Fovea absent, lateral margin undulate. Clypeus margin strongly rebordered, sinuous in front view, sloping forward in lateral view. Sternum longer than wide, surface smooth, radial furrows between coxae I–II, II–III, III–IV smooth, with an additional radial between endites and coxae I. Chelicerae straight, cheliceral teeth not observed. Labium triangular, not fused to sternum, anterior margin slightly incised at middle. Endites elongated, triangular tip. EYES: Two large, reflective eyes, separated by half their radius (Fig. 34). ABDOMEN: Cylindrical (Fig. 34). Booklung covers large, ovoid. Dorsal scutum absent. Epigastric scutum weakly sclerotized, not surrounding pedicel. Postepigastric scutum weakly sclerotized, yellow, short, only around epigastric furrow, not fused to epigastric scutum. Spinneret scutum, supraanal scutum both absent. LEGS: Leg formula 4123; spineless. GENITALIA: Male palp not strongly sclerotized (Fig. 18); cymbium ovoid in dorsal view, cup-shaped; bulb longer than the sclerotized cymbium (Fig. 18); embolus flagellum-like, basally sinuous, accompanied dorsally by conductor (c), ventrally by a wide, apically pointed ventral apophysis (vap), dorsally with two apophysis, one spine-like (dap1) and one double hook-shaped (dap2) (Figs 18, 19).

Female. Total length: 1.1; carapace length: 0.6; carapace width: 0.3.

COLORATION: As in male. CARAPACE, EYES and ABDOMEN: As in male.

LEGS: As in male; female palp without claw. GENITALIA: Anterior genitalic process somewhat visible through the epigastric scutum, epigastric scutum margin with a wide trapezoid sclerotized area medially (Fig. 20); anterior genitalic process elongated oval, truncated apically, process set in wide wing-like structure (Fig. 21).
