Etymology.

The specific epithet is a noun in apposition taken from the Tsafi´ki languange, meaning 'red devil’.

Diagnosis.

Males are distinguished from all species by their very long dorsal, basally pointing embolic process (Fig. 10). Females are distinguished by their X-shaped anterior genitalic process of the internal genitalia (Fig. 12), from S. tandapi Platnick & Dupérré, 2011 by the more centrally positioned apodemic projections (Fig. 12); more externally positioned in the later species (Platnick and Dupérré 2011; figs 222, 223).

Description.

Male (holotype). Total length: 2.3; carapace length: 1.4; carapace width: 1.1.

COLORATION: Carapace and sternum reddish (Figs 31, 32); mouthparts orange-brown; abdominal scuta reddish, abdominal soft portions white; legs red-orange (Figs 31, 32).

CARAPACE: Carapace broadly oval; covered with low tubercles; fovea absent (Fig. 32). Clypeus margin rebordered, elongated median projection present (Fig. 9). Sternum wider than long, not fused to carapace, surface highly crenulated. Chelicerae slightly divergent, anterior face with swelling; with one promarginal tooth and dorsally directed spine (Figs 9, 31). Labium triangular, not fused to sternum, anterior margin indented at middle. Endites distally excavated, with a short ventral, and a longer dorsal processes. EYES: Six, well developed; ALE largest, oval, PME squared, PLE oval; posterior eye row straight in dorsal view; ALE separated by their radius, ALE-PLE touching, PME touching, PLE-PME touching. LEG: Leg formula: 4123; leg spination: Tibiae I v2-2-2-2-2; metatarsi I v2-2-2; tibiae II v2-2-2-2-2; metatarsi II v2-2-2. ABDOMEN: Ovoid; book lung covers large, ovoid; posterior spiracles not connected by groove; dorsal scutum present, strongly sclerotized, not fused to epigastric scutum, entirely smooth; epigastric scutum strongly sclerotized, surrounding pedicel, not protruding; postepigastric scutum strongly sclerotized, almost semicircular, fused to epigastric scutum; spinneret scutum absent, supraanal scutum absent. GENITALIA: Cymbium yellow; bulb yellow, oval, rounded apically; embolus large, small point apically, with large angular basal projection and dorsal, basally pointing projection (Fig. 10).

Female. Total length: 2.9; carapace length: 1.3; carapace width: 1.1.

COLORATION: As in male, except abdomen withish (Fig. 33). CARAPACE: As in male. Clypeus margin rebordered, with small median projection. Sternum as in male. Chelicerae not divergent, without swelling; with one promarginal tooth. Labium triangular, not fused to sternum, anterior margin deeply indented medially. Endites not excavated. EYES: As in male. LEG: As in male. Female palpal claw absent. ABDOMEN: Ovoid; book lung covers large, ovoid; posterior spiracles not connected by groove; dorsal scutum absent (Fig. 33); postepigastric scutum strongly sclerotized, almost semicircular, fused to epigastric scutum; spinneret scutum absent, supraanal scutum absent. GENITALIA: Atrium trianglular; epigastric scutum with see through X-shaped mark (Fig. 11); epigastric scutum with an X-shaped marking (internal genitalia visible by transparence); apodemes long with internally positioned small, triangular projections (Fig. 12).
