Etymology.

The specific epithet is a noun in apposition taken from the Tsafi´ki languange, meaning ‘orange’.

Diagnosis.

Males are distinguished from all species by the short, strongly curved embolus and the small waved prolateral extension of the conductor (Fig. 22); from B. baobab Bolzern, 2014 by the large and rounded retrolateral process of the conductor (Fig. 22) which is absent in the latter ( Bolzern 2014, fig. 511).

Description.

Male (holotype). Total length: 1.5; carapace length: 0.7; carapace width: 0.6.

COLORATION: Carapace orange-brown with darkened spot on posterior half of carapace (Fig. 35); sternum, mouthparts pale orange-brown; dorsal abdominal scutum orange; legs orange; abdomen soft portion withish with indistinct netlike pattern (Fig. 35). CEPHALOTHORAX: Broadly oval in dorsal view (Fig. 35), pars cephalica slightly elevated in lateral view; surface of elevated portion and sides of pars cephalica finely reticulate; fovea absent. Clypeus margin unmodified, straight in frontal view, vertical in lateral view. Sternum as wide as long, not fused to carapace, surface smooth. Labium rectangular, fused to sternum, not indented at middle. Endites with anteromedian projection with 5-6 setae. Chelicerae slightly divergent; cheliceral teeth not observed. EYES: Six eyes, well developed, all subequal, ALE oval, PME squared, PLE oval; posterior eye row straight from above; ALE touching, ALE-PLE touching, PME touching throughout most of their length, PLE-PME touching. ABDOMEN: Oval; book lung covers large, ovoid; only anterior spiracles connected by groove. Dorsal scutum present, strongly sclerotized, without color pattern, covering more than of abdomen length and most of abdomen width, anteriorly fused to epigastric scutum, middle surface, sides smooth (Fig. 35). Epigastric scutum strongly sclerotized, surrounding pedicel entirely. Postepigastric scutum strongly sclerotized covering to nearly full abdomen length, almost semicircular, completely fused to epigastric scutum. Spinneret scutum present, supraanal scutum absent. LEGS: Leg formula 4123; leg spination: Femur I p0-1-1, tibia I v2-2-2-2, metatarsus I v2-2-2; femur II p0-0-1, tibia II v2-2-2-2, metatarsus II v2-2-2. GENITALIA: Male palp not strongly sclerotized (Fig. 22). Cymbium not fused with the bulb (Fig. 22). Embolus basally broad, flattened dorsoventrally, distally narrowing, tip bent prolaterally; conductor situated ventroprolaterally, dividing into a small wave like process prolaterally and a large rounded process retrolaterally (Figs 22, 23).

Female. Unknown.
