Etymology.

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

Diagnosis.

Males are distinguished by the large rectangular prolateral process of the conductor (Fig. 24), small and rounded in B. pucuna ( Bolzern 2014, fig. 443), leaf-shaped in B. tsachila ( Bolzern 2014, fig. 499), and small and triangular in B. baobab ( Bolzern 2014, fig. 5111). Females are distinguished from B. baobab by the narrow stalk of the anterior genitalic process (Fig. 26), broadly stalked in the latter species ( Bolzern 2014, fig. 519); from B. pucuna , by the small bipartite duct-like structure (Fig. 27), indistinct and bent dorsally in B. pucuna ( Bolzern 2014, fig. 489).

Description.

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

COLORATION: Carapace pale orange-brown with darkened spot on posterior half of carapace; sternum, mouthparts pale orange-brown; dorsal abdominal scutum pale orange-brown; legs pale orange; abdomen soft portion withish with indistinct wide netlike. CEPHALOTHORAX: Broadly oval in dorsal view, 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 anterior part 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 separated by their radius, ALE-PLE touching, PME touching throughout most of their length, PLE-PME touching. ABDOMEN: Ovoid; 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. 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, reduced to two elongated platelets, 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. 24). Cymbium not fused with the bulb (Fig. 24). Embolus basally broad, flattened dorsoventrally, distally narrowing, tip bent prolaterally; conductor situated ventroprolaterally, dividing into a large rectangular process prolaterally (Figs 24, 25).

Female. COLORATION: Overall as in male, except abdomen dorsally and ventrally with indistinct netlike pattern. CEPHALOTHORAX and EYES: overall as in male. ABDOMEN: Oval; book lung covers large, ovoid; epigastric and postepigastric scuta weakly sclerotized, not fused together. LEGS: As in male. Female palp without claw. GENITALIA: Epigynum, anterior genitalic process visible through the scutum (Fig. 26). Internal genitalia with anterior genitalic process narrowly stalked, apex enlarged; posterior genitalic process large, well sclerotized; small forked duct-like structure posteriorly (Fig. 27).
