Diagnosis. The female of Berlandiella zabele sp. nov. is similar to B. magna and B. querencia by the long and ellipsoid spermathecae ( Figs 4–7), but are distinguished from those species by having its copulation opening more widely separated from each other and located on the posterior edge of the epigynal groove ( Figs 4, 6). The male resembles B. querencia in possessing a cymbial process (CP), but differs by the position of the CP, closest to the cymbium ( Figs 8–10, 13, 15, 16), by the long retrolateral tibial apophysis (RTA), excavated in the distal portion ( Figs 8–11, 15, 16).

Description. Female (holotype – MPEG.ARA 34482). Carapace slightly longer than wide, wider at the level of legs III, narrowed anteriorly, with many sockets of bristles; median region yellow with a brown central spot and wide dark brown bands on each side, formed by a tangle of dark spots. Clypeus vertical with many sockets of bristles, with a median brown spot and irregular spots on lateral. Chelicerae yellow with two teeth on the promargin of the fang furrow, with a large dark brown spot on the anterior face. Labium orange with rounded apex, reaching almost to the middle of the endites. Endites pale yellow, excavated diagonally. Sternum pale yellow. Legs covered by various types of setae and with many robust macrosetae on tibiae and metatarsi.

Long and thin trichobothria in tarsi and metatarsi, with distal and proximal plate limit well differentiated; the distal margin of the trichobothrial hood is well defined; hood entire, differentiated with transverse ridges; alveolus notched; distal plate smooth, slightly elevated. Femura yellow with brown spots, more abundant in prolateral sides of femora I-III, and a small white spot at the apex; patellae I-III yellow with brown spots; patella IV yellow; tibiae and metatarsi I-III yellow, shaded with brown, but tibia and metatarsus III darker; tibia IV yellow with a basal dark spot on prolateral side; tarsi I-IV yellow, with a dark ring at their bases. Tarsal claw pectinate and conspicuous with claw apex tooth curved and seven short and robust teeth. Palp yellow with brown spots. Abdomen yellow, longer than wide, densely covered by setae sockets, the dorsum covered by a wide brown spot with two longitudinal yellow bands around the heart mark; laterals yellow shaded with brown and the venter yellow stippled with brown.

Distribution. Known only from the type locality ( Fig. 44).

Etymology. The specific epithet refers to a mythological character known by indigenous people of Piauí. According to indigenous mythology, Zabelê, a member of the Amanajós tribe, fell in love with Metara, a member of an enemy tribe. When the romance of Zabelê and Metara was discovered, tribal warfare result- ed in the death of both lovers. The god Tupã pitied the two lovers and so transformed them into birds that fly together for eternity.

Remarks. The general color, legs especially, vary in the abundance of brown spots and some specimens may be darker or lighter than the paratype. The pattern of ventral macrosetae of the legs also varies between individuals.
