Description. Male. Head. Ocellar setae stronger than postoculars. Outer vertical seta of same size as postoculars. Black orbital setae. Three frontal setae situated below the dorsal limit of the lunule. All genal setae black. First two rows of occipital setae black, others yellow. Thorax. Chaetotaxy: acrostichals = 0 + 1, dorsocentrals = 0 + 3 (anterior one shorter), intra-alars = 2 + 2 (anterior one shorter), supra-alars = 2 + 3, basal scutellars = 4. Prosternum and posterior surface of hind coxa with black setae. Black antero-ventral scutellar setae. Three katepisternal setae. Postalar wall with only black setae. Lower calypter with a central dark spot and a fringe of long hair-like setae along outer margin, extending to or almost to its posterior margin. Mid femur with a ctenidium. Antero-dorsal surface of mid tibia with 1 median and 1 apical seta. Hind femur with a row of antero-ventral and a row of posteroventral setae. Hind tibia antero-dorsally with 1 seta in the basal third, 1 in the middle third and 1 preapical.

Abdomen. Postero-ventral seams between T3/T4 and T4/T5 parallel. Posterior seam of T5 not projected posteriorly and ventrally, and normal setae in postero-ventral area directed posteriorly. T5 with golden microtrichosity. Microtrichosity of the abdomen laterally golden. ST1+3 with only black hair-like setae. Four lateral setae on each side of T4. Terminalia. ST5 brown. Medial margin of ST5 ∩-shaped. Inner margins of ST5 arms straight, with long hair-like setae posteriorly. Syntergosternite 7+8 longer than high in lateral view, brown anteriorly and yellow posteriorly with golden microtrichosity. Epandrium bright orange. Cercus orange proximally and brown or dark brown distally. Cercus in lateral view progressively narrowing towards the apex, with the distal half slightly curved. Cercus with short, dorsal spines. Cercus with 4 long and strong ventral spines, all of them directed forward. Cercal apex acute in lateral view. Surstylus brown, finger-shaped with anterior margin slightly projected towards the anterior body region, with an acute apex. Postero-distal surface of surstylus as sclerotized as the rest of surstylus. Pregonite tongue-shaped, curved in lateral view, with a lateral projection, and an undulated apex. Postgonite elongated, with a hooked apex. Basi- and distiphallus connected by a desclerotized strip. Juxta with juxtal lateral plate with three juxtal horns. Basal horn is longer than the others. The bifurcation giving origin to the juxtal lateral plates is superficial at the juxtal apex and leaves the lateral plates close to each other. Juxta short, almost as long as the vesica in lateral view. Distiphallus with a pair of lateral styli separated, each with a longitudinal cleft. Short vesica composed of one entire plate without demarcated connection with the distiphallus.

Variable features. Ocellar setae of same size as postoculars. Chaetotaxy: dorsocentrals = 0 + 4 (anterior two shorter), intra-alars = 1 + 2 (anterior one shorter), supra-alars = 1 + 4. Hind tibia antero-dorsally with 2 setae in the basal third, 1 in the middle third and 1 preapical. Two lateral setae on each side of T4.

Distribution. NEOTROPICAL— Argentina (Misiones, San Luis), Brazil (Mato Grosso, Río de Janeiro, Río Grande do Sul, Santa Catarina, São Paulo), Paraguay (Paraguarí).
