Description. Male. Head. Ocellar setae stronger than postoculars. Outer vertical seta stronger than postoculars. Black orbital setae. Four 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. Three katepisternal setae. Postalar wall with only black setae. Lower calypter white, with a fringe of long hair-like setae along outer margin, extending almost to its posterior margin. Mid femur with a ctenidium. Antero-dorsal surface of mid tibia with 2 medial setae and 1 apical seta. Hind femur with a row of antero-ventral and a row of postero-ventral 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. Microtrichosity of the abdomen laterally golden and grey. ST1+3 with only black hair-like setae. Two lateral setae on each side of T4. T5 with golden microtrichosity. Terminalia. ST5 orange. Medial margin of ST5 ∏- shaped. Inner margins of ST5 arms straight, with a patch of short setae medially and long hair-like setae posteriorly. Syntergosternite 7+8 longer than high in lateral view, orange, 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 setae on dorsal surface distributed apically. Dorsal margin of cercus strongly angled, cercal apex acute and slightly elongated in lateral view. Cercal prongs with a straight apex in dorsal view. Surstylus orange, finger-shaped with anterior margin slightly projected towards the anterior body region, with a rounded apex. Postero-distal surface of surstylus as sclerotized as the rest of surstylus. Pregonite tongue-shaped, curved in lateral view, with a lateral projection, an apical incision, and an undulated apex. Postgonite elongated, with a hooked apex. Basi- and distiphallus connected by a desclerotized strip. Juxta without demarcated connection with the phallic tube. Juxta sclerotized and composed of one long plate without juxtal lateral plate and juxtal horns. Juxta with the lateral edges folded ventrally, resembling a tube narrowed towards the straight apex. 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. Lower calypter with central dark spot.

Distribution. NEOTROPICAL— Argentina (Misiones), Brazil (Mato Grosso, Río Grande do Sul, Santa Catarina, São Paulo), Peru (Junin), Paraguay.
