( Figs 50–55 , 106, 110, 115, 121 )

Holotype. BRAZIL: Parque Nacional do Caparaó—Posto Santa Maria, Ibitirama , Espírito Santo, 10–14/iii/2006 (R. Kawada) ( UFES) . Paratype, BRAZIL: 1♂, Ribeirão Grande , São Paulo, 21/i/2011 (N.W. Perioto) ( DZSJRP) .

Male description. Structure: Mesopleural transverse sulcus thin and well-marked, broadening towards the dorsal margin of the mesopleuron. Forewings hyaline, ferruginous on the anterior margins and stigma. The marginal cell castaneus; epipygium with deep and well-marked punctures, feebly stretched sublateraly and the subapical surface centrally smooth; first metasomal sternite without tuft of hairs; hypopygium subquadrate, the apical margin with apico-lateral extensions up-folded, forming a rounded notch centrally.

Genital capsule: Basal ring long, with its dorsal surface longer on its apical margin. With a longitudinal line medially in dorsal view; gonocoxite tapering towards the apex in lateral view, with about 3/4 the gonostylus extension. Strongly depressed basally, with concave ventral margin. The apex thin and rounded, slightly separated; aedeagus feebly lamellate, as long as the gonostylus, with a rounded lobe apically; gonostylus slender, feebly tapering towards the rounded apex. With golden pubescence on the half apical region margins.

Coloration. Body black with several yellow markings. Clypeus except for the basal and apical margins. Mandibles with dark margins and teeth. Supra-antennal plates, except for a minimum line between them. Internal surface of the scape and tip of the apical flagelomere. Yellow or ferruginous tyloids on the flagelomeres VI–XI. Bands contouring the frontal margin of the eyes, from the clypeus margin to the posterior ocelli. And the genal margin of the eyes narrowing towards the vertex. With or without a pair of spots on the vertex. The anterior margin of the neck. The anterior margin of the pronotum, interrupted dorsally and stretching to the lateral margin, where is broadened and almost fused to the fasciae of the posterior margin. Prosternum with or without diffuse spots. Tegulae yellow. Mesepisternal lamellae yellow or not. A pair of triangular spots on the mesoscutum surface and oval spots on the scutellum. Lateral spots reaching from the mesoscutum to the scutellum anterior margin. The metanotum except for the fossae. The metapleuron almost completely yellow. Propodeum with a pair of large spots ‘u’ shaped and a small one before the petiolar socket. Mesopleuron except for the transverse sulcus and margins. Legs except for the castaneus hindtibia and hindtarsi, trochanter, base of the femora and brown tarsal claw. The lateral of the tergite I, stretching and converging on a submarginal transverse posterior fasciae. Trasversal fasciae before the apex of tergite I–IV, broader on the lateral surface, sometimes broadly interrupted. Sternite I almost entirely or diffusely yellow. Broad transverse fasciae on the sternite II–IV almost or broadly interrupted.

Female: unknown.

Etymology. From Latin, margines —“margins”; and plicata —“folded”. Referring to the apico-lateral margins of the hypopygium, which are folded up in the posterior view.

Distribution. Recorded from the Atlantic Forest of the southeastern Brazil.

Discussion. None of the three individuals analysed had the tuft of hairs on the first metasomal sternite.
