Diagnosis. Female flagellum with a 2-segmented clava (Figs 78, 96); antennal scrobes as narrow grooves (Fig. 13); frontal suture absent (Fig. 13); occipital margin sharp with posterior ocelli situated away from margin (Fig. 29); midlobe of mesoscutum with 2 pairs of setae (Fig. 43); scutellum with 1 pair of setae (Fig. 43); forewing with submarginal vein with 2 setae.

Description. FEMALE. Length 1.8−2.1 mm.

Scape yellowish-brown, pedicel and flagellum dark brown. Frons, vertex, mesoscutum and scutellum black with metallic bluish-green tinges. Coxae, femora and tibiae dark and metallic, fore tarsus dark brown, mid and hind tarsi with tarsomeres 1–3 yellowish-brown and 4 dark brown. Forewing with median 1/3 weakly infuscate.

Flagellum with 2 small discoid anelli, 3 funiculars and a 2-segmented clava (Figs 78, 96). Frons and vertex with strong, raised reticulation. Antennal scrobes as narrow grooves. Frontal suture missing. Occipital margin with a sharp edge. Eyes bare.

Mesoscutum 0.5X as long as wide; with strong, raised reticulation; midlobe with 2 pairs of setae; notauli indistinct. Scutellum 1.0X as long as wide; with strong, raised reticulation; with 1 pair of setae. Propodeum predominantly reticulate, with anterior 1/3 of median part smooth; propodeal callus with 3 setae; with a complete median carina, narrow anteriorly and gradually widening towards posterior part, carina is concave. Forewing with 2 setae on dorsal surface of submarginal vein; costal cell bare; speculum large, open below.

Petiole not visible, but presumably short. Gaster ovate; gastral tergites strongly reticulate.

Ratios. HE/MS/WM = 3.1/1.0/2.3; POL/OOL/POO = 3.2/1.8/1.0; WH/WT = 1.2; LW/LM/HW = 1.9/1.0/ 1.1; PM/ST = 1.0; MM/LG = 0.7–0.9.

MALE. Unknown.

Material examined. Holotype female “ BRAZIL, Sao Paulo, Araraquara, COHAB Vitorio DeSanti, Vegetacao de Cerradao, ex galha peciolar Liana, 13.vii.1997, M.T. Tavares”, in MZSP. Paratypes: 9 females with same data as holotype (5 females in MZSP; 4 females in BMNH).

Etymology. Named for the strongly sclerotized and stout body (Greek pegos = strong, solid; soma = body).
