Stylogaster souzai Monteiro, 1960: 111 . Type locality: Brazil, Amapá, Mazagão, “do Jari ao Vila Nova”.

This species was previously known only from Amazonian Forest in the states of Amapá and Pará ( Monteiro, 1960; Camras & Parrillo, 1985; Camras & Parrillo, 1996). This provides the first record for northeastern Brazil. The female and egg are herein described for the first time. Males with the same collecting data were identified by comparison with the holotype.

Male. Diagnosis —Pedicel longer than the postpedicel; mid tibia with one white spur; two basal setae on wings; tergite 1 with a series of white and black setae; sternite 5 with sparse setulae and a slight indentation on the posterior margin; phallus with two narrow apical membranous projections.

Female Description. Ocellar triangle pointed, reaching middle of the frons, frons entirely brown; scutum brown with paler longitudinal strips, anepisternum brown; segments VI and VII yellow with dorsal brown spot; sternite 8 brown with yellow lateral spot; fore tibia with one white spur; no spur on mid tibia; no long setae on inferior face of the hind leg; hind tibial spur black; tergite 1 only with white setae on the inferior half; “ovipositor” nearly as long as abdomen; tergites 6 and 7 with setae only on the superior half (Fig. 1); sternite 8 with setulae covering almost all extension (Figs. 2–4), ventral face with one pair of apical reclinate and some differentiated proclinate setae, and a median elevation on its basal half (Fig. 4); cercus narrowed on the base and length not reaching the hypoproct (Fig. 3, ce); lateral lobes of sternite 8 in internal position relative to the lateral sides of syntergostergite, thinner than cerci and reaching half of the hypoproct (Fig. 3, eg); apex of lateral lobes of sternite 8 rounded; apex of “ovipositor” with a characteristic indentation (Fig. 4).

Egg Description. Elongated chorion, one pair of recurrent spines with more than twice the length of the posterior spine; posterior spine curved and naviform (Fig. 5).
