DCBU 419919, Paratype: female, Luis Antonio, SP, Brasil ESEC de Jatai S 21º36´54” W 47º47´02” Armadilha Malaise 09. V.2007 A.M.Penteado-Dias col. DCBU 419920.
Diagnosis. This new species of Procestus, can be recognized by the following combination of characters: epomia ending dorsally below upper edge of pronotum; posterior transverse carina absent; frons simple; metasoma mostly yellow; metapleuron mostly yellow; apical part of fore wing with a blackish spot.
Description. Female (Fig. 1): Fore wing length 7.6 mm; hind wing length 5.2 mm.
Head. Malar space about 0.7 × as long as basal mandibular width (Figs 4 & 5); frons simple (Figs 2, 3 & 5), ocelli median, the posterior one separated from the orbit by about 0.8 × its own maximum diameter (Figs 2 & 5); gena flat behind eye; occipital carina not broadened into a flange (Fig. 1); antenna slender, with 41 flagellomeres.
Mesosoma. Epomia (Figs 4 & 5) ending dorsally below upper edge of pronotum; mesoscutum with fine setiferous punctures over most of its surface (Figs 4 & 5); mesopleuron with sparse setiferous punctures anteriorly (Fig. 4); metapleuron from the middle to the upper margin with sparse setiferous punctures (Fig. 4); pleural carina complete (Fig. 4); propodeum without posterior transverse carina (Figs 9 & 10); fore tarsal claws with slender, pale-colored pecten teeth on their basal 0.7; mid tibia with 27 small denticles on outer surface (Fig. 8); fore wing with bulla in 2m-cu vein 0.8 as long as the rest of this vein (Figs 1 & 11); hind wing with nervellus (composite vein first abscissa of CU&cu-a) intercepted at its center (Fig. 12).
Metasoma. Metasoma with tergite I very slender (Fig. 1), about 3.9 × as long as posteriorly broad; ovipositor projecting beyond apex of metasoma by about 2.4 × the length of the hind tibia (Fig. 1).
Coloration (Fig. 1). Head yellow with apex of mandibles brownish; central part of vertex and occiput black; antenna brown, with scape, pedicel, flagellomeres I–III yellow. Mesoscutum yellow with three longitudinal strips and a posterior blackish spot; mesopleuron yellow with two ventral blackish spots and a central brownish spot; metanotum with transverse dark brown strips, propodeum with lateral dark brown spots; fore legs yellow; mid legs yellow with tarsi dark orange; tarsomere 5 brownish; hind legs mostly orange. Metasoma tergite I–III mostly (anteriorly and posteriorly) yellow, the rest orange; tergite IV–VII orange; wings infumate with an apical brownish spot; pterostigma light brown.
Variation. Paratype: Fore wing length 6.8 mm; hind wing length 4.7 mm. Malar space about 0.5 × as long as basal mandibular width; posterior ocelli separated from the orbit by about 0.7 × its own maximum diameter. Fore tarsal claws with slender pale-colored pecten teeth on their basal 0.6; mid tibia with 21 small denticles on outer surface; fore wing with bulla in 2m-cu vein 0.6 as long as the rest of this vein. Metasoma with tergite I very slender (Fig. 13), about 3.1 × as long as posteriorly broad; ovipositor projecting beyond apex of metasoma by about 2.2 × the length of the hind tibia (Fig. 13).
Coloration (Fig. 13). Mesosoma, specially mesopleuron and propodeum most extensively black marked.
Etymology: The name refers to the type locality (i.e. The Jataí Ecological Station).
