Pristaulacus anteala SMITH , new species

( Figs 93-97 )

Diagnosis:

Head orange with frons between eyes black; antenna black. Mesosoma with mesoscutum and anterior portion of pronotum orange. Forewing with anterior half black, posterior half nearly clear hyaline. Head shining, frons finely punctate. Mesoscutum with transverse carinae. Hind coxa with punctures and cross striations. Pronotum without anteriorly projecting tooth.

Female:

Length, 14.0 mm; forewing length, 12.0 mm; ovipositor length, 7.5 mm. Color: Antenna black; scape orange. Head orange with large black area on frons, extending from hind ocelli to above antenna with extension through interantennal area to clypeus, with inner orbits narrowly orange; apex of mandible black. Mesosoma black; Propleuron orange ventrally; band on posterior margin of pronotum and laterally on anterior margin, and tegula orange. Legs with coxae and most of trochanters black; basal part of mid- and most of hind femora black except apex of hind femur; tibiae and tarsi yellow orange. Metasoma black with narrow posterior margins of segments and base of first segment orange. Ovipositor sheath yellowish with apex black. Forewing with anterior half black, posterior half hyaline ( Fig. 97 ); costa, stigma, and vein 2r of forewing dark orange, remaining veins black; hind wing hyaline to slightly yellowish; veins and stigma brown. Head: Antennal length 2.2X head width. Lower interocular distance subequal to eye height; malar space 0.3X eye height ( Fig. 93 ). Occipital carina very narrow, less than a fifth diameter of an ocellus. Shining, with fine white pubescence; vertex and gena with fine punctures ( Fig. 94 ); frons more densely punctate than vertex with close punctures, interspaces ridgelike and much shorter than puncture diameters; interantennal area and clypeus finely punctate ( Fig. 93 ). Mesosoma: Pronotum without anteriorly projecting tooth. Mesoscutal middle lobe with transverse carinae; mesoscutal lateral lobes, axillae, and mesoscutellum more reticulate ( Fig. 96 ). Propleuron shining; pleura and propodeum finely reticulate, dosoanterior area of mesopleuron finely punctate ( Fig. 95 ). Hind coxa densely punctured with distinct transverse carinae; about 2.1X longer than broad. Tarsal claws with 5 teeth and small basal lobe. Hind basitarsus 1.4X longer than length of remaining tarsal segments combined. Forewing with cells 1M and 1Rs contiguous not separated by vein Rs+M ( Fig. 97 ). Hind wing with veins distinct, cells Cu and R1+Rs separated by vein M ( Fig. 97 ). Metasoma: Shining; fine white pubescence on segment 2 to apex. Ovipositor length about 0.7X forewing length.

Male: Unknown.
