Forewing black with hyaline band at center basal to stigma and hyaline band near apex apical to stigma. Head long behind eyes, shining. Mesosomawith anterolateral lobes of mesonotum roundly produced; mesonotum shining, with large closely set punctures. Hind coxa smooth, shining. Pronotum with 2 anteriorly projecting teeth, dorsal on e small.  Female: Length, 13.0 mm; forewing length 10.0 mm; ovipositor length, 6.0 mm. Color: Antenna black; scape and pedicel orange. Head orange with large black area from just behind ocelli through frons to about level of antenna.; apex of mandible black. Mesosomablack with propleuron and pronotum orange. Legs orange with hind femur and tibia dark brown; tarsi yellowish. Metasoma orange; ovipositor sheath black. Forewing with base, broad band below stigma, and apex black; stigma brownish ( Fig. 81). Hind wing hyaline at base, becoming black toward apex. Veins black, those in hyaline parts yellowish to brown. Head: Antennal length 2.7X head width. Lower interocular distance subequal to eye height; malar space about 0.3X eye height ( Fig. 77). Head from above long behind eyes, straight, length of head 1.2X eye length ( Fig. 78). Occipital carina very narrow, less than a fifth diameter of an ocellus. Smooth and shining, few fine punctures on frons; pubescence densest on fronts to clypeus and malar area, sparse elsewhere ( Figs 77, 78).  Mesosoma: Pronotumwith two anteriorly projecting teeth near dorsum. Propleuron smooth and shining. Mesonotum shining with large punctures, distance between most punctures more than a puncture diameter ( Fig. 80); pronotum with broad smooth and shining diagonal band, coarsely reticulate above and below band; mesopleuron with dorsoanterior finely punctate area, rest coarsely reticulate; metapleuron and propodeum coarsely reticulate ( Fig. 79). Hind coxa smooth and shining, few indistinct carinae laterally, 2.0X longer than broad; ovipositor groove on inner surface indistinct. Hind basitarsus subequal to length of remaining tarsal segments combined. Tarsal claw with 6 teeth and indistinct basal lobe; lower tooth small and near basal lobe ( Fig. 82). Forewing with cells 1M and 1Rs contiguous, without vein Rs+M; costal cell broad, 1.2 times broader than stigma ( Fig. 81). Hind wing with veins distinct, cells Cu and R1+Rs contiguous ( Fig. 81). Metasoma: Shining; fine white pubescence and fine punctures on segments 2 to apex. Ovipositor length about 0.6X forewing length.   Figs 77-82:  Pristaulacus decorus. 77Head, front. 78Head, dorsal. 79 Mesosoma, lateral. 80 Mesosoma, dorsal. 81Wings. 82Tarsal claws.  Male:Length, 13.0 mm; forewing length, 13.0 mm. Color and structure similar to female except: Black on head ends above antennal insertions; propleuron may be black; metasoma may be black at base or almost entirely black.  Types:  Holotype: Female, labeled “ 13 mi. S.
