Wings slightly dusky; forewing with black spot under stigma and at apex; veins and stigma black. Head: Lower interocular distance 1.4X eye height; malar space neatly 0.5X eye height ( Fig. 144). Head from above, sharply narrowing behind eyes, distance behind eyes subequal to eye length ( Fig. 145). Occipital carina broad, flangelike, more than half diameter of an ocellus ( Fig. 145). Shining; gena and vertex with large punctures, mostly separated by flat, shining interspaces 2X or more puncture diameters; frons with closely set punctures, interspaces ridgelike, mostly equal to puncture diameters; with fine white pubescence, densest on lower inner orbits, malar area, and clypeus ( Figs 144, 145).  Mesosoma: Pronotumwithout anteriorly projecting tooth. Propleuron punctate. Mesoscutum with transverse carinae; axillae and sides of mesoscutellum reticulate, center of mesoscutellum with transverse carinae; propleuron shining, punctate; pronotum mostly punctate, punctures finer dorsoposteriorly; mesopleuron finely punctate on upper half, reticulate mixed with punctures on lower half; metapleuron mostly reticulate; propodeum finely punctate to reticulate, shining with few carinae near metasomal insertion ( Figs 146, 147). Hind coxa with transverse carinae. Tarsal claws with 4 teeth. Hind basitarsus slightly longer than remaining tarsal segments combined. Forewing with long vein Rs+M separating cells 1M and 1Rs (as in Fig. 157). Hind wing veins distinct, cells Cu and R1+Rs contiguous (as in Fig. 110). Metasoma: Smooth, shining, with fine white pubescence on segments 4 to apex. Ovipositor length about 1.5X forewing length.  Male:Unknown.    Holotype:Female is at OSU, labeled “Chiricahua M., Ar, VII-26-87,” “D.J. & J.N. Knull Collrs,” “ Holotype” [red], “ Pristaulacus arizonicus Tow.type” [TOWNES’ name label].  Specimens examined:  UNITED STATES. ARIZONA: Cochise Co., Cave Cr.
