Forewing with black spot below stigma and black spot at apex. Head shining. Mesoscutum with transverse carinae. Hind coxa smooth, shining. Anterior margin of pronotum with anteriorly projecting tooth.  Female:Unknown.  Male: Length, 7.5 mm; forewing length, 5.0 mm. Color: Black with antennal scape (antenna missing beyond segment 8), spot on posterior margin of vertex, first metasomal segment, and legs beyond trochanters dark orange; hind femur, hind tibia, and hind tarsus brownish to black. Wings hyaline; forewing with black spot under stigma and black spot at apex; veins and stigma black. Head: Lower interocular distance subequal to eye height; malar space about 0.3X eye height ( Fig. 136). From above, roundly narrowing behind eyes, about 0.7X eye length ( Fig. 137). Occipital carina broad, nearly half diameter of an ocellus. Shining with fine white pubescence, pubescence densest on lower frons, lower inner orbits and malar area; vertex with very widely scattered punctures, much farther apart than puncture diameters; frons with punctures, those at center close together, otherwise similar to vertex ( Figs 136, 137).  Mesosoma: Pronotumwith anteriorly projecting tooth. Propleuron shining, without sculpture. Mesoscutal middle lobe with somewhat transverse carinae, rest of mesonotum reticulate. Pleura mostly reticulate with ventroanterior portion of pronotum and upper portion of mesopleuron finely punctate and posterior margin of mesopleuron somewhat scrobiculate ( Figs 138, 139). Hind coxa about 3X longer than broad, shining, with very fine transverse carinae, especially evident on sides. Tarsal claws with 4 teeth, basal tooth very small, possibly representing small acute basal lobe. Hind basitarsus 1.2X length of remaining tarsal segments combined. Forewing with cells 1M and 1Rs separated by very short vein Rs+M (as in Fig. 91). Hind wing veins faint to absent (as in Fig. 157). Metasoma: Segment 2 to apex with fine pubescence and finely punctate.   Figs 136-139:  Pristaulacus omninoniger. 136Head, front. 137Head, dorsal. 138 Mesosoma, lateral. 139 Mesosoma, dorsal.  Types:  Holotype: Male, labeled “ Mexico, Tamaulipas, Atlas Cumbres, 12 mi. W. Cd. Victoria,  February 18, 1986, R. Jones(1, TAMU).  Paratype: MEXICO: Rancho del Ciclo, Tamaulipas,  May 1954, J. Heckenla:ble [?, not legible] ( 1 ♂, UMINN).   Etymology:From the Latin omnino(entirely) and niger(black), referring to the entirely black color of this species.   Remarks: This species cannot be associated with described females. The black color is similar to  P. annulatus, but  P. omninonigerlacks punctures on the head, has a black spot under the stigma of the forewing, and has most of the legs beyond the trochanters brown to dark orange. 1986-02-18 TAMU Male & Atlas Cumbres & W.
