DESCRIPTION: Holotype female. Length 6.4 mm; head, mesosoma, base of T1, T6 black, apex of T1, T2–T5 dark red; femora, tibiae, tarsi dark red; antenna entirely black; tegula black to dark brown; palpi light brown; wings infuscate throughout, dark gray.
Head (figs. 2, 3, 52–54) moderately transverse in dorsal view, width 1.6 times length; vertex coarsely punctate, with granulate microsculpture; OOL short, lateral ocellus separated from inner orbit by less than one ocellar diameter; POL 1.4 times LOL; occiput coarsely punctate, with granulate microsculpture; occipital carina strongly raised, massive, crenulate; frons (fig. 53) rugulose-punctate, shining, above toruli with dense transverse wrinkles; frons fairly broad, IOS equal to greatest length of eye; toruli separated by distance of approximately one-half diameter of torulus, frons between toruli not projecting, flat; rim of torulus evenly raised; apical margin of clypeus broadly convex; area below eye (in normal position of malar sulcus) with fine granulate microsculpture; cheeks laterad of malar area coarsely punctate, without longitudinal sculpture; mandible short, bidentate, upper tooth only slightly longer than lower, without dense basal tuft of setae; maxillary palpal segment 4 distinctly expand- ed medially, subtriangular; A1 finely reticulate, greatest width beyond apical 0.6 of segment; length of A3 1.1 times length of A2.
Mesosoma (figs. 2, 3, 52, 54) as high as wide, length 1.4 times height in lateral view; pronotal shoulders coarsely punctate; lateral surface of pronotum with fine longitudinal rugulosity; netrion punctate-rugulose, with strong longitudinal sculpture; mesoscutum deeply punctate, with fine reticulate microsculpture; parapsidal lines present; scutellum coarsely punctate, with reticulate microsculpture, without longitudinal sculpture; median propodeal tooth moderately wide, two times as long as wide, pointed apically, longitudinally carinate; upper mesepisternum with strong longitudinal sculpture; fine foveae separating mesepisternum and mesepimeron extending from base of wing to coxal cavity; lower mesepisternum coarsely reticulate-punctate; mesepimeral hook longitudinally keeled; tegula finely punctate; apex of R 1 in forewing almost reaching costal margin; apex of forewing slightly surpassing apex of T4; R in hindwing with tracheate section short, broadly separated from hamuli by distance greater than its length; tibiae with fine, semidecumbent spines on outer surface.
Metasoma (figs. 3, 55) 3.4 times longer than greatest width; T1 distinctly wider than long; terga longitudinally rugose; apical emargination of female T6 moderately large, width greater than depth, female T6 anteromedially with field of granulate microscupture.
DIAGNOSIS: This species may be distinguished from most other species of Nixonia by the massively expanded occipital carina and the red basal metasomatic segments in the female.
ETYMOLOGY: Named in honor of Stewart Peck, collector extraordinaire.
