(Figs 47–55)

Material examined. Holotype female ( UAT), Mexico, Tamaulipas, 6 km NE of Miquihuana , 23°36.125’N, 99°42.45’W, 2200–2600 m, 24.X.2008, coll. A.I. Khalaim.GoogleMaps 

Description. Female. Body length 3.5 mm. Fore wing length 2.9 mm.

Head, in dorsal view, distinctly constricted and rounded posterior to eyes (Fig. 48); gena 0.85× as long as eye width. Eyes glabrous. Clypeus lenticular in front view, about 2.5× as broad as long, almost flat in lateral view, smooth in lower half and scabrous with several very fine punctures in upper half, separated from face by distinct furrow. Palp formula 4+3. Mandible moderately slender, weakly tapered in basal half; upper tooth distinctly longer than the lower. Malar space almost as long as basal mandibular width. Antennal flagellum (Fig. 49) basally slender, probably filiform, with over 15 flagellomeres (apices of both flagella missing); second flagellomere almost 2.5× as long as broad. Face with weak elongate median prominence. Face and frons granulate, impunctate, dull. Vertex shallowly granulate, impunctate, weakly shining. Gena polished, with very fine setiferous punctures. Occipital carina complete. Hypostomal carina absent.

Mesosoma granulate, impunctate, dull; mesopleuron centrally (above and below the foveate groove) more or less smooth and shining. Notaulus absent (Figs 47, 48). Scutellum with lateral longitudinal carinae present only at its extreme base (Fig. 51). Foveate groove (Fig. 50) long, S-curved, extending across mesopleuron but not reaching neither front nor hind margin of mesopleuron, with transverse wrinkles extending downwards. Propodeal spiracle separated from pleural carina by one diameter of spiracle ( Fig. 53View FIGURES 53–55). Propodeum with all carinae strong (Fig. 51); basal keel 0.9× as long as apical area; apical area flat, very broad and obtusely pointed anteriorly; apical longitudinal carinae more or less complete, convergent towards transverse carina.

Fore wing with second recurrent vein (2m-cu) postfurcal. Intercubitus (2rs-m) thickened, as long as abscissa of cubitus between intercubitus and second recurrent vein (abscissa of M between 2rs-m and 2m-cu). First abscissa of radius (Rs+2r) almost straight, much longer than width of pterostigma. First and second abscissae of radius (Rs+2 r and Rs  ) meeting at slightly acute angle. Metacarpus (R1) not reaching apex of fore wing. Second abscissa of postnervulus present, thus brachial cell is clearly closed posteriorly. Hind wing (Fig. 52) with nervellus (cu1&cu-a) slightly reclivous. Legs slender. Tarsal claws moderately long and weakly curved, not pectinate.

First tergite 4.2× as long as posteriorly broad, smooth; in cross-section trapeziform basally and round centrally; with upper margin almost straight in basal 0.65 and strongly arcuate in apical 0.35 ( Fig. 53View FIGURES 53–55); postpetiole distinctly wider than petiole in dorsal view. Glymma deep, situated in posterior 0.6 of tergite, joining by deep and sharp furrow to ventral part of postpetiole ( Fig. 53View FIGURES 53–55). Second tergite twice as long as anteriorly broad ( Fig. 54View FIGURES 53–55). Thyridial depression 3.0× as long as broad. Ovipositor long and very slender, weakly bent upwards, with weak dorsal subapical depression and stronger upcurved at extreme apex ( Fig. 55View FIGURES 53–55); sheath about 3.0× as long as first tergite.

Head, mesosoma and first metasomal segment black. Palpi, mandible (teeth dark reddish brown) and lower 1/3 of clypeus brownish yellow. Scape and pedicel of antenna dark brown, flagellum black. Tegula yellow. Wings hyaline. Pterostigma brown. Fore and mid legs brownish yellow. Hind leg with coxa extensively darkened with brown, trochanters brownish yellow, femur brown (paler at base and apex), and tibia and tarsus dirty brown (tibia with weak subbasal pale band and basitarsus pale at base). Metasoma posterior to first tergite predominantly dark brown with brownish yellow markings laterally and ventrally; tergite 2 dorsally with transverse band posteriorly and narrow stripes on lateral margins in front 0.6 yellow ( Fig. 54View FIGURES 53–55); tergite 3 with posterior pale band weaker than on tergite 2.
