Diagnosis. Asthenara tecuexe sp. n. can be distinguished from all other described species of Asthenara by the combination of the following characters: 1) Propodeal carina absent, 2) Metasoma, hind coxa, fore and middle femora reddish yellow.

Description. Female (holotype). Fore wing 4 mm, body 5.6 mm.

Head. Antenna thin, with 36 flagellomeres. Frons without a median projection just above antennal sockets ( Fig. 1 ). Face and clypeus smooth, mat. Face approximately 1.9 × as wide as long, with indistinct, uneven and fine punctures; median portion weakly and longitudinally convex. Clypeus slightly raised towards apical margin, with very sparse, fine and distinct punctures. Upper tooth of mandible distinctly shorter than lower tooth. Malar space approximately 0.3 × as long as basal width of mandible. Gena impunctate, narrowed posteriorly ( Fig. 2 ), in lateral view approximately 0.7 × as long as width of eye. Vertex impunctate, hind-median portion slightly impressed. Interocellar area slightly convex. Frons impunctate. Occipital carina complete, dorsomedian portion not concave.

Mesosoma. Anterior portion of pronotum smooth with fine punctures. Epomia present. Mesoscutum with fine punctures. Notaulus present, anterior 0.3 sharp. Scutellum convex, with fine punctures, basal 0.3 with lateral carina. Postscutellum weakly convex. Subalar prominence strongly convex. Mesopleuron ( Fig. 3 ) and metapleuron smooth and shining. Epicnemial carina strong, upper end not reaching subalar prominence. Submetapleural carina strongly, anterior portion evidently convex. Fore wing with R intercepting pterostigma just before its middle. Areolet not petiolate. 2mcu with single bulla. Hind coxa smooth. Propodeum without carinae, except for pleural carinae ( Fig. 3 ).

Metasoma. T1 approximately 2.5 × as long as apical width, strongly convergent toward base, median dorsal carinae indistinct. Dorsolateral carinae weak, subbasal portion near spiracle indistinct. Ventrolateral carinae complete. Spiracle convex, located slightly before middle of T1. T2 trapeziform, approximately 0.6 × as long as apical width. T3 approximately 0.5 × as long as apical width. Ovipositor sheath approximately 0.8 × as long as apical depth of metasoma, straight and thin ( Fig. 3 ). Ovipositor rather thin.

Color. Antenna basally, face, mandible, hind upper edge of pronotum, subtegular projection, tegula, fore and middle legs, hypopygium yellowish. Head dorsally, mesosoma (except hind upper edge of pronotum and subtegular projection), basal part of T1 black. Hind legs, metasoma except basal portion of T1 reddish.

Male. Similar to female except antenna with 35 flagellomeres; ventral profiles of hind coxae, hind portion of T 4 yellow.

Material : Holotype 1 female, Mexico, Guadalajara, 23.vii. [year unknown], leg. McClendon, ANSP ; Paratypes: 2 males, same data as holotype, ANSP .

Etymology. The species epithet refers to the Tecuexe , extinct indigenous peoples of Mexico.
