Diagnosis. Clistopyga oaxacana may be distinguished from all other species of the C. calixtoi species group by the following combination of characters: mesosoma mostly orange ( Figs 42A, 42C–D ); pronotum tricoloured, white cream. orange, and black ( Figs 42A, 42C ); mesopleuron entirely orange, subalar prominence white cream ( Figs 42A, 42C ); propodeum mostly orange, without white cream or yellow marks ( Figs 42C–D ); metasoma without posterior defined white or yellow marks on tergites II–VI, sometimes with posterior rim finely yellow ( Figs 42A, 42E ); clypeus slightly convex, almost flat ( Figs 42B–C ); submetapleural carina strong on anterior 0.4–0.5 of metapleuron ( Fig. 42C ); ovipositor very weakly up-curved at posterior 0.4–0.5; ovipositor sheath anteriorly with very distinct denticles on ventral margin ( Fig. 42G , arrow).

Remarks. Additional characters to the original description are as follow: female with hypostomal carina not lamelliform posteriorly to mandible; clypeus slightly convex, almost flat in profile; anterior half of median lobe not conspicuously prominent, confluent with posterior half; propodeal spiracle about 0.11 the length to anterior end of pleural carina; hind leg with femur about 3.85× as long as high.
