Figs 5 View Figure , 8A–C View Figure

Diagnosis

This species can be distinguished from all its congeners by a combination of the following characters: face distinctly broader than high ( Fig. 5A View Figure ), mesosoma with yellow stripes on mesoscutum anteriorly ( Fig. 5C View Figure ), metasoma with all tergites extensively pale medially ( Figs 5B–C View Figure ).

Etymology

The name of the species refers to the characteristic coloration of the metasoma.

METASOMA. Metasoma cylindrical, rather shining, granulate, impunctate, with isolated setae ( Fig. 5B View Figure ). T1 1.5 × as long as wide apically, with shallow median longitudinal impression, and bordered by lateral longitudinal carinae. Hind margin of first metasomal sternite at level of spiracles. T2 transverse. Thyridia absent. Hypopygium triangular in profile. Ovipositor sheath slender, 0.7 × as long as metasomal height.
