Mesosoma unusually long and narrowed; hypopygium very large and heavily sclerotised, in profile truncate at apex; basal field of T2 rather small, subrectangular and with a sculpture of fine confused striation (fig. 67) [flagellum very short, three preapical segments slightly transverse; T1 more or less parallel-sided; pterostigma rather broad].
Papp (1986). Head in dorsal view less transverse, (1.7-)1.8 times broader than long. Second tergite less transverse, 1.6-1.7 times wider behind than long medially, first tergite fully parallel-sided (Fig. 62); hind half of first tergite and entire second tergite densely rugose, not shiny. Metasoma from third or fourth segment more or less compressed laterally. Hypopygium heavily sclerotized, in lateral view its hind margin distinctly arched, apically truncate (Fig. 63). Pterostigma 2.3-2.5 times longer than wide, issuing radial vein distinctly distally from its middle; rl and cuqul about equal in length (Fig. 64). Black, legs dark coloured.
