Diagnosis. Distinguished from the other three species of Heptagonatocerus by the fore wing with the two dark areas beyond venation separated entirely by clear area, the uniformly dark brown flagellum ( Fig. 121 ), and propodeum with median carina extending to dorsellum.

Description. FEMALE. Body length 1740–2022 (n=7). Colour. Body uniform dark yellow, except flagellum almost black ( Fig. 121 ). Fore wing behind parastigma with brown area fading apically, and beyond apex of venation with three entirely separated brown areas: behind base of parastigma, medially and apically ( Fig. 121 ); hind wing clear, with faint brown suffusion medially beyond venation. Head. Width 480 (n=1). Antenna. Funicle segments fl1–fl6 each with 2 mps, fl7 without mps, all with short setae, thick dorsally and ventrally, and more densely spaced on apical segments. Antennal measurements (n=1), length/width (ratios of flagellar segments): scape 633/84, pedicel 83/57, fl1 158/70 (2.26), fl2 123/77 (1.60), fl3 130/77 (1.69), fl4 129/78 (1.65), fl5 117/73 (1.60), fl6 111/81 (1.37), fl7 52/83 (0.63), clava 410/138. Mesosoma. Propodeum with median carina extending to dorsellum. Wings. Fore wing length (n=1) 1870, width 512, length/width 3.65, longest marginal setae 118. Hind wing length 1459, width 77, longest marginal setae 125. Metasoma. Ovipositor sheath length (n=1) ~ 426, shorter than metatibia length (654) and barely exserted beyond apex of gaster.

MALE. Unknown.

Etymology. The species name is a Latin adjective meaning pretty, referring to the nicely patterned fore wing.
