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.
