Diagnosis. Distinguished from the other species of Heptagonatocerus by the fore wing with the two dark areas beyond venation joined by a longitudinal median brown streak ( Fig. 132 ) and funicle segments wide, with fl1–fl4 with length/width less than about 1.7 ( Fig. 131 ).

Description. FEMALE. Body length 2150–2076 (n=2). Colour. Head, mesosoma and petiole light brown or dark yellow; flagellum black; scape brown except white apically and dorsoapically, and pedicel yellowish; gaster light brown but gt1–gt5 darker brown dorsally and laterally; legs mostly light brown but metatibia except base dark brown; procoxa, metacoxa apically, and metatibia basally white. Fore wing behind parastigma with brown area fading apically, and beyond apex of venation with two brown medially and subapically, separated by white areas except for a narrow longitudinal brown band joining the brown areas submedially ( Fig. 132 ); hind wing clear, with faint brown suffusion medially beyond venation. Head. Head width 484 (n=1). Face submedially above clypeus with group of about 8 long setae. Antenna. Funicle segments fl2–fl6 each with 2 mps, fl1 and fl7 without mps ( Fig. 131 ), each segment with dense, short setae, thick dorsally and ventrally. Antennal measurements (n=1), length/ width (ratios of flagellar segments): scape 701/84, pedicel 86/62, fl1 144/83 (1.73), fl2 158/105 (1.50), fl3 154/114 (1.34), fl4 158/113 (1.40), fl5 146/112 (1.31), fl6 130/116 (1.12), fl7 61/98 (0.62), clava 453/138. Mesosoma. Propodeum with median carina short, not longer than sublateral carinae. Wings. Fore wing length (n=1) 1871, width 456, length/width 4.10, longest marginal setae 116. Hind wing length 1588, width 76, longest marginal setae 130. Metasoma. Ovipositor sheath length (n=1) 866, longer than metatibia length (738) and barely exserted beyond apex of gaster.

MALE. Body length 1766–1971 (n=3). Colour. Flagellum, mesosoma except pronotum, petiole, and gaster dorsally dark brown; scape, pedicel, face, gena below eye, pronotum and gaster laterally and ventrally lighter brown; vertex and occiput with narrow yellow lines around each ocellus, along dorsal and posterior orbits, from lateral ocelli to foramen magnum, and from mid ocellus to transverse trabecula apices; legs dark yellow except meso- and metacoxa, and metatibia dark brown. Antenna. Measurements (n=1): scape length (length/width) 221 (3.03), pedicel length (length/width) 72 (1.25), flagellar segment length: fl1 242, fl2 274, fl3 278, fl4 293, fl5 301, fl6 275, fl7 263, fl8 249, fl9 268, fl10 274, fl11 272; total flagellar length 2989; flagellar segments progressively widening from fl1–fl4 then narrowing from fl9–fl11, fl5–fl8 with most mps and strongly notched ventroapically; fl6 length/width 2.49, with about 14 mps. Metasoma. Genitalia with peculiar circular apodemes arranged vertically at anterior apex of aedeagus.

Etymology. The species name is a Latin adjective meaning magnificent.
