Diagnosis. Distinguished from the other three species of Heptagonatocerus by the funicle uniformly brown and basal segments narrow ( Fig. 122 ), and the fore wing with the brown spot just beyond apex of venation crossed by a narrow, darker, slightly curved longitudinal line that extends to the apical brown area ( Fig. 127 ).

Description. FEMALE. Body length 1306–1434 (n=3). Colour. Scape, pedicel, legs except sometimes metatibia, pro- and mesothorax, and gaster ventrally and usually laterally yellow; flagellum, head, scutellum (especially frenum), and at least gt4 and gt5 dorsally dark brown. Fore wing with brown spot just beyond apex of venation crossed by a narrow, darker, slightly curved longitudinal line that extends to the apical brown area ( Fig. 127 ). The extent of dark brown on the body varies considerably: one female has the entire meso-and metapleuron, and propodeum dark brown; another has less dark brown on the mesosoma (the propodeum is mostly yellow) ( Fig. 126 ) but almost the entire gaster is dark brown. Head. Head ( Figs 124 , 136–139 ) width 340 (n=1). Antenna. Funicle segments fl2–fl6 each with 2 mps, fl1 and fl7 without mps ( Fig. 122 ), each segment with normal setae, more dense on apical segments ( Figs 140, 141 ). Antennal measurements (n=1 or 2), length/width (ratios of flagellar segments): scape 382–420/43–51, pedicel 79/45–46, fl1 75–83/30 (2.52–2.74), fl2 128–132/ 32–33 (3.90–4.06), fl3 124/35 (3.51), fl4 125–127/40 (3.15), fl5 107–108/49 (2.21), fl6 100/68–73 (1.37–1.47), fl7 42/64–67 (0.63–0.68), clava 263–267/94–98 (2.72–2.81). Mesosoma. Propodeum with median carina not extending to dorsellum ( Fig. 143 ), sometimes not longer than sublateral carina ( Fig. 126 ). Wings. Fore wing length (n=2) 1395–1598, width 395–478, length/width 3.34–3.53, longest marginal setae 106–131. Hind wing length 1154–1195, width 169–189, longest marginal setae 138–149. Metasoma. Ovipositor sheath length (n=2) 682–699, distinctly longer than metatibia length (545–550) and slightly exserted beyond apex of gaster.

MALE. Body length 1024–1459 (n=10). Colour. Body dark brown except scape, pedicel, pronotum, notauli, scutellum laterally and legs except sometimes metatibia yellow. Antenna. Measurements (n=1): scape length/ width 3.08, pedicel length/width 1.35, flagellar segment length: fl1 146, fl2 156, fl3 168, fl4 163, fl5 167, fl6 164, fl7 164, fl8 152, fl9 153, fl10 144, fl11 140; total flagellar length 1720; fl6 length/width 3.29, with about 10 mps ( Fig. 123 ). Metasoma. Gaster as in Figs 128 and 130 . Genitalia as in generic description ( Figs 129, 130 ).

Etymology. The species is an apposition named after the country where all the specimens were collected.
