Diagnosis. Distinguished from the other three species of Heptagonatocerus by its small body size, fl3 (except base) and fl4 white, contrasting strongly with the remaining, dark brown funicle segments (Fig. 133), and fore wing with two transverse brown bands separated by a clear area (Fig. 135).
Description. FEMALE. Body length 768–922 (n=10). Colour. Head, scape except radicle, mesosoma and legs mainly dark yellow; radicle light yellow, pedicel brown, flagellum dark brown except fl3 other than base and fl4 white; pronotum, narrow longitudinal line along notaulus, scutellum laterally and along transscutal articulation between notauli light yellow; mesosoma dark yellow with brown transverse band on gt4 and gt5 and darker spot on spiracle. Fore wing with transverse brown band beyond venation and lighter brown suffusion in apical two fifths (Fig. 135). Head. Width 232 (n=1). Antenna. Funicle segments fl2–fl6 each with 2 mps, fl1 and fl7 without mps, each segment with normal setae, more dense on apical segments (Fig. 133). Antennal measurements (n=2), length/ width (ratios of flagellar segments): scape 214–251/34–40, pedicel 56–59/30–38, fl1 45–53/24–27 (1.88–2.20), fl2 73–90/26–28 (2.80–3.39), fl3 69–84/25–27 (2.54–3.39), fl4 66–81/26–28 (2.32–3.08), fl 5 28–64 /31–34 (1.73–2.06), fl6 55–71/39–41 (1.37–1.82), fl 7 30–32 /40–48 (0.66–0.74), clava 149–163/60–68 (2.40–2.72). Mesosoma. Propodeum apparently without median carina. Wings. Fore wing length (n=3) 752–872, width 204–235, length/ width 3.69–3.89, longest marginal seta 87–93. Hind wing (n=2) length 579–694, width 20–23, longest marginal setae 82–90. Metasoma. Ovipositor sheath length (n=2) 516–594, distinctly longer than metatibia length (278– 363) and distinctly exserted beyond apex of gaster.
MALE. Body length 1100 (n=1, card mount). Colour. Body dark yellow except flagellum dark brown constrasting strongly with yellow scape and pedicel; gaster brown, gt4 and gt5 darker than in female. Antenna. Total flagellar length 1495. Metasoma. Genitalia not examined (slide mount of unique male not prepared).
Etymology. The species name is a Latin adjective meaning small, referring to the very small size of this species compared to others in the genus.
