HEPTAGONATOCERUS Huber, 2015 (Figs 157–162) Heptagonatocerus Huber, 2015: 33. Type species: Heptagonatocerus pulchellus Huber, by original designation. Diagnosis. Heptagonatocerus is distinguished from other members in the group by the following combination: face without subantennal sulci (Fig. 157); female antenna with funicle 7-segmented, and fu 7 wider than long and distinctly shorter than fu 6 (Fig. 158); propodeum with two short submedian carinae arising on side of petiole and usually also a median longitudinal carina (Fig. 161). Male antenna with basal flagellomeres fairly wide (Fig. 158). Discussion. Heptagonatocerus belongs to the Gonatocerus group of genera, treated formally as Gonatocerini by Huber (2015). In the Afrotropical region the group also includes Cosmocomopsis, Gonatocerus, Lymaenon, Octomicromeris, Tanyxiphium and Zeyanus. The reduced number of funicle segments occurs also in females of a few species of Lymaenon. Afrotropical hosts. Unknown. Important reference. Huber (2015).
