OOCTONUS Haliday, 1833

( Figs 204–209 )

Ooctonus Haliday, 1833a: 268, 1833b: 343 . Type species: Ooctonus insignis Haliday, 1833 , by subsequent designation by Westwood, 1839: 78. See Huber et al. (2020) for generic synonyms and their type species.

Diagnosis. Face without subantennal sulci ( Fig. 204 ); female antenna with funicle 8-segmented ( Fig. 205 ); pronotum entire ( Fig. 207 ); propodeum with diamond-like pattern of carinae, the incomplete median carina, costulae and plicae, defining a central pentagonal areole and, sublaterally, several (usually 4) submedian areoles ( Fig. 207 ); fore wing with hypochaeta next to proximal macrochaeta ( Fig. 206 ); petiole distinctly longer than wide; gt 1 in lateral view usually as long as remaining terga together ( Fig. 209 ).

Discussion. Ooctonus belongs to the Ooctonus group of genera. In the Afrotropical region it is the only genus in the group. Although Ooctonus was traditionally placed near the Gonatocerus group of genera it superficially resembles several genera in the Polynema group except for the obvious difference in number of funicle and tarsal segments. The position of the hypochaeta, close to the proximal macrochaeta, is more similar to members of the Polynema group than to members of the Gonatocerus group.

Afrotropical hosts. Unknown.
