STEPHANODES Enock, 1909

( Figs 255–260 )

Stephanodes Enock, 1909: 457 . Type species: Stephanodes elegans Enock, 1909 , by monotypy. See Huber et al. (2020) for generic synonyms and their type species.

Diagnosis. Vertex with large shallow depressions outside each ocellus ( Fig. 256 ); scape with inner surface rasp-like ( Fig. 257 ); mesonotal spiracle much closer to anterior apex of notaulus than to dorsal apex of prepectus ( Fig. 259 ); mesosoma and metasoma smooth and shiny ( Figs 259, 260 ); fore wing with parastigma slightly elongate ( Fig. 258 ); petiole attached to gastral sternum posteriorly.

Discussion. Stephanodes belongs to the Polynema group of genera as defined by Triapitsyn & Berezovskiy (2007). In the Afrotropical region this group also includes Acmopolynema , Ganomymar , Mymar , Mymarilla , Palaeoneura and Polynema . Stephanodes is unique in having the mesonotal spiracle advanced, closer to the anterior apex of the notaulus than to the dorsal apex of the prepectus.

Afrotropical hosts. Unknown.
