ARESCON Walker, 1846

( Figs 43–49 )

Arescon Walker, 1846: 50 . Type species: Mymar dimidiatus Curtis, 1832 , by monotypy. See Huber et al. (2020) for generic synonyms and their type species.

Diagnosis. Vertex with pale lines surrounding ocelli rectangular and also connected by pale lines extending from each corner of stemmaticum to supraorbital trabeculae ( Fig. 44 ); female antenna with funicle 5-segmented ( Fig. 45 ); fore wing with venation extending at least 0.7× wing length ( Fig. 48 ); marginal vein 2× as long as submarginal vein, more than 2× as long as parastigma and with 2 distal macrochaetae; postmarginal vein apparently absent.

Discussion. Arescon belongs to the Arescon group of genera. In the Afrotropical region this is the only genus in the group. Based on the long fore wing venation, it is most similar to a group that includes Borneomymar and Chrysoctonus . These are the only genera with a fore wing venation at least 0.6× wing length (in Chrysoctonus , only males have wings).

Afrotropical hosts. Unknown.
