ARESCON Walker, 1846 View in CoL

( Figs 40–44 View FIGURES 40–42 View FIGURES 43, 44 )

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

Diagnosis. Funicle 5-segmented ( Fig. 41 View FIGURES 40–42 ); vertex with pale lines surrounding ocelli rectangular and also connected by pale lines extending from each corner of stemmaticum to supraorbital trabeculae ( Fig. 40b View FIGURES 40–42 ); mandible with 4 teeth ( Fig. 40a View FIGURES 40–42 ); dorsellum diamond-shaped, the anterior and posterior margins not parallel ( Fig. 43 View FIGURES 43, 44 ); fore wing with venation extending at least 0.7× wing length ( Fig. 42 View FIGURES 40–42 ); marginal vein 2× as long as submarginal vein more than 2× as long as parastigma and with 2 distal macrochaeta, the second one at about midpoint of marginal vein length; postmarginal vein apparently absent ( Fig. 42 View FIGURES 40–42 ); tarsi 5-segmented.

Remarks. Arescon belongs to the Arescon group of genera. These are the only genera with a fore wing venation at least 0.6× wing length (in Chrysoctonus , only males have wings). Arescon is most similar to Tinkerbella , which differs by the hind wing without setae along most of its anterior margin, frenum with a faint longitudinal median sulcus, and tarsi 4-segmented.

Neotropical hosts. Hemiptera : Membracidae ?
