Arescon Walker 1846

ARESCON Walker, 1846 (Figs 40–44) 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. Funicle 5-segmented (Fig. 41); vertex with pale lines surrounding ocelli rectangular and also connected by pale lines extending from each corner of stemmaticum to supraorbital trabeculae (Fig. 40b); mandible with 4 teeth (Fig. 40a); dorsellum diamond-shaped, the anterior and posterior margins not parallel (Fig. 43); fore wing with venation extending at least 0.7× wing length (Fig. 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); 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? Important reference. Ogloblin (1957c) [as Xenomymar Crawford].
