Popis: Morrisia Santos-Silva, Nascimento and Wappes, gen. nov. Etymology. Derived from ���Morris��� (after Roy F. Morris, II) and the suffix ���ia���. Named to honor and recognize our good friend, Roy F. Morris, II, Lakeland, FL for his notable expertise in finding new Cer- ambycidae species wherever he treads (he has collected the holotype of more than 100 described New World Cerambycidae species). Feminine gender. Type species. Adetus squamosus Chemsak and Noguera, 1995, here designated. Description. Body moderate-sized, cylindrical. Head retractile; frons transverse; antennal tubercles flat, widely separated; eyes from moderate to coarsely faceted, small, not or imperfectly divided (area between lobes with a single row of ommatidia or lacking them); lower eye lobes much shorter than gena; antennae surpassing middle of elytra in male, not reaching middle in female; scape short, slightly surpassing anterior margin of prothorax, slender in female; antennomere III much longer than scape; antennomere IV distinctly shorter than III; remaining antennomeres much shorter than IV, with similar length. Prothorax slightly longer than wide; sides unarmed; in side view, pronotum gradually inclined toward posterior margin from about middle, not tuberculate. Procoxal cavities closed posteriorly; prosternal process distinctly, gradually widened toward apex. Metaventrite not distinctly reduced. Elytra parallel-sided from humerus to distal quarter, then gradually rounded; in side view, dorsally sinuous; dorsal base with broad, elevated gibbosity, posterior two-thirds distinctly convex dorsally; without erect setae. Membranous wings present, well-developed. Legs short; femora gradually clavate. Abdominal ventrite V deeply excavated posterocentrally in female, not so in male. Remarks. Morrisia gen. nov. differs from Adetus as follows: elytra sinuous dorsally in side view; dorsobasal area of the elytra with gibbosity; abdominal ventrite V of female deeply excavated posterocentrally. In Adetus, the elytra are uniformly convex in side view, and do not have a basal gibbosity dorsally, and the abdominal ventrite V of female is, at most, longitudinally and slightly sulcate centrally, with distal area not or slightly and gradually inclined. Morrisia gen. nov. differs from Adetaptera gen. nov. by these same features but also by membranous wings being present (absent or brachypterous in Adetaptera).
