Etymology . Latin, “vita” (life), cinis (ash), which means life through the ashes, and life after ruin; referring to the Museu Nacional, Universidade Federal do Rio de Janeiro ( Brazil ). In honor of all the researchers who work or worked in the MNRJ, which was destroyed by fire on September 2, 2018 . Masculine gender.

Type species . Vitacinis luziae sp. nov. , here designated. Description . Male . Body flattened, moderately slender. Head short, not elongate behind eyes; frons rectangular; genae, in its narrower area, about 0.2 times length of lower eye lobes; distance between upper eye lobes about three times width of one upper lobe; antennae 11-segmented, distinctly longer than body; scape gradually widened toward apex, without remarkably long setae, without apical cicatrix; antennomeres filiform, without tuft of setae or remarkably long setae. Prothorax transverse; lateral tubercle large, with nearly acute apex (apex placed at about posterior quarter); sides gradually divergent toward apex of lateral tubercle, then abruptly narrowed. Pronotum with five gibbosities: one irregular, rounded at apex, slightly elevate on each side after midlength; one moderately elevate, nearly conical on each side of anterior third (distance between then narrower than posterior gibbosities); another elongate, moderately elevate from posterior quarter to about midlength, placed centrally. Narrowest area of prosternal process 1/6 width of procoxal cavity. Narrowest area of mesoventral process 0.3 times width of mesocoxal cavity. Metaventrite short, about as long as prothorax. Elytra cuneiform; with slightly elevate basal crest without erect setae; dorsal surface with distinct carina from about anterior quarter to posterior quarter, closer to lateral margin than suture; humeral carina present only at anterior half; inclined lateral area with distinct carina from about anterior third to near apex; apex slightly obliquely truncate, with outer angle projected and sutural angle rounded; with distinctly sparse, moderately short erect setae. Femora pedunculate-clavate, without distinct long setae; metafemora not remarkably long. Tibiae cylindrical, slightly, gradually widened toward apex, without distinct long setae. Metatarsomere I longer than twice length of II–III together. Abdominal process remarkably large, causing the metacoxae to be distinctly apart; ventrite I laterally narrower than II; II–IV increasing in length; ventrite V moderately slender, remarkably long, about 2.5 times length of IV, distinctly narrowed posteriorly. Females unknown. Remarks . Vitacinis gen. nov. differs from all the other American genera of Acanthocinini by the abdominal ventrite V of males remarkably narrow and long, making it similar to that of females of some genera.
