Monné, Miguel A., Nascimento, Francisco E. De L., Monné, Marcela L. & Santos-Silva, Antonio, 2019, New records, new genera, and new species in Acanthocinini (Lamiinae) from the Neotropical region, and new synonym in Cerambycinae (Coleoptera, Cerambycidae), Zootaxa 4624 (4), pp. 491-506 : 494-496

Vitacinis gen. nov.

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.
