Abstract: Tribe Amelyrini Tshernyshev, Alekseev, Bukejs, Vasilenko, Legalov & Perkovsky, trib. nov. urn:lsid:zoobank.org:act: 152FEE2D-4A73-4D44-AC9A-0A246AC84986 Type genus: Amelyris Tshernyshev, Alekseev, Bukejs, Vasilenko, Legalov & Perkovsky, gen. nov., by present designation Diagnosis. Small beetles, 2.5–3.8 mm in length, characterized by the following combination of features: (1) head prognathous, small, rounded; (2) pronotum with lateral carinae; (3) elytra with longitudinal carinae and three regular rows of punctures between them, whereas humeri exhibiting an additional fine carina; (4) abdominal ventrites 1 and 2 connate; (5) antennal club friable (symmetrical or asymmetrical), composed of finely articulated segments; and (6) tarsi with tarsomere 1 distinctly reduced. Differential diagnosis. Representatives of Amelyrini trib. nov. are superficially similar to the species of Melyris or Falsomelyris (Melyrini), but can be distinguished in smaller body size (2.5–3.8 mm vs. 7–9 mm in Melyrini), in prognathous convex head (in contrast to orthognathous non-convex head in Melyrini), in pronotum with lateral carinae (vs. lateral margins lacking carinae or bearing a single longitudinal carina near the margin, e.g., in Melyris rufomarginatus), in elytral intercarinal spaces with three regular puncture rows (vs. irregular 3–4 rows in Melyrini), in abdominal ventrites 1 and 2 connate (in contrast to freely articulated in Melyrini), and in humeri with a distinct carina (vs. absent in Melyrini). Etymology. The tribe Amelyrini trib. nov. is named after the nominative genus Amelyris gen. nov., whose etymology is presented below.
