Cladistic analysis of the tribe Eburiini Blanchard, 1945 and revalidation of the tribe Dychophyiini Gistel, 1848 (Coleoptera: Cerambycidae)

Abstract

AbstractEburiini is currently composed of 22 genera and 262 species, with a geographical distribution restricted to the Americas. Herein, we present a cladistic analysis of Eburiini and its genera, using a matrix with 82 terminal taxa, 52 from the ingroup (including representatives of all recognized genera) and 30 from the outgroup, and 105 characters of the adult morphology. The matrix was analysed under implied weights, and the tribe was not recovered as monophyletic. In order to recover the monophyly of the tribe, two genera of Heteropsini, Heterops and Eburiola, were transferred to Eburiini. The transfer of Heterops, type genus of Heteropsini, results in these two tribes being considered synonyms, with the name Eburiini having priority. The tribe Dychophyiini was resurrected to include the genera that were allocated to Heteropsini and were not transferred to Eburiini. The subgenus Eburia (Eleutho) was recovered as monophyletic and is herein elevated to genus rank. The genera Opades and Pantomallus are synonymized. The species Eburia sordida and Eburia fuliginea were transferred to Pantomallus, recovering the monophyly of the genus. With the synonymy of Opades, the transfer of the genera Heterops and Eburiola, and the new status of Eleutho, Eburiini is composed of 24 genera and 268 species.
