Time-scaled phylogenetic analysis of the Lamiini, its close relatives and some other widely distributed tribes of Lamiinae (Coleoptera, Cerambycidae)

The subfamily Lamiinae (Cerambycidae, Coleoptera) is striking due to its morphological diversity and species richness with intricate phylogenetic relationships. We inferred the phylogeny and evolutionary history of extant species of East of Marmara Basin, Turkiye, from the tribes Acanthocinini, Acanthoderini, Agapanthiini, Batocerini, Dorcadionini, Lamiini, Mesosini, Monochamini, Phytoeciini, Phrynetini, Pogonocherini (including Exocentrini) and Saperdini using partial mitochondrial cytochrome c oxidase-I (COI) and 16S rRNA and nuclear 28S rRNA gene regions (2257 base pair alignment length). The most recent common ancestor (MRCA) of Lamiinae members included in the analyses was dated [~]127 million years ago (Mya) in the Cretaceous. The MRCA of Dorcadionini, Lamiini and Monochamini was younger than the common ancestors of the other close tribes. There was a concurrence between resolutions of Maximum Likelihood (ML) and Bayesian analyses on the affiliations of Dorcadionini and Monochamini to Lamiini and the proximity of Batocerini to Lamiini, Acanthocinini to Acanthoderini, Phrynetini to Pogonocherini, and Phytoeciini to Saperdini. The COI-based Neighbor-Joining and ML gene trees suggest that the closest relatives of the extant Lamiinae species of East of Marmara Basin were the European conspecifics or congeners. Moreover, Paraleprodera and Lamia (Lamiini) were sisters to Imantocera (Gnomini), Oberea (Obereini) to Phytoecia Phytoeciini), and Hippopsis (Agapanthiini) to Omosarotes singularis Pascoe, 1860 (Acanthomerosternoplini). Our results support Dorcadionini, Gnomini and Monochamini as synonyms of Lamiini; and Obereini and Phytoeciini of Saperdini and suggest that the emergence of the living tribes included in this study was during Paleogene, and their intrageneric diversifications occurred during Cenozoic, mostly Neogene.
