| Popis: | A new subgenus of Tenebroides, Polynesibroides subgen. nov., is established for six potentially extinct beetles, Tenebroides atiu, T. moorea, T. raivavae, T. rimatara, T. tubuai and T. mihiura spp. nov., described from the Cook, Austral and Society Islands based on subfossil fragments, and the extant T. tahiti sp. nov. from the island of Tahiti, Society Islands. Here we present the first detailed time-scaled phylogeny of the superfamily Cleroidea inferred from our four-gene dataset, including T. tahiti. Bayesian tip-dating, incorporating 17 fossils, estimated that Cleroidea appeared at the end of the Triassic (~210 Mya). The split of Biphyllidae + Byturidae + Phloiophilidae was reconstructed at ~204 Mya, followed by Early Jurassic separation of Trogossitidae (~200 Mya), Acanthocnemidae (~197 Mya), stem Cleridae–Thanerocleridae–Chaetosomatidae (~194 Mya), Peltidae, Lophocateridae, Decamerinae and the melyrid lineage (~191 Mya). Trogossitidae diversified by separation of Kolibacia (~136 Mya) in the Cretaceous, followed by parting Temnoscheila + Nemozoma and Airora + Tenebroides lineages (~113 Mya). Tenebroides radiated ~75 Mya and T. tahiti diverged from Panamanian taxa in the Middle Eocene (~40 Mya). Fourteen morphological characters of Pacific trogossitids were analysed. Parallelodera, including the Panamanian species, is nested within Tenebroides being sister to Polynesibroides. Therefore, Parallelodera is classified as a subgenus of Tenebroides. Tenebroides fairmairei is placed in the subgenus Parallelodera. A Neotropical origin for Parallelodera and Polynesibroides is inferred. |
