“…Only the fossil genus was allowed to move freely across the backbone tree. In order to perceive the uncertainty of the fossil placement, the parsimony scores of the trees with alternative placements of the fossil were mapped to the corresponding branches of the backbone tree (Li et al., 2024 ). The results were visualized with the R package ggtree 6.5.2 (Yu, 2020 ; Yu et al., 2017 ) and graphically edited with Adobe Illustrator CC 2017.…”

Beetles have a remote evolutionary history dating back to the Carboniferous, with Mesozoic fossils playing a pivotal role in elucidating the early evolution of extant families. Despite their exceptional preservation in amber, deciphering the systematic positions of Mesozoic trogossitid‐like beetles remains challenging. Here, we describe and illustrate a new trogossitid‐like lineage from mid‐Cretaceous Kachin amber, Foveapeltis rutai Li, Kolibáč, Liu & Cai, gen. et sp. nov. Foveapeltis stands out within the Cleroidea due to the presence of a significant large cavity on each hypomeron. While the exact phylogenetic placement of Foveapeltis remains uncertain, we offer a discussion on its potential affinity based on our constrained phylogenetic analyses.

Tenebrionoids are not uncommon in late Mesozoic ambers, but their paleodiversity remains poorly explored, partly due to the insufficiently defined families of the extant fauna. Here, we describe and illustrate a new tenebrionoid beetle from mid‐Cretaceous Kachin amber, Glyphonotum hsiaoi gen. et sp. nov., which exhibits an unusual form of pronotal sulcus and tarsi. Based on morphological comparison and phylogenetic analyses, we tentatively place Glyphonotum in the extant family Pythidae, representing the first Mesozoic fossil of this family.

Coccinelloid beetles have a sparse fossil record in the Mesozoic. Here, we describe and illustrate an unusual coccinelloid beetle, Yassibum yoshitomii gen. et sp. nov., from mid-Cretaceous Kachin amber. Yassibum stands out within the Coccinelloidea due to its notched profemora and the presence of antennal grooves on the elytral epipleura. Based on our phylogenetic analyses, we suggest that Yassibum is most likely related to the family Anamorphidae. The alternative placements are critically evaluated based on our comparison of the morphology.
