An unusual Cretaceous beetle with affinity to Anamorphidae (Coleoptera: Coccinelloidea)
Coccinelloid beetles have a sparse fossil record in the Mesozoic. Here, we describe and illustrate an unusual coccinelloid beetle, <i>Yassibum yoshitomii</i> gen. et sp. nov., from mid-Cretaceous Kachin amber. <i>Yassibum</i> 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 <i>Yassibum</i> is most likely related to the family Anamorphidae. The alternative placements are critically evaluated based on our comparison of the morphology.
