New Fossil Histerid Species from Cretaceous Burmese Amber (Coleoptera: Histeridae)

Four newly discovered Cretaceous genera and species are established in the family Histeridae. Phasmister cristatus Caterino, new genus, new species and Carinumerus maddisoni Caterino, new genus, new species are described in the Onthophilinae. Yethiha peregrina Caterino, new genus, new species and Druantia aeterna Caterino, new genus, new species are described in the Dendrophilinae. Additionally, Onthophilus yingae Jiang et al. is reassigned to Carinumerus. The new onthophiline genera share characters with the previously described Cretaceous histerid Cretonthophilus Caterino et al. and lack characters typical of extant Onthophilinae, and the three together may represent an early diverging lineage of this subfamily. The species of Druantia shares some features with extant Dendrophilinae, and some with Yethiha, so their systematic placement is less clear. A brief diagnostic catalog of all known Cretaceous Histeridae is provided.
