The oldest root-eating beetle from the Middle Jurassic of China (Coleoptera,Monotomidae)

Cai, C.-Y., ?lipiński, A. & Huang, D.-Y., 31.3.2015. The oldest root-eating beetle from the Middle Jurassic of China (Coleoptera, Monotomidae). Alcheringa 39,488–493. ISSN 0311-5518.

Jurorhizophagus alienus gen. et sp. nov., a new fossil root-eating beetle, is described and figured based on an exceptionally well-preserved impression fossil from the Middle Jurassic Daohugou beds (ca 165 Ma), Inner Mongolia, northeastern China. It represents the earliest fossil Monotomidae known to date. Jurorhizophagus can not be assigned to either of two subfamilies Monotominae or Rhizophaginae based on the unique combination of many unusual characters, including an 11-segmented antenna with a 3-segmented club, the presence of a distinct frontoclypeal suture and transverse pronotum with a median longitudinal groove. The discovery of a new genus from the Middle Jurassic highlights the antiquity of Monotomidae and provides new information about the phylogenetic relationships between Monotomidae and its allied families.
