Abstract:
The family Corylophidae is a moderately diverse coccinelloid beetle family. The fossil record of corylophid beetles is extremely sparse, with only one species formally described from the Eocene Baltic amber. Here we report a new corylophid genus and species, Xenostanus jiangkuni Li, Szawaryn & Cai gen. et sp. nov. , from mid-Cretaceous amber from northern Myanmar (ca. 99 Ma). Xenostanus is most distinctly characterized by the antenna with 10 antennomeres and the presence of metaventral and abdominal postcoxal lines. Our phylogenetic analysis suggested Xenostanus as sister to tribe Stanini. Based on its distinctive morphology and the phylogenetic results, Xenostanus is placed in the tribe Xenostanini Li, Szawaryn & Cai trib. nov.
