Abstract
We report new discoveries of diverse Hydrophiloidea (Staphyliniformia) from the Albian (Early Cretaceous) Jinju Formation, South Korea, including the genera Laetopsia Fikáček et al., 2012 and Cretotaenia Ponomarenko, 1977, a new species of Laetopsia (Laetopsia leei sp. nov.), a species putatively shared with the Barremian Yixian Formation of China (L. cf. hydraenoides), an undetermined species of Laetopsia, and a new record of Cretotaenia pallida Ponomarenko are described and illustrated.
