摘要

Yan, Z., Bai, M. & Ren, D., 2012. A new genus and species of fossil Hybosoridae (Coleoptera: Scarabaeoidea) from the Early Cretaceous Yixian Formation of Liaoning, China. Alcheringa, 1-7. ISSN 0311-5518. A new genus and species of a well-preserved fossil hybosorine (Coleoptera: Scarabaeoidea: Hybosoridae), Fortishybosorus ericeusicus Yan, Bai & Ren, is described and illustrated from the Early Cretaceous Yixian Formation of Huangbanjigou, Liaoning Province, China. The new fossil can be differentiated from all other hybosorines by its large and strong mandibles, two spurs of different length on the end of the metatibia, three teeth on the outer margin of the protibia, short and robust legs, no striae or tubercles on the elytra, and two well-developed wings. This is the first record of hybosorids from the Early Cretaceous Yixian Formation of Huangbanjigou, Liaoning Province, China.
