About raising of the status of the subfamily Eremazinae (Coleoptera: Scarabaeoidea: Scarabaeidae) with description of new taxa from the Mesozoic in China
Yixianscarabaeus gen. n. with 2 new species Y. sulcatus sp. n. (type species) and Y. tenuestriatus sp. n. from the Yixian Formation of China are described. This genus can be attributed to the family Eremazidae stat. n. based on the posteriorly open procoxal cavity. Diagnosis of the genus: mandibles...

description | Yixianscarabaeus gen. n. with 2 new species Y. sulcatus sp. n. (type species) and Y. tenuestriatus sp. n. from the Yixian Formation of China are described. This genus can be attributed to the family Eremazidae stat. n. based on the posteriorly open procoxal cavity. Diagnosis of the genus: mandibles not produced beyond apex of clypeus; eye partly divided by genal lobe; apex of pronotum with leathery border; posteriorly open procoxal cavity with a clearly visible trochantin; mesocoxae contiguous, positioned at an right angle; meso- and possible metatibia with 2 transverse carinae on external surface; meso- and metatibial spurs are contiguous. Yixianscarabaeinae subfam. n. for this genus is proposed. |
