Alloeuzercon seemani gen. nov. and sp. nov. of Euzerconidae (Acari: Mesostigmata) associated with passalid beetles from China.

Alloeuzercon seemani Sun, Jin & Yi gen. & sp. nov. (Acari: Mesostigmata: Celaenopsoidea: Euzerconidae) associated with passalid beetles (Coleoptera: Passalidae) is described, representing the first record of the family Euzerconidae from China. The new genus bears a close resemblance to the genera Euzerconoides and Paraeuzercon, prompting us to update the key to genera. [ABSTRACT FROM AUTHOR]
