Two new species of Chrysomelobia (Acari: Heterostigmata: Podapolipidae) parasitic on Gonioctena rubripennis Baly (Coleoptera: Chrysomelidae; Chrysomelinae) in Japan.

Chrysomelobia matsuzawai sp. nov. and Chrysomelobia nipponica sp. nov. (Acari: Podapolipidae) are described from Gonioctena rubripennis Baly (Coleoptera: Chrysomelidae) collected in Japan. This is the first record of the genus Chrysomelobia Regenfuss, 1968 in Asia. Adult females of the type species for Chrysomelobia, Chrysomelobia mahunkai Regenfuss, 1968, were recollected from female specimens infesting a Gonioctena sp. in Germany. An updated key to all species of Chrysomelobia is provided. [ABSTRACT FROM AUTHOR]
