Notes - Based on the figures presented in the original description, Pachyserica taiwana (NOMURA, 1974) must be regarded as junior synonym of Serica pulvinosa FREY, the parameres of the two species being identical in shape. The type of Serica albosquamosa FREY shows no characters in external or genital morphology that permit its separation from S. pulvinosa FREY, consequently it is synonymized here, also. In order to avoid nomenclatural difficulties potentially arising from as yet unresolved systematic problems in the genera Pachyserica BRENSKE, 1897 and Serica MACLEAY, 1819 (e.g. possible secondary homonymy with Pachyserica albosquamosa BRENSKE, 1898), preference should be given to the name Serica pulvinosa, instead of Serica albosquamosa FREY. A high degree of similarity in male genital morphology suggests that this species is most closely related to Pachyserica nigroguttata (BRENSKE).
