The lectotype of Phyllopertha orientalis is designated here. We designated as a lectotype the specimen marked as var. B as the most consistent with the typical coloration of this species. All types are deposited in the collection of Natural History Museum, London, the United Kingdom (NHM) .

In the Palearctic catalogue, the nominative subgenus Exomala includes also E. ohdaiensis (Sawada, 1941) , E. pallidipennis ( Reitter, 1903) and E. okiwaensis ( Ohaus, 1925) [ Zorn et al., 2016]. Both editions of the Palaearctic Catalogue indicate that E. okiwaensis is endemic to Okinawa and has never been found outside the island, but according to the original description of this species [ Ohaus, 1925], it comes from Formosa (now Taiwan). In the publication about the subgeneric structure of Exomala and related genera [ Baraud, 1991], E. okiwaensis and E. ohdaiensis were not mentioned. Probably, the author did not have material available for studying the male genitalia (Baraud’s system is based mainly on the structure of the aedeagus). The study the male genitalia is necessary to clearly understand whether these species really belong to the nominative subgenus Exomala (and genus Exomala in generally). The imperfection of the genus system is supported by the fact that Blithopertha tarowana (Sawada, 1941) was assigned to the genus Exomala in the first edition of the Palaearctic catalogue [ Zorn, 2006] and then was included in Anomala in the second one [ Zorn, Bezdek, 2016]. The endophallus of E. orientalis was briefly described and illustrated by Shokhin [2017]. We publish here comparative images of the endophallus and the aedeagus of E. pallidipennis and E. orientalis here ( Figs 8–17).
