Remarks. Chrysolina aeruginosa has been recorded in Honshu and Hokkaido, Japan (CHUIO & KlMOTO 1960, KlMOTO 1964, TAKlZAWA 1970). However, KlMOTO (1964a) and TAKlZAWA (1970) are requotations of CHUIO & KlMOTO (1960), so I do not mention them here. CHUIO & KlMOTO (1960) treated Ch. pseudogeminata Bechyné, 1950 and a specimen of Ch. geminata sensu Jacoby nec Paykull recorded from Japan by JACOBY (1885) as synonyms of Ch. aeruginosa, and KlMOTO (1946b) designated the above two species as “instructa type ” of Ch. aeruginosa after checking the type in BMNH.
Later, KlMOTO & TAKlZAWA (1994) mentioned that, in reference to the figures of Ch. aeruginosa in MOHR (1963), the identification of Ch. aeruginosa in KlMOTO (1964b) is incorrect and the record should be corrected to Ch. difficilis, and he treated Ch. pseudogeminata and Ch. geminata sensu Jacoby nec Paykull as synonyms of Ch. difficilis.
BlEŇKOWSKl (2019) refered to the treatment of CHUIO & KlMOTO (1960) as inadequate because they did not check the type specimens of Ch. pseudogeminata. The type locality of Ch. pseudogeminata is “Kioto, Innai in N. Hondo”, and according to BlEŇKOWSKl (2019), the type series of Ch. pseudogeminata deposited in National Museum, Prague, Czech Republic contains two females conspecific with Ch. difficilis and one male conspecific with Ch. nikkoensis. BlEŇKOWSKl (2019) designated one of the females with the original label “TYPUS” as a lectotype of Ch. pseudogeminata and treated it as a synonym of Ch. difficilis.
JACOBY (1885) recorded “ Ch. geminata?” in “Hakodate”, Hokkaido but mentioned that the specimen may be another related species. This specimen is currently deposited in BMNH. Judging from the pictures of the specimen (Figs 7A, B), the specimen has the following external traits: latero-basal impression of pronotum deep; elytron has geminate rows of large punctures. These external traits agree with the diagnosis of the subgenus Hypericia. So, the specimen at least does not belong to the subgenus Allohypericia but to the subgenus Hypericia. Certainly, as JACOBY (1885) mentioned, there is a little difference in the punctuation of the elytra, so I did not identify the specimen and refer to it as Chrysolina (Hypericia) sp. here.
Incidentally, the key of Ch. aeruginosa in TAKlZAWA (1970) is based on specimens from China deposited in SEHU (SEHU: TT0000120-0000123) (Takizawa, pers. comm.).
From the above, it is unclear why CHUIO & KlMOTO (1960) treated Ch. geminata sensu Jacoby nec Paykull and Ch. pseudogeminata as Ch. aeruginosa but all of these records (CHUIO & KlMOTO 1960, KlMOTO 1964, TAKlZAWA 1970) from Japan are based on misidentifications. Therefore, Ch. aeruginosa is not distributed in Japan.
Distribution. East Kazakhstan, Russia (Siberia, Far East), Mongolia, N and NW China (BlEŇKOWSKl 2019).
