Distribution.

Japan: Hokkaido.

Remarks.

As mentioned above, at present, Ch. aino is treated as Morphological group EII and EIII: Unit EII- 1, EII- 2, EIII- 1 and EIII- 2. Considering the distribution range, two paratype specimens collected at “ Mt. Sora-numa ” (0000003028, 0000003030) ought to be considered Unit EII- 2, but after checking external traits, they were found to be Unit EIII- 1. Both holotype and paratype correspond to Unit EIII- 1, but one of the paratypes, (0000002423) collected in Nukabira has different hind wings and median lobe of the male genitalia. Nukadaira is located in the northern part of the Tokachi region of Hokkaido, and Unit F ( Ch. porosirensis ) is distributed here. However, this paratype differs from Unit F in external traits such as the shape of the median lobe and hind wings. The apex of the median lobe of this paratype gradual expands toward the apex in dorsal view (Fig. 5 C, D View Figure 5 ), the hind wing is remarkably degenerated and furnished with four veins (Fig. 3 J View Figure 3 ). The pronotum is greenish blue with a sheen and the elytron is yellowish orange with a sheen (Fig. 4 C View Figure 4 ). These features are similar to Unit EII- 2 distributed from the southern area of Ishikari District to the western part of Iburi District. Since it is unlikely that this unit has an exclave distribution, we suspected that it was mislabeled. However, we found two other specimens (TT 0000346, 347) collected at Nukabira on different dates by different collectors that are very similar to this paratype. This indicates that the label of the paratype is not mistyped and there is a possibility that Unit EII- 2 or another similar unit is distributed in Nukabira, but the number of specimens is too small to properly characterize the identity these populations.

All type labels of this species are mistyped as Chrysolina “ ainu ”, instead of Chrysolina aino . In the original description, the species epithet was given as “ aino ”, and subsequent literature has consistently used this spelling. Upon inquiry, Dr Takizawa, the author of the original description, confirmed that the spelling “ ainu ” found on the type labels was a handwritten mistake, and that Chrysolina aino is the correct and valid name.

In Bieńkowski (2007), Ch. aino is recorded from Korea for the first time, but this record is excluded here because it is not an appropriate distribution assuming that Ch. aino is treated as Morphological group EII and EIII: EII- 1, EII- 2, EIII- 1 and EIII- 2, as indicated above.

According to Bieńkowski (2001), there are two specimens collected from Honshu, Kobe as “ Additional specimens ”. From examining them, the habitus and genitalia agree with Unit C- 1. This record, as well as the record of Ch. angusticollis from Yokohama, need to be re-examined because no other records or other specimens have been found, and we will refrain from recording it here as a distribution.
