Psylla moiwasana Kuwayama, 1908: 175 .

Cacopsylla moiwasana; Inoue (2010: 350).

Psylla midoriae Miyatake, 1963: 339; synonymised with Cacopsylla moiwasana by Cho et al. (2019a: 148).

Cacopsylla midoriae; Inoue (2004a: 400).

Psylla jezoensis Miyatake, 1963: 349; synonymised with Cacopsylla moiwasana by Cho et al. (2019a: 148).

Cacopsylla jezoensis; Inoue (2010: 348).

Acizzia moiwasana; Kwon & Kwon (2020: 103).

Psylla micromeli Konovalova, 1981: 14, syn. nov.

Type material examined. Paratypes of Psylla micromeli . Russia: 2 ♂, 2 ♀, Primorsky Krai, Spassky District, western spur of Siny (Blue) Range, environs from Evseevka, 19.vi.1978 (Konovalova), (IBSS, slide mounted) .

Distribution in Korea. GB, GG, GN, GW, JB (Cho et al. 2019a; Kwon & Kwon 2020) (NIBR, SNU).

Host plant. Sorbus alnifolia (Sieb. & Zucc.) K.Koch (Rosaceae) (Cho et al. 2019a).

Comments. Kwon & Kwon (2020) transferred Cacopsylla moiwasana to Acizzia “justified by characters of the head, forewing and male genitalia”. Last instar immatures of C. moiwasana have 7-segmented antennae and marginal sectasetae on the caudal plate (Inoue 2004), a combination of characters found in many Cacopsylla spp. but not in Acizzia which has 9-segmented antennae and lacks marginal sectasetae on the caudal plate (Burckhardt & Mifsud 1998). We therefore adopt the generic combination used by Inoue (2004) and Cho et al. (2019a): Cacopsylla moiwasana, comb. rev. from Acizzia .

The comparison of specimens of Cacopsylla moiwasana from Korea (SNU) and paratypes of Psylla micromeli (IBSS) showed that they are conspecific. Here we formally synonymise the two nominal species.
