Microterys ishiii Tachikawa, 1963a: 231.
Type material examined. LECTOTYPE: ♀ (here designated): Matsuyama, ex Pulvinaria aurantii on Pittosporum tobira, 10.vi.1959, T. Tachikawa (ELKU). PARALECTOTYPES: 4 ♀♀, same data as lectotype; 1 ♀, ex P. aurantii, 20.vi.1955, T. Tachikawa lgt.; 3 ♀♀, Kurume, ex P. aurantii, 5.ix.1962, K. Inoue lgt. (ELKU).
Distribution. Japan: Honshu, Kyushu, Shikoku (TACHIKAWA 1963a). China (NOYES 2016).
Comments. The species was initially misidentified as M. okitsuensis Compere, 1926 by ISHII (1928) and consequently TACHIKAWA (1963) proposed a new name for this species. We were not able to find any specimens labelled as M. okitusensis in Dr. Ishii’s collection, but we consider also the material in Dr. Tachikawa’s collection fitting the original description of M. ishiii as syntypes: ‘… specimens which were reared from Pulvinaria aurantii collected by me in Kyushu (Fukuoka; Oita) were not M. okitsuensis but M. ishiii. M. ishiii is very common and widely distributed in Honshu, Shikoku and Kyushu, and is an important parasite of Pulvinaria aurantii.’; TACHIKAWA 1963). We have selected a lectotype from this material. This species runs very close to M. turanicus (Sugnojaev, 1965) in TRJAPITZIN’ S (1989) key. PILIPYUK & SUGONJAEV (1971) described M. insularis from Sakhalin and Kuril Islands, and this was later synonymised with M. turanicus by SUGONJAEV (1976). It is therefore possible that M. insularis is actually a synonym of M. ishiii, but this can only be confirmed by comparison with the relevant type material.
