Blastothrix erythrostetha (Walker, 1847)

Blastothrix kermivora Ishii, 1828: 117 , syn. nov.

Type material examined. Blastothrix kermivora : LECTOTYPE: ♀ (here designated) (No. 43), antenna and fore wing ( NIAES).

Additional material examined. 3 ♀♀, Ooyagyu, Nara, ex Kermes nakagawae , 13.v.1993, Y. Higashiura lgt., G. Japoshvili & Y. Higashiura det.; 3 ♀♀ (on slide), Kaguyama, Kashihara, Nara Pref., ex K. nakagawae on Quercus serrata , 24–28.v.1994, Y. Higashiura lgt., G. Japoshvili & Y. Higashiura det. ( YHYJ).

Comments. After comparing type material of B. kermivora with reliably identified material of B. erythrostetha deposited in the Francis Walker collection (Hope Department of Oxford University – HDOU, Oxford), British Museum of Natural History (BMNH, London) and samples from the Zoological Institute (ZIN, St. Petersburg) (see also JAPOSHVILI & KARACA 2004), we conclude that the two species are conspecific and therefore treat B. kermivora Ishii as a junior synonym of B. erythrostetha .
