Chrysolina przewalskii (Jacobson, 1895) and Ch. lucidula Chen, 1934 are redescribed based on the type specimens. Neotype of Ch. przewalskii is designated. Ch. daccordii Lopatin, 2000 is a new junior synonym of Ch. juldusana (Lopatin, 1962); Ch. daosana Lopatin, 2007 is a new junior synonym of Ch. tani Lopatin, 1998; Ch. burchana Lopatin, 1998 is a new junior synonym of Ch. przewalskii (Jacobson, 1895). Ch. lucidula Chen, 1934 described from a mislabeled specimen is a new junior synonym of the South European Ch. lucida (Olivier, 1807). Ch. hyrcana var. cyanescens (Jacobson, 1894) is synonymized with Ch. circumducta (Ménétriés, 1848) and is merely a color form of the latter species.
