Remarks	The genus Ceutorhynchoides Colonnelli (Ceutorhynchini, Ceutorhynchinae) was recorded for the first time from Japan, with descriptions of two new species; C. squamatus sp. nov. (Ryukyus) and C. styracis sp. nov. (Honshu, Shikou, and Kyushu). In addition, Hainokisaruzo gen. nov., which is related to Ceutorhynchoides, was established for three Japanese species: H. japonicus sp. nov. (type species; Honshu and Kyushu), H. nipponensis (Hustache), comb. nov. (Honshu and Kyushu), and H. infuscatus sp. nov. (Honshu, Shikoku, Kyushu, and Ryukyus). Based on morphological reason, Ceutorhynchoides bengalensis Colonnelli, C. notatus Colonnelli, C. topali Colonnelli, C. subcostulatus (Hustache), and C. sinensis Korotyaev from the Oriental Region are transfferred to Hainokisaruzo (comb. nov.). A key to species, habitus photographs, and illustrations and SEM photographs of important characters were provided for the Japanese species of both genera. The following host association records were also given in this paper: Ceutorhynchoides styracis with Styrax japonica Siebold et Zuccarini (Styracaceae), Hainokisaruzo japonicus with Symplocos glauca (Thunberg) Koidzumi (Symplocaceae), and H. nipponensis with Symplocos chinensis (Loureiro) Druce (Symplocaceae).
