Leontium multiplicatum P>8, 1946 is confirmed as a junior synonym of L. viride T=DBHDC, 1864 as was suggested by N6@6C: (1976 b). Key words: Coleoptera, Cerambycidae, Callichomatini, Synonym, Japan. Introduction There are three callichromatine species on the catalogue of Japanese Cerambycidae, though they have never been found from Japan since their discoverey (O=76N6H=> & N>>H6ID, 2007). After the revision of their type specimens, we have been able to identify them. The first, Aromia japonica PD96CŃ, 1968 is a junior synonym of Chloridolum thaliodes B6I:H, The second, Leontium multiplicatum P>8, 1946 is reconfirmed as a synonym of Leontium viride T=DBHDC, 1864 as was suggested by N6@6C: (1976 b). In addition, Chelidonium testaceicorne P>8, 1946 is a synonym of Hybunca chrysogramma barombana S8=B>9I, 1922, an African species. The abbreviations used in the depositories of the type specimens are as follows: MNHNP Muséum National d Histoire Naturelle de Paris; SFNF Senckenberg Forschungsinstitut und Naturmuseum, Frankfurt am Main. Chloridolum (Chloridolum) thaliodes B6I:H, 1884 (Figs. 1 2, 12 13) Chloridolum thaliodes B6I:H, 1884, 226; type localit(ies): Sapporo, Kobe. Chloridolum (Parachloridolum) thaliodes: PA6K>AHIH=>@DK, 1934, 69. Chloridolum (Chloridolum) thaliodes: KJH6L6 & T6@6@JL6, 1984, 299. Aromia japonica PD96CŃ, 1968, 302, pl. 7, fig. 47; type area: Japan. Syn. nov. Material examined. Chloridolum thaliodes B6I:H: Lectotype, male, Japan, ex coll. W. B6I:H (in MNHNP). Aromia japonica PD96CŃ: Holotype, female, Japan, coll. E. W=>II: (in SFNF). Notes. Aromia japonica PD96CŃ, 1968, is no doubt a junior synonym of Chloridolum thaliodes B6I:H, 1884, since the structure of pronotum and antennae, and the length of hind femora completely correspond between these two taxa. The holotype of A. japonica has an unusual dark purplish body unlike the normal form of C. thaliodes which almost always has the dark green body. N6@6C: (1976 a) already suggested a possibility that A. japonica may be a

According to K. A@>I6 (pers. comm.), he had examined an individual variation similar to the holotype of A. japonica.

MNHNP). Leontium multiplicatum P>8: Holotype, male, Sounkyo, Hokk., coll. Pic (in MNHNP). Notes. P>8 (1946 b) literally suggested that Leontium multiplicatum is a close relative of L. tenuatum B6I:H, 1873 in his original description (L. tenuatum is also a synonym of L. viride T=DBHDC, 1864). After a comparative examination between the holotypes of L. multiplicatum and L. viride, it was revealed that both the taxa are synonymous. Their synonymies are already suggested by N6@6C: (1976 b) based on his direct examination of the holotype of L. multiplicatum. He also wrote that the holotype of L. multiplicatum was determined as a forma of L. viride by V>AA>:GH and H6N6H=>. However, we did not recognize such a label in the lectotype.

Chelidonium testaceicorne P>8: Holotype, male, Kioto, Japon (in MNHNP). Notes. According to the original description by P>8 (1946 a), Chelidonium testaceicorne was found at Kioto of Japan without other detailed data. Nonetheless, the holotype of this species no doubt belongs to Hybunca chrysogramma barombana described from Gabon and Camerun, West Africa (S8=B>9I, 1922). It is not first time that we found mistakes for identification or original

Chelidonium testaceicorne should be regarded as a junior synonym of Hybunca chrysogramma barombana, and excluded from the Oriental fauna.
