Lilioceris balyi Chûjô, 1962 ( Fig.1 )

Lilioceris balyi Chûjô, 1962: 1 ( Japan) .

Material examined. ♂ ( BMNH), Holotype / C. subpolita , Type, Baly / Hiogo / Baly collection / Lilioceris (s. str.) balyi Chûjô , det M. CHUJO, 1962.

Remarks. This species was once recorded by Baly (1873) as var. B of Crioceris subpolita Motschulsky, 1861 . Kimoto (1961) recognized it as an undescribed species. Then, Chûjô (1962) named it as Lilioceris balyi and provided a detailed description. However, based on the observation of the holotype by the third author ( LHB) and Ms. Yingqi Liu ( BMNH), an error was found in Chûjô’s original description. In the holotype, the mesoventral process is slightly widened, tuberculate, horizontally connected with metaventrite, rather than "neither dilated apically nor bending backwardly" in Chûjô (1962). In addition, the right antennomeres 3–11 was actually missing ( Fig. 5 ) when we checked, while it’s complete in Chûjô (1962: 1). This species is similar to L. subpolita , but differs from the latter by having punctures of elytral striae extending to the elytral apex (punctures absent on the apical half in L. subpolita ).

Distribution ( Fig. 30 ). Japan.

Host plant and habitat. Unknown.
