Onycholabis sinensis nakanei Kasahara, 1986:76 ( Japan) .

Specimens Examined. Total 6 specimens: JAPAN : 1 male and 1 female ( NSM), ‘‘ Yadorigizawa , Kanagawa Pref., 9-VI-1982, S. Kasahara leg.’’/‘‘ PARATYPE, Onycholabis sinensis nakanei Kasahara, 1986 ’’ ; 2 males and 2 females, ‘‘Yadorigi-zawa, Tanzawa, Kanagawa Pref. 14- VII-82, S. Morita leg.’’/‘‘ Onycholabis sinensis nakanei Kasahara, Det. S. Morita, 2004 ’’ .

Description. Kasahara (1986:76–80) gave a detailed description. We add the following: pro- and metepisterna impunctate, PW/HW ¼ 1.02 or 1.04 (two paratypes).

Remarks. Adults of this taxon, without setae at pronotal basal angles, with pronotum only slightly wider than long (PW/PL ¼ 1.1–1.2), and with relatively small eyes, are clearly different from those of O. sinensis Bates ; and we recognize this taxon as a distinct species. It is closely related to O. melitopus , but adults can be distinguished from those of the latter by the impunctate pro- and metepisterna, elytral apex at sutural angle rounded, and sixth visible sternum with four marginal setae in males and eight in females.

Distribution. Known only from central Honshu, Japan.
