Additional material examined. CHINA: Guangdong: 19 exs., Xinyi 6-9.v.1986 ( SYSU). JIANGXI: 1 ex., Jiulianshan mount, 14.vii.2008, leg. Fenglong Jia ( SYSU). TAIWAN: 1 Ƥ, Taipei ( HUMS). VIETNAM: 1 ex., Hoa-Binh. leg. A. de. Cooman (identified as Cercyon vicinalis ) ( SYSU). INDONESIA: 12 exs., Sumbawa ( HUMS).

Taxonomic notes. The type specimens of C. linearis correspond well with the Oriental specimens of C. subsolanus in all external characters and the morphology of male genitalia (see Ryndevich 2008). Therefore, we propose here C. linearis as a junior subjective synonym of C. subsolanus .
