Cercyon (Clinocercyon) lineolatus ( Motschulsky, 1863)

( Figs. 28–30 )

Trichopoda lineolata Motschulsky, 1863: 444 . Transferred to Cercyon by Gemminger & Harold (1868). Cercyon nigrostriatus Wu et Pu, 1995 in Jia et al. 1995: 127. syn. nov.

Type material examined. Cercyon nigrostriatus : Holotype: 1 3 ( SYSU), “Xinyi, 6.v.1986, leg. Wu Wu // Holotype, Cercyon nigrostriatus sp. nov. Pu et Wu, det. Wu Wu”. Paratypes: 1 Ƥ ( SYSU), “Xinyi, 6.v.1986, leg. Wu Wu // Allotype, Cercyon nigrostriatus sp. nov. Pu et Wu, det. Wu Wu”; 1 ex. ( SYSU), “Guangzhou, Shipai, Pig farm, 25.vii.1985, leg. Wu Wu // Paratype, Cercyon nigrostriatus , det. W. Wu”; 2 exs. ( SYSU), “Guangzhou, Shipai, Cattle farm, 25.vii. 1985, leg. Wu Wu // Paratype, Cercyon nigrostriatus , det. W. Wu”; 4 exs. ( SYSU), “Xinyi, 8.v.1986, leg. Wu Wu // Paratype, Cercyon nigrostriatus , det. W. Wu”.

Additional material examined. CHINA: Yunnan: 2 exs., Mengla Nature Reserve, 4-5.viii.2007, leg. Jiahui Li ( SYSU). Taiwan: 1 3, Pingdong, Sizhongchi ( HUMS).

Taxonomic notes. The type specimens of C. nigrostriatus correspond well with the specimens of C. lineolatus from different parts of the Oriental Region and from the United Arab Emirates (all deposited in NMPC) in all diagnostic characters. We therefore propose C. nigrostriatus as a junior subjective synonym of C. lineolatus .

Distribution. Recently recorded for the first time from China ( Jia et al. 2010). In China recorded from Yunnan, Guangdong and Taiwan. Outside China widely distributed in tropical and subtropical regions from Arabian Peninsula throughout the Oriental Region ( India, Indonesia, Philippines, Sri Lanka, Vietnam), also recorded from Mascarene Islands ( Hansen 1999, Fikáček et al. 2010).
