Cercyon (s. str.) inquinatus Wollaston, 1854

(Figs. 31–32)

Cercyon inquinatus Wollaston, 1854: 103 . For complete synonymy see Hansen (1999) and Short & Hebauer (2006). Cercyon rhombicus Jia, 1995 in Jia et al. 1995: 128. Synonymized by Ryndevich (2004b).

Type material examined. Cercyon rhombicus: Holotype: 1 3 (SYSU), “Guangzhou, Shipai, Pig farm, 25.vii.1985, leg. Wu Wu [transcribed from Chinese] // Holotype, Cercyon rhombicus, det. F.L. Jia”. Paratypes: 1 Ƥ (SYSU), same data as holotype, but “Allotype, Cercyon rhombicus, det. F.L. Jia”; 13 exs. (SYSU), same data as holotype but “ Paratype, Cercyon rhombicus, det. F.L. Jia”; 2 exs. (SYSU), “Fengkai, Heishiding mount, 5.vii.1986, leg. Wu Wu // Paratype, Cercyon rhombicus, det. F.L. Jia”.

Taxonomic notes. Ryndevich (2004b) proposed the synonymy of Cercyon rhombicus with C. inquinatus based on the original description only, without the examination of type specimens of the former species. During this study, we have reexamined the type specimens and compared them with the specimens from Europe and North America deposited in NMPC. As the types of C. rhombicus correspond well with these specimens in all diagnostic characters as well as in the morphology of male genitalia (see also Smetana 1979, Ryndevich 2004b), we can confirm the synonymy proposed by Ryndevich (2004b).

Distribution. Widely distributed throughout various temperate to tropical regions, recorded from Austria, Azores, Canary Islands, Czech Republic, Croatia, Italy, Japan, USA, Brazil as well as from several islands (Madeira, Mascarene Islands, Java, New Caledonia) (Hansen 1999, 2004; Ryndevich 2004b).
