First verified record of Hydroporus nigellus Mannerheim, 1853 from China

Hydroporus nigellus Mannerheim, 1853 belongs to the nigellus -group of the genus and is distributed in large parts of Europe and Asia (see Nilsson 2011). It was recorded from " China ( Mongolia)" by Feng (1932: 25) and from "Peiping" by Wu (1937: 209) (both under the name Hydroporus obscuripes (Motschulsky, 1860)) . Nilsson (1995: 53) suspected that Feng did not mean the "Chinese part of Mongolia " (Nei Mongol, "Inner Mongolia "), but the territory of what today is named " Mongolia " (" Outer Mongolia "). In addition Nilsson (1995: 53) declared Wu's record as "doubtful". We have no new information about these records, but can report that we have studied correctly determined specimens with the following collecting data: 17.7.1974, China, SE Qinghai, Yushu county, Batang village [estimated to be 33.0N 97.0E; not Batang in Sichuan!], 4200 m (the specimens were incorrectly identified as Hydroporus saghaliensis Takizawa, 1933 by H. Zeng in her PhD thesis and have, thus, the respective determination labels) (46 exs); 12.07.1995, NW Sichuan, ca. 40 km SSE Sertar, road Luhuo–Sertar, ca. 31.9N 100.6E, altitude ca. 2800 m, Rejsek leg. (3 exs); 27.6.2005, SE Qinghai, 35 km WSW Jigzhi, ca. 33.22N 101.07E, altitude ca. 4400 m, Kaláb leg. (12 exs); all specimens in SYSU and CHF, further specimens in CPM and CJS. All three localities are situated in a relatively small area of about 400 km diameter; some altitude data seem to be "very roughly estimated".
