Taxonomic remarks. The recently published revision of the genus Gnathonarium Karsch 1881 by Tu & Li (2004), provided with splendid and highly detailed illustrations, clearly shows that G. cambridgei Schenkel 1963, known from China, represents a junior synonym of Gnathonarium taczanowskii (O. Pickard­Cambridge 1873) syn. n. The latter species was originally described from the Lake Baikal region (Pickard­Cambridge 1873), and currently known to be widespread in Asia from the Urals in the West to Cisokhotia, Kamchatka, Sakhalin etc. in the East; also recorded in Mongolia and throughout South Siberia. In the Nearctic, recorded only from Alaska (Tanasevitch 2006).
