Abstract
Hydroporus tatianae sp. n. is described from north-western Siberia, and Hydroporus kabakovi sp. n. from the Chitinskaya Oblast' in south-eastern Siberia and from Mongolia. Both new species are similar to the Nearctic H. larsoni Nilsson, 1984, the Holarctic H. fuscipennis Schaum, 1868, and the Palaearctic H. pseudopubescens Zimmermann, 1919, which so far has been considered a member of the H. striola -group. All these five members of the H. planus -group have the tip of the penis provided with one or two projections, a character which has never been reported in the genus Hydroporus so far. Lectotypes of the following taxa are designated: Hydroporus puberulus Mannerheim, 1853, Hydroporus punctatissimus Poppius, 1905, and Hydroporus pseudopubescens Zimmermann, 1919. Hydroporus fuscipennis is recorded for the first time from Kazakhstan and Turkmenistan.
