Orthocladius pubitarsis Zett. sensu Lundström (1915: 9) not Chironomus pubitarsis Zetterstedt, 1838: 821 View in CoL .

Material examined. RUSSIA: New Siberian Islands, south coast of Kotelnyj Island, 2 ɗ, 23–24 vi 1903, A. W. Koltschak & P. W. Olenin.

The specimens key to P. (P.) barbimanus (Edwards) in Wülker (1956) and Langton (1980). However, Zelentsov & Makarchenko (1988) erected the species P. sokolovae differing in among other features a slightly higher antennal ratio and higher numbers of setae The present specimens have numbers of dorsocentrals, scutellars, setae on tergite IX, and length of the anal point as in P. sokolovae , while the number of clypeal setae (13–22) are within the variation of P. barbimanus (11–21, while 28–35 in P. sokolovae ). The antennal ratio is about 2.5–3.1 in the present specimens, 3.0– 3.05 in P. sokolovae , 2.4–2.8 in P. barbimanus according to Zelentsov & Makarchenko (1988). In all other details the specimens examined here conform to P. sokolovae .

The genus Psectrocladius , even if several partial revisions exist, is in need of a complete revision. Unpublished results suggest that the spring generation often is so different from the autumn generation of the same species that they easily could be regarded as different species. This applies both to pupae and imagines. Complicating this is that a species may have two generations a year in one locality, a one­year generation with a different appearance in another.
