Remarks Terra typica:Russian Karelia and Finland (‘jag har funnit den vid Vigsjön [=‘Lac.Wig’(Silfverberg,1988)] (63°50’) och Svir i Ryska Karelen, i Kihtelysvaara, Eno och Nurmis socknar i norra Karelen äfvensom vid Jyväskylä och Helsingfors’). In the original description, Sahlberg supposed that Thomson’ s (1857) record of S. aemulus Erichson, 1839 (see S. ( N. ) nitens above) for Sweden should be referred to S. confusus , but this seems to be doubtful since the species description is quite adequate to S . nitens Stephens, 1833, for which aemulus is in fact a synonym. Poppius (1909a) reported the species from the middle reaches of the Lena River: ‘An der mittleren Lena an lehmigen Ufern, ein Exemplar bei Jakutsk, 1.VII!, ein anderes auf einer Insel nördlich von Önkyr-yrjä, 8.VII!.’ (the East Siberian latipennis specimens, identified by Poppius as confusus and found by Puthz (1972c) in ZMH, were collected at other localities and cannot be correlated to the material cited in Poppius 1909a). Jakobson (1909) summarised the range as follows: ‘ Sweden <the record is most likely based on Thomson’s misidentification of confusus as aemulus : see above>; Lapponia, Finland, Olonets Government’. Munster (1921) provided some distributional data for northernmost Norway: ‘Kaafjord i Alten, Sirma i Tanen samt Neiden, Langfjordbunden, Vaggatim og Graense-Jakobselv i Syd-Varanger!’; L. Benick (1924), a bit later, cited the only female from SE Siberia (‘Tschita’); Palm (1961) confirmed N Swedish records of this species (Norrbotten, Jämtland); Haberman (1983) provided three mapped localities from Estonia; a pair of specimens (1 &male;, 1 &female;) have been published recently from the Moscow Area (Semenov, 2004). The terra typica of S . protensicollis Krása, 1941, which was placed in synonymy with confusus (Puthz, 1973c, 1998): ‘Simbirsk, Rossia m.[ed]’. The new material above confirms that S. confusus is rather widespread in the Northern Palaearctic, but the species has proved to be rare and sporadic in its distribution. It is essential that all the Siberian records known to me are represented by females only. I expect the range to have a relict pattern. : Published as part of Ryvkin, Alexandr B., 2012, New species and records of Stenus (Nestus) of the canaliculatus group, with the erection of a new species group (Insecta: Coleoptera: Staphylinidae: Steninae), pp. 1-62 in European Journal of Taxonomy 13 on pages 41-43, DOI: 10.5852/ejt.2012.13, http://zenodo.org/record/3857775 : {"references": ["Sahlberg J.
