I have the species in my regular collection also from RUSSIA: TVER (= KALININ) AREA (Dubniki ca. 16 km NNE Udomlya), MOSCOW AREA (Pushkinskiy District, Gorenki; Istrinskiy District, nr. Pavlovskaya Sloboda), KOSTROMA AREA (Manturovskiy District, nr. Shilovo)[see Ryvkin 1984], SAMARA (= KUYBYSHEV) AREA (left side of Chapayevka River , 20 km below Chapayevsk), MOLDAVIA (Kagul District: Roshu) .

Remarks. The type species of the genus, widely distributed in temperate Palaearctic, known from ‘C & N Europe, Middle Asia, Siberia’ ( Tichomirova 1973), but seems to be absent in Mediterranean subtropics ( Coiffait 1982: ‘semble manquer dans les parties le plus chaudes de la zone méditerranéenne’). L. elongatum has been reported in Siberia for Altai ( Gebler 1830, 1848; Babenko, 1981), Tyumen Area, Omsk Area, Novosibirsk Area (J. Sahlberg 1880), Krasnoyarsk Territory (J. Sahlberg 1880; Mäklin 1881), Irkutsk Area ( Poppius 1909; Shavrin 1998, 2001), Buryatia ( Shavrin 1998), Yakutia ( Poppius 1909). Mäklin (l.c.) considered Gebler’s Altai records of L. elongatum to be in fact L. boreale Hochhuth, 1851 , but the material provided herein removes all doubts in the presense of the former in that region. In the same way, all the available specimens, identified earlier as L. elongatum , from Shavrin’s collection prove to belong to other species, but the good new series cited above makes it possible to confirm occurrence of L. elongatum in the Irkutsk Area. The data provided refute the assertion concerning transpalaearctic distribution of the species ( Boháč 1986) since no records are known eastwards off the line Baikal to the Aldan River mouth.

Basing on both my data ( Ryvkin 1984) and studies by Tichomirova (1982 etc.), the species can be regarded as an inhabitant of the earlier stages of eutrophic and, to a lesser extent, mesotrophic hydroseries in plant succession systems.
