Remarks. Having been originally described from Irkutsk, L. dimidiatipenne is also recorded for N Anatolia ( Coiffait 1982), the Donets Basin, NW Caucasus ( Tichomirova 1976), and the Crimea ( Gusarov 1989). Tichomirova (1976) believed the range of the species had a disjunction from the Caucasus to Eastern Siberia. I do not know any reliable specimens from territories westwards of Ural; all the specimens supposed to be L. dimidiatipenne were in fact either L. tichomirovae Coiffait, 1981 or L. bernhaueri Koch, 1937 ; the new data cited above widen the siberian range of L. dimidiatipenne largely westwards. I do not know this species also from the Far East; the mention by Tichomirova (1973) seems to be based on misidentification and has not been cited in the later paper ( Tichomirova 1976). The citations of this record by the subsequent compilers (Kurcheva 1977; Shavrin 2007), without providing new material, are likely based on the named mistake of the previous author.
