(Original designation).' ,8.lefebvrei Lepeletier, 1836, holotype ? MNP, iS,however, now revised to ^8. pomorum (Panzer),1802-05, by Tkalcu (1969) and this species belongsto the subgenus Rftodobombus Dalla Torre, 1880.In his meagre description, Skorikov (1914a) wrotethat he had gathered what he called all the endemicforms of '8. lefebvrei Lep. ( - B. mastrucatusauct.)' occurring in the mountain fauna of Eurasiainto one genus or subgenus, Alpigenobombus. AsSkorikov obviously meant B. mastrucatus, thistaxon is retained as type-species for Alpigeno'bombus in order to serve stability and uniformityof nomenclature.According to Tkalcu (1969), B. mastrucatus is,however, a European subspecies of B. wurfleiniRadoszkowski, 1859. Tkalcu examined the holotypeof the latter but did not trace the type seriesof .8. mastrucatus IZB, which unfortunately bythen was at my disposal. The series consists of29?,22??, 14 66 of which a male, selected as lectotypeby ffieo is labelled as follows: (1) Ober-Bayern, Kreuth Gerstaecker S (printed) ; (2) mastrucatusGerst. * d oper. Kreuth (handwritten?original); (3) red label marked parutype; (4) B.mastrucatus Gerst. d lectotype design. A. Laken1965. The specimen was chosen because of theasterisk in the text of the second label as 'DieseSternchen sind in unserer Sammlung zuverldssi-Studies on Scandinavian <strong>Bumble</strong> <strong>Bees</strong> 25gere Indikatoren ftir Typen als die roten Etiketten'(Konigsmann in litt. 1966). I have not seenthe holotype (a male) of -8. wurfleini, and havetherefore not been able to compare this specimenwith the type material of ,8. mastrucatus to confirmthe conspecificity of the taxa. Radoszkowski(1884, p. 66) emphasizes the structural similarityin the males of -8. wurfleini and B. mastrucatus,but maintains a specific difference in the females.However, he indicates that B. mastrucatus mightbe a variant of ,8. wurfleini - B. alpigenus Morawitz.Their conspecificity has been recognized inthe past (Morawitz 1881 , p. 71 ; Handlirsch 1888;Friese & Wagner 1909; Kruseman 1960; Reinig1965, p. ll7; etc.), but the priority of B. wurfleinihas been ignored and the species treated as B.mastrucatus. The nominate form of B. wurfleinihas a colouring of the coat completely differentfrom that of ,8. mastrucatus and the taxa have,moreover, an allopatric distribution. The statementof Tkalcu (1969) is no doubt correct, i.e.B. mastrucatus Gerstaecker - B. wurfleini mastrucatusGerstaecker.B. wurfleini mastrucatus is the only Scandinavianrepresentative of the subgenus.BOMBUS ( ALPIGENOBOMBUS )W U RFLEI N I RADOSZKOWSKIBombus wurfleini Radoszkowski, 1859, p. 482No. 4, holotype d ZIK, type area Caucasus(Tkalcu 1969).(Bombus levebvrei auctt. nec Lepeletier, 1836;Strand 1901 ; Brinck & Wingstrand 1949.
