Beitrag zur Kenntnis der Bergwaldhummel Alpigenobombus wurfleini (Radoszkowski, 1859) (Hymenoptera, Apidae, Bombinae) Von W. F. Reinig t und P. Rasmont Abstract Alpigenobombus wurfleini (Radoszkowski, 1859) belongs to a bumblebee-genus widespread throughout the Pa-learctic Tertiary mountains. It is morphologically near A. kashmirensis (Friese, 1909) from Himalaya. It can be found in most of the West-Palearctic mountains where it Hves in forest biotopes without tresspassing the tree-line. It does not exist in the British Isles nor in the South Iberian and Itahan peninsulae. European Russia and West-Ana-toha. A group of Hght coloured subspecies includes the following taxa: ssp. wurfleini from Caucasus and NW-Anato-Ha, ssp. uralicus (Pittioni, 1938) from Ural, ssp. pyrenaicus (Vogt, 1909) from Pyrenees and Cantabrian mountains. A group of dark subspecies (mastrucatus auct.) inhabits Scandinavia, the Massif Central, Alps, Tatras, Balkans and Carpathian Mountains. — The males are everywhere light coloured and show only slight colour variations. This suggests that dark coloration is a recent genetic acquisition. Alpine and Fennoscandian populations are widely separated from one another but share certainly a common geo-graphic origin. Phenotypic and ethologic characters of the Scandinavian population provide evidence to assign it a subspecific rank. Their priority name is ssp. brevigena (Thomson, 1870). In the Balkan mountains two populations can be found that are morphologically very close but, nevertheless well isolated. They constitute together the ssp. apfelbecki Reinig nov. The Carpathic population must be treated also as a good subspecies: knechteli Reinig nov. The population from Ligurian Apennines shows a coloration near from the ssp. apfelbecki but their Status cannot be clarified because of a shortage of material. The populations of the Massif Central, the Alps and Tatra Mountains belong all to the ssp. mastrucatus (Gerst-aecker, 1869) but show slight colour differences which can be explained by their Isolation in separated fauna refuges during the last iceage: — the population of the southern side of the Alps has probably spread from a fauna refuge in the Po piain; — the French Alps population could be coming from a refuge in the Durance, Isere, Rhone and Saone Valleys; — lighter Massif Central population is likely coming from a refuge located in the Garonne basin, it could have been hybridized there with the ssp. pyrenaicus. This would explain its slightly lighter coloration; — population of Jura, Switzerland and Vorarlberg can be coming from a refuge in the high Rhein Valley; — population of East-Alps (North of Tauern), South-Germany, Bohemian, Tatra and North-Carpathian Moun-tains as, perhaps, North-German and Fennoscandian populations could have a common origin m an arboreal fauna refuge located in Lower-Austria in Wien area and in South-Slovenia. The common behaviour of Alpigenobombus wurfleini making holes in flower corollas is shortly discussed. Vorwort Bei seinem Tod am 7.6.1980 hinterließ Dr. W. F. Reinig (Nürtingen-Hardt) zahlreiche unvollendete Manu-skripte. Einige davon sind so vollständig, daß ihrer Veröffentlichung nichts im Wege steht. Die hier vorgelegte Ar-beit ist durch die Zusammenlegung zweier Artikel über den Alpigenobombus wurfleini zustandegekommen, wovon der eine Teil die Fauna der Alpenhummeln behandelte, während der andere Teil die Hummeln Oberösterreichs 37
