Die Nephrotoma-Verbreitung in der Welt (Diptera, Tipulidae) Naturalis

Almost all species of the southern hemisphere occupy strongly restricted areas in mountain forests, but the holarctic species are much more widely distributed. Within the range of the deciduous forests a number of centres can be recognized which are particularly rich in species. An exception is formed by a species-rich focus ranging from the Altai through the Baikal area, where taiga and sparsely wooded steppes intermingle. Contrary to the other centres hardly any endemics occur in this focus. The area is interpreted as a centre where species from north and south,...
