Cytological identities of Simulium tuberosum and S. vulgare (Diptera: Simuliidae), with notes on other Palearctic members of the S. tuberosum species-group
Abstract Cytological studies of Simulium tuberosum s.l. from the type locality in northern Finland demonstrate the presence of three reproductively isolated species. One of these species, here designated FGIO, has not previously been described cytologically, whereas the remaining two cytospecies, AB...
