- Аннотация: Using 60 Palaearctic species of the leafhopper genus Macropsis as an example, the contribution of sympatric and allopatric speciation to the origin of herbivorous insect biodiversity was studied. According to the previously reconstructed evolutionary scenarios, in the temperate zone of the Palaearctic Region the genus Macropsis probably dispersed from east to west and formed 10 natural groups, with species within each group being similar both in morphological traits and in host specialization. The hypothetical speciation modes for each group can be largely inferred from geography. If related species replace each other in diff erent zoogeographic regions, they are likely to have arisen as the result of allopatric speciation. If the species show overlapping distributions and live on the same host plant, they must have originated in allopatry and become secondarily sympatric due to subsequent dispersal. Finally, if related species have strongly overlapping ranges and populate similar habitats but diff er in host specializations, this may indicate their origin as the result of sympatric speciation due to host plant shifts. For 31 species (51.7%), allopatric speciation seems to be the most likely or even the only possible scenario, whereas for 20 species (33.3%), the hypothesis of sympatric speciation is either convincingly substantiated or at least quite feasible. The origins of the remaining 9 species (15%) remain unknown. Therefore, sympatric speciation is not a rare phenomenon in Macropsis, but it certainly does not predominate over the allopatric mode. Thus, even within the same genus of herbivorous insects, speciation can occur in diff erent ways: in the allopatric mode, when a host plant shift is possible but not essential, and in the sympatric mode, when divergence is triggered by the host shift. Cases of intraspecifi c diff erentiation, which can be considered as initial stages of speciation, are also discussed. These are allopatric color forms associated with the same host plant, allopatric color forms associated with diff erent plants and, fi nally, forms living on diff erent sympatric or allopatric hosts but showing no diff erence in coloration. It is shown that divergence is not always caused by transition to a new host plant even in specialized herbivores.
