Gelechiid Moths from the Islands of Peter the Great Gulf (Lepidoptera: Gelechiidae): Preliminary Faunistic Analysis


Margarita G. Ponomarenko

The comparative faunistic analysis of species diversity of family Gelechiidae in Islands of Peter the Great Gulf and in neighboring continental territories is made. The island fauna turned out depleted because of small size of islands, limited landscape diversity and impossibility of active moth migration due to their weak flying abilities. However the concentration of species diversity in islands is almost two orders of magnitude larger than that in continental part. The proportion of Gelechiid groups with certain type of geographic range in islands is similar to that in continental part, that is treated by recent their isolation. The fauna of every examined island is disharmonic, representing by some species from every genus and includes small number of common species that is interpreted by continual species extinction and an insignificant random drift from mainland.
