Check List of the Geometridae (Lepidoptera) of the Former USSR

The aim of this checklist is to summarize the author's personal results obtained from faunistic investigations, from the study of literature sources and collections of Geometridae in state museums as well as from discussions with his colleagues during a 30-year period. The study area has been delimited not by physical but political barriers. Since the Soviet Union has come to an end, together with one epoch of history, it is the time to sum up research data for the next generation of faunists to set off and proceed further.
