Calopteryx is a
genus of large
damselflies belonging to the family
Calopterygidae. The colourful males often have coloured wings whereas the more muted females usually have clear wings although some develop male (
androchrome) wing characteristics. In both
sexes, there is no
pterostigma.[1]
Nomenclature
It was only in 1890, many years after Leach named the genus Calopyteryx, that it was widely recognized that Leach's name was a junior synonym of the Fabrician genus Agrion, established 40 years prior. The controversy surrounding which genus name has nomenclatural priority has never been formally resolved; the
ICZN mandates that Fabricius' name has priority, but the majority of the world's
odonate researchers maintain the use of Calopteryx.[2]
