Abstract
In 1927, Collin named British specimens returned by Mik as "W. rhynchops var." Wiedemannia rhynchops ssp. Insularis . He stated that the British specimens differed from Continental ones in the shape of the upright finger-like process of the gonostyle (sensu Ulrich, 1972). Having studied some hundred Central European specimens, and having compared them to specimens from the British Isles, the author states that there is a wide variability in the shape of the gonostyle, and evidently no feature to distinguish a British subspecies of W. rhynchops .
