Taxonomy and phenetic relationships of Electrogena affinis (Eaton, 1883) (Ephemeroptera : Heptageniidae)
Published online by Cambridge University Press: 01 February 2009
Abstract
Electrogena affinis (Eaton, 1883) is redescribed in all developmental stages. Larvae were analysed, in comparison with other congeneric european species, by a standard set of diagnostic characters which, in previous works, proved to be very useful in the taxonomy of Electrogena. The status of E. fascioculata (Sowa, 1974) is discussed and the synonymy E. fascioculata = E. affinis is stated. Finally, phenetic relationships between E. affinis and some other related european species are represented by cluster analysis, on the basis of quantitative characters of larvae.
