Electrogena affinis (Eaton, 1883) is redescribed in all developmental stage
s. Larvae were analysed, in comparison with other congeneric european speci
es, by a standard set of diagnostic characters which, in previous works, pr
oved to be very useful in the taxonomy of Electrogena. The status of E. fas
cioculata (Sowa, 1974) is discussed and the synonymy E. fascioculata = E. a
ffinis is stated. Finally, phenetic relationships between E. affinis and so
me other related european species are represented by cluster analysis, on t
he basis of quantitative characters of larvae.
