Abstract
Thirteen European and four North American species of Siphlonuridae and Ameletidae were investigated biochemically using starch gel electrophoresis. Twenty enzyme loci were examined in 28 populations. In comparison with Siphlonurus aestivalis, S. croaticus exhibits different electromorphs for two enzymes, and thus maintains the species status. Two common electromorphs and high identity values with the other species of the S. aestivalis-group allow one to place S. flavidus in the S. aestivalis-group. For three enzyme loci the Ameletus species share common electromorphs, different from those of Metreletus balcanicus. This fact allows one to consider Metreletus as a valid genus. Because of the few common enzyme electromorphs and the low identity values, the Ameletus-Metreletus-complex should be separated from the Siphlonurus-Parameletus-complex and included in the Family Ameletidae.
