Abstract
We studied the genetic structure of Dinocras cephalotes (Curtis, 1827) in Central Italy, by means of starch-gel electrophoresis. Eleven populations from three different rivers (Aniene, Nera, Velino) were analysed. 21 enzymes were screened, yelding data for 27 presumptive loci. Genetic interpopulation distances (D; Nei, 1978) were relatively low, ranging from D=0.000 to D=0.052. These results show little differentiation among the populations and agree to some extent with the data coming from other genetic studies of Plecoptera. Nevertheless genetic distances among some contiguous subpopulations of each river seem fairly high for taxa spatially contiguous (D max=0.052).
