, have some other important characters in common, e.g., carinate sternites and paramere shape of the males, although the female of the latter species displays a very peculiar habitus. While the species within each of these two clades show an allopatric distribution in general, two species of the first and the second clade, respectively, were occasionally collected in the same streams, thus demonstrating that even within the same species group there are sympatric, or even syntopic, species.
