Abstract: Species of Telmatogeton and the closely related genus Paraclunio
generally live on the rocky shores of the intertidal zone. Species of Telmatogeton
have evolved from the marine environment into torrential freshwater
streams of the Hawaiian Islands . An analysis of the banding sequences of the
polytene chromosomes of species of Telmatogeton and Paraclunio from the
Hawaiian Islands and North America suggests that there were at least two
separate invasions from the marine to freshwater environments. One is through
the marine species T. japonicus to an undescribed freshwater species found on
east Maui . The other invasion requires a marine hypothetical species that gave
rise to the Hawaiian freshwater species T. abnormis and T. torrenticola.
