Telmatrechus is an extinct heteropteran genus in the water strider family Gerridae which is solely known from Early Eocene sediments exposed in western North America. the genus contains three described species, the type species Telmatrechus parallelus, plus Telmatrechus defunctus, and Telmatrechus stali. The genus has been considered closest to remigis-group species of the living Aquarius, which are all confined to the Nearctic.

Distribution

Fossils of Telmatrechus are found in early Eocene, Ypresian age lacustrine deposits in two areas of Western North America. The type species, Telmatrechus parallelus was first described from Fossil Lake, and later found in Lake Uinta, both of which are included in the Green River formation.
