Tobias’ Caddisfly was described in 1977 on the basis of specimens that had been collected in 1938.

The species apparently lived in the vicinity of the Main- and Rhine Rivers, and its aquatic larvae (which, however, are completely unknown) developed in these rivers. The Main as well as the Rhine were very polluted during the 20th century, which led to the local extinction of many fish species – and obviously also to the global extinction of this certain aquatic insect.
