This new family was established when a new genus and species,
Aspidytes niobe, was found
and morphological and DNA characters indicated that it had no living relatives.
This relic group resembles Jurassic-Cretaceous fossil species and occurs in mountain
rivers of the Western Cape in South Africa. Aspidytidae beetles are specifically
adapted for a life in rivers, in
crevices and on
wet rock faces behind algae with just a trickling film of water running
