  Type species:

   Hydrophilus spinosus Steven, 1808 by monotypy ((Hope, F.W., 1838) actually cites Berosus orientalis Hope as the type species, but this is a nomen nudum and since the only other species mentioned by Hope was Berosus spinosus (Steven) this becomes the type species, see (Hansen, M., 1987) [221]).
