Claremontia brevicornis = Monophadnoides puncticeps sensu Benson
What was originally called puncticeps became renamed as brevicornis (Liston et al. 2022), a name that was previously being used for what is now called confusa (Musgrove, 2023). Historic records should be treated with contempt. The species appears to occur widely to northern Scotland.
The head is black with conspicuous tubercles which are usually denser on the lower inner orbits. The thorax and the abdomen are also black. The legs usually have white tibiae though these may be infuscated.
Claremontia brevicornis larvae feed on Salad Burnet and Creeping Cinquefoil.
