Claremontia confusa = Monophadnoides confusa sensu Benson
What was originally called confusa became renamed to brevicornis (Liston et al. 2014), but then Liston et al. (2022) had the name revert to confusa whilst simultaneously renaming puncticeps as brevicornis. The species appears to occur northwards to central Scotland (Musgrove, 2023).
The head is black and glossy but with small tubercles. The second antennal segment is noticeably wider than long. The thorax is also black and the mesopleura are sparsely clothes with tubercles. The abdomen is also black. The legs are variable being mostly black. The wings are strongly infuscated.
Claremontia confusa larvae feed on strawberry plants.
