Info
This key covers three of the four known northern European
Protarchus
species. One species,
P. grandis
, is only known from its holotype and is potentially a synonym of
P. testatorius
, from which it is supposedly differentiated by a slightly more elongate first tergite.
Missing species
Protarchus grandis
