The Protoperlina are a group of insects recorded from the late Carboniferous to the early Cretaceous. The monophyly of the group is uncertain; Storozhenko (2002) defined it on the basis of characters of the forewing, but the type species Protoperla westwoodi is represented by a hindwing only (Béthoux et al. 2005). At least some Protoperlina were probably detritivores.
Characters (from Storozhenko 2002): Fore wing CuA and its branches situated in posterior wing half; proximal branch of fore wing CuA forming series of marginal veinlets across posterior wing margin.
