Morris’s species is almost certainly conspecific with  E. subalbidellain the absence of other similar species in England. The taxonomy of  E. subalbidellaand similar taxa is uncertain in the Alps. Until the identity of  P. subochrellaHerrich-Schäffercan be verified, its current status as a synonym is maintained. 2274831239 [662,1292,1736,1763] Germany Weimar 125 126 1 2274831245 [376,585,1808,1835] NHMUK United Kingdom England 125 126 1 1 holotype 2274831253 [442,762,1952,1979] NHMUK Coll.
