Remarks: Herrich-Schäffer’s name Poeciloptilia rufocinerella is to be considered a misspelling of rufocinerea, the spelling used by Herrich-Schäffer (1855) in both the key (p. 302) and in parentheses “(- nerea),” as well as in the entry of rufocinerea (p. 312). Morris (1870: 228) validated the name rufocinerella . However, he followed Haworth, 1828: 535 in regards to the identity of the species. E. rufocinerella is thus an unjustified emendation.
