Remarks: Poeciloptilia arundiniella Herrich-Schäffer, 1855: 301 , 308 was considered a misspelling by Stainton (1858a: 306); that interpretation was also followed by Wocke (1871: 326). Following IZCN (1999, Art. 24.2), Stainton (1858) is the first reviser. Following him, the name arundiniella Herrich-Schäffer, 1855 is a misspell- ing of E. arundinella Zeller, 1850 . Due to homonymy with Elachista arundinella Duponchel, 1843 , neither of these names is available. The name arundinis Herrich-Schäffer, 1855: pl. 124, fig. 1029 is not a binomial name and thus unavailable. Morris (1870: 214) validates the name gregsonella . He refers the name to Doubleday’s gregsonella . Doubleday (1859: 34) lists gregsoni as ‘synonym’ of gregsonella . Elachista gregsoni Stainton, 1855: 70 is, however, senior to E. gregsonella .
