Larva and Host Plants: Viburnum Similar Species: 51a0552.1 Olethreutes betulana Pinned specimens of related species. (Hint: select View by Region on the related species page.) Synonymy: trepidulum (Heinrich, 1926) (Exartema) REV. STAT.; TL: Hampton, N.H. diallacta (Meyrick, 1932) (Argyroploce); TL: Maine. nitidana of Zeller, 1875; (not Clemens, 1860) (Exartema) misid. zelleriana (Fernald, 1882) (Eccopis) nom. nud. - MONA 1983: 2783; Lectotype: Maine. Note: Lectotype designated by Miller (1970). Taxonomic Notes: Olethreutes trepidulum (Heinrich, 1926) was formerly treated in Brown (2005) as a synonymy of O. diallacta (Meyrick, 1932). (Diallacta is a replacement name for zelleriana (Fernald, 1882), preoccupied in Argyroploce by zelleriana (Erschoff, 1874) (now placed in Clepsis)). Trepidulum was subsequently treated as a full species distinct from diallacta by Gilligan & Brown (in Pohl & Nanz (eds.) (2023)). In an apparent oversight, the authors regarded zelleriana as a nomen nudum (no type or description). Fernald described zelleriana for the specimen misidentified in Zeller (1875) as nitidana (Clemens, 1860). That specimen was later designated as the lectotype of zelleriana by Miller. McDunnough (1955) confirmed that zelleriana and trepidulum (host plant = Viburnum (McDunnough 1942)) referred to the same species. However, as noted by McDunnough, Fernald erroneously described the host plant of zelleriana as Betula based on other specimens. Following the interpretations of McDunnough (1955) and Miller (1970), Powell (in Hodges et al. (1983)) listed the names zelleriana for the species which feeds on Viburnum (omitting the replacement name diallacta - oversight?) and betulana (Heinrich, 1926) (originally a manuscript name by Kearfott validated by (Heinrich, 1926) (McDunnough 1955)) for the species which feeds on Betula). MPG follows Powell but corrects the name zelleriana to trepidulum, the name which would appear to be the oldest valid synonym.
