Description/
Field Marks:
Tortricidia is in need of revision.
Similar Species:
  • 4654 Tortricidia flexuosa - Marc Epstein (pers. comm., 2018) advises that we are currently unable to separate many of what we call Tortricidia pallida and Tortricidia flexuosa based on the larva, adult (including genitalia), and DNA. Furthermore, illustrations of the type of pallida, which is no longer extant, appears to be what we often refer to as flexuosa. At present, flexuosa represent all the 'morphs' (those that are heavily marked on the FW down to very little, but more on the yellowish side of things) and pallida represent the more pale, almost pinkish tan ones that have either a faint band or nothing on the FW.

Synonymy:
  • pallida (Herrich-Schäffer, 1854) (Limacodes) MISAPPL. - MONA 1983: 4653
      Type locality: North America.
  • flavula (Herrich-Schäffer, 1854) (Limacodes)
  • Taxonomic Notes: Tortricidia pallida (Herrich-Schäffer, 1854) and Tortricidia flexuosa (Grote, 1880), another name with lower priority which may refer to the same taxonomic entity, were appended as "T. pallida of authors" and "T. flexuosa of authors" respectively in Pohl & Nanz (eds.) (2023) to reflect the uncertainty in the application of those names. Both names refer to entities described from NA yet neither were additionally listed separately as originally proposed, effectively delisting those original combinations. Also, both were listed with valid synonyms, but ICZN Article 23 seems to suggest that the name with priority should be the valid name. Pending further clarification, we revert to the previous usage.
