The Neotropical genus Sericostola Meyrick, 1927, and its type-species, S. rhodanopa Meyrick, 1927, from Colombia, are given a modern description and reassigned from Yponomeutidae to Glyphipterigidae. Nearest relatives appear to be in the genus Cotaena Walker or Myrsila Walker. A new species from Costa Rica, S. semibrunnea, is described and assigned to Sericostola.
