Abstract

Nealyda grandipinella Bennett and Hayden, new species, is described from Big Pine Key, Florida, USA. Photographs of the adult and of male and female genitalia are provided for N. grandipinella and its congeners within the state of Florida. Nealyda Dietz (Lepidoptera: Gelechiidae) is provisionally transferred from Anomologinae to Apatetrinae based on characters of the genitalia. The homology and terminology of the processes arising from the vinculum of gelechiid genitalia are explored. The potential host plant of the new species is discussed, along with other undescribed species of Nealyda.
