A new Stamnodes from the southwestern United States (Lepidoptera, Geometridae, Larentiinae).

ABSTRACT

Stamnodes fergusoni sp. nov. occurs from extreme southeastern Arizona through southern New Mexico east into western Texas, USA. Identity of the new species can be reliably determined by external features, genitalic characters, and COI haplotypes. Larvae are believed to be specialists on Salvia pinguifolia and S. ballotiflora. The adult and larval stages and male and female genitalia are illustrated, available DNA barcode data that support the recognition of the new Stamnodes are reviewed, and its life history briefly characterized.
