Abstract

A new crambid moth, Haimbachia spartina Solis and Canepuccia, new species is described from Argentina and images of the adults and their genitalia are provided. The larvae were discovered feeding on species of saltmarsh cordgrass or Spartina Schreb. (Spartinaceae). This is the first description and illustration of a Haimbachia Dyar larva. Twelve species have been described in the Western Hemisphere, but only Haimbachia maroniella Dyar and Heinrich, has been previously described from South America. The new species is compared to H. maroniella and images are provided of its type specimen, labels, and male genitalia.
