Interpretive Summary: The United States has seen an increase in snout moth invasive species, such as the Mexican rice borer, an invasive stalk-boring pest in southern United States. We describe a new species closely related to the Mexican rice borer, whose caterpillar feeds on sugarcane in the panela-growing area of Colombia. We provide photographs of the immatures, adults, and the damage it causes. This information will help sugarcane growers, biological control workers, and quarantine personnel to identify this species.
Technical Abstract: A new crambid, Eoreuma insuastii, sp. n., is described from Colombia. The larvae were discovered feeding on sugarcane grown for brown sugar loaf or “panela.” This new species is similar to E. donzella Schaus that was described from Brazil. We describe and illustrate the adults and their genitalia. We provide images of larvae and pupae, and damage to sugarcane for field identification. We provide images of the type specimens, their labels, and genitalia of all three known described species, E. donzella, Eoreuma paranella (Schaus), Eoreuma morbidellus (Dyar) from South America. The new species is compared to Eoreuma loftini (Dyar), a common pest species of graminaceous crops in Mexico and the United States.
