The (: Pyralidae) of the Galapagos Islands, Ecuador, with keys to the Neotropical species of Guenée

Bernard Landry & Lazaro Roque-Albelo

The subfamily Glaphyriinae (Lepidoptera, Pyralidae) is recorded from the Galapagos Islands, Ecuador, for the first time on the basis of two species of Hellula Guenée, 1854: (Walker, 1859) and H. galapagensis Landry sp. n. The new species is described and both species are illustrated. Two illustrated keys based on external characters and genitalia to the Neotropical species of Hellula are provided. Hellula phidilealis was reared on Cleome viscosa L. (Capparidaceae) in the Galapagos. Hellula kempae Munroe is reported from Cuba for the first time.

Resumen: La subfamilia Glaphyriinae (Lepidoptera, Pyralidae) es registrada por primera vez para las Islas Galapagos, Ecuador basada en dos especies de Hellula Guenée, 1854: Hellula phidilealis (Walker, 1859) y H. galapagensis Landry sp. n. La nueva especie es descrita y ambas especies son ilustradas. Dos claves ilustradas, basadas en los caracteres externos y en la genitalia, son proveidas para la identificación de las especies Neotropicales de Hellula. Hellula phidilealis fue criada en Cleome viscosa L. (Capparidaceae) en las Galapagos. Hellula kempae Munroe es registrada por primera vez para Cuba. Bernard Landry*, Muséum d’histoire naturelle, C.
