A new genus and species of Spilomelinae (Lepidoptera, Pyralidae) from the Galapagos Islands, Ecuador

Resumen

A new genus and species of Spilomelinae (Lepidoptera, Pyralidae) from the Galapagos Islands, Ecuador. -Cheverella galapagensis Landry, gen. n. and sp. n. is described as an endmie of the Galapagos Islands, Ecuador. Based on a combination of two apomorphies (reduced uncus and prsence of setose pads on anterodorsal extensions of the maie valva medially) this taxon is possibly related to Choristostigma Warren, now placed in the Hydriris group of Munroe (1995), but Cheverella lacks the setose projection at base of the valve's costa prsent in Choristostigma. The female has a clearly circumscribed corpus bursae with a short, spine-like signum. Cheverella also shares a few characters with members of the Siga group. The larva is a borer in stems of the endmie Tournefortia pubescens Hook./ (Boraginaceae).
