Interpretive Summary: Many species of pyraloid moths are pests of tropical timber trees worldwide. The moths of the Chysauginae contain larvae that are biologically diverse and are found, for example, as seed predators, external feeders of orchids, and sloth fecal feeders. A chrysaugine species new to science from Costa Rica was discovered boring into a timber tree, and its biology studied. The adults and immatures of the new specie are described, illustrated, and placed in a classification so that they can be readily identified by quarantine identifiers. This information will be useful to both action agency identifiers and to pest managers and other scientists.

Technical Abstract: Cromarcha stroudagnesia Solis, new species, from the dry-forested Pacific coastal lowlands of northwestern to central Costa Rica and from Jalisco in Mexico in described. The biology and immature stages are also described. The larvae bore inside the shoots of new rainy season growth of Tabebuia ochracea (Bignoniaceae) saplings. Tabecuia ochracea is known as corteza amarilla and is a tropical timber tree in Costa Rica.
