Cosmopterix attenuatella (Walker, 1864)

Polillas de cosmet, Cosmet moth

This species can be separated readily from its three Galapagos congeners by the united band formed by the shining spots at the base of the forewing fascia. On average, this is the smallest of the four Galapagos Cosmopterix species; the wingspan of the males (n=45) varies from 7.0 to 9.0 mm, and the wingspan of the females (n=24) is between 7.5 to 9.5 mm. The moths also appear generally darker than the other three species. The male genitalia (figs 15, 16) are characterized by the slender and apically pointed aedeagus. In the female genitalia (fig. 28), the ostium bursae is in a narrow sclerotized tube extended and enlarged anteroventrally, the corpus bursae is large and without signum, and the ductus bursaeconnects with the corpus bur > at its anterior end (Landry, 2001).
