Summary:
The entomofauna of Cocos Island, Costa Rica, includes nearly 100 species of Lepidoptera, among which are 13 species of Tortricidae, most of which are endemic. One of these, Coelostathma insularis, new species, is described and illustrated. The new species is most similar to C. binotata (Walsingham) from Mexico among described species. The genus Coelostathma Clemens is redescribed, and a lectotype is designated for C. binotata. The shared possession of abdominal dorsal pits in Coelostathma Clemens, Amorbia Clemens, and Aesicopa Zeller suggests a close phylogenetic relationship among these genera within Sparganothini; the variably modified subdorsal pits in Sparganopseustis Powell and Lambert may or may not be homologous with those of the other genera.
