Circanota: a new genus of Sparganothini from the Neotropics,and its two new species (Lepidoptera,Tortricidae)

Circanota, new genus, and its two new species, Circanotaundulatasp. n. (type species), from Costa Rica and Panama, and Circanotasimplexsp. n., from Panama and Ecuador, are described and illustrated. Although superficially similar to some species of Platynota Clemens, 1860, Circanota appears to be more closely related to members of a putative clade within Sparganothini defined by a slender crescent-shaped signum in the corpus bursae of the female genitalia. The most conspicuous autapomorphy for Circanota is the strongly undulate costa of the male and female forewing. Barcode sequence data (i.e., cytochrome oxidase I) from Circanotaundulata (n = 12) form a tight cluster with exceedingly limited genetic divergence (less than 0.1%); specimens of Circanotasimplex have not been sequenced. In neighbor-joining trees based on COI, Circanota is portrayed nearest Sparganothoides, which is consistent with morphological evidence.
