Keywords:biodiversity, species and subspecies, skipper butterfly, genitalia, Anastrus obliqua
AbstractAnastrus isidro n. sp. is described from Panama and Costa Rica. This new species is most similar to its South American counterpart A. obliqua, but differs from it by wing coloration, pattern and many prominent characters of male and female genitalia. A lectotype for Antigonus obliqua Plötz, 1884 is designated to ensure nomenclatural stability.
