Hagnagora unnia

Hagnagora unnia is a species of moth of the family Geometridae. It is found in Costa Rica.

Males are usually smaller but otherwise are indistinguishable from those of Hagnagora elianne. They may be distinguished from Hagnagora anicata by the swollen distal half of the uncus (as opposed to gently tapered) and the absence of a moderately large, upcurved spine at the end of the costa. Females may be distinguished from those of H. elianne by their shorter, less complex signum. The female of H. anicata is undescribed. Specimens from higher altitudes are larger as are most H. elianne. Specimens from lower altitudes are smaller as are most H. unnia. Although size alone cannot always be used to distinguish the species, it is often an excellent indicator, particularly where both species occur together.
