Three new species of Hagnagora Druce, 1885 (Lepidoptera, Geometridae, Larentiinae) from Ecuador and Costa Rica and a concise revision of the genus Author Brehm, Gunnar text ZooKeys 2015 537 131 156 http://dx.doi.org/10.3897/zookeys.537.6090 journal article http://dx.doi.org/10.3897/zookeys.537.6090 1313-2970-537-131 EA901A84CB134889A77C07E89EDA172E Taxon classification Animalia Lepidoptera Geometridae Hagnagora luteoradiata (Thierry-Mieg, 1892) stat. rev. Figs 33-35 Type locality. Costa Rica. Remarks. Hagnagora luteoradiata was put in synonymy with Hagnagora ephestris by Parsons et al. (1999). However, luteoradiata specimens consistently do not show any yellow blotches on the hindwing as observed in ephestris and clustimena . Barcoded specimens from Costa Rica (Fig. 34) and Ecuador (Fig. 35) are genetically very similar (distance only ca. 1.1%) and, together with the highly similar appearance, are therefore regarded as conspecific. The ephestris type specimen from Bogota , Colombia, falls within the geographical range of the luteoradiata specimens, but shows a different wing pattern, i.e. a prominent yellow blotch on the hindwing and a different shape of the blotch of the forewing. The taxon luteoradiata is therefore revived from synonymy. Distribution. Costa Rica to Ecuador. Observed elevational range in Ecuador 1800-2890 m and 560-1480 m in Costa Rica. Diagnosis. The most prominent difference is the absence of any yellow blotches on the hindwing that are present both in ephestris and discordata . The transversal yellow band on the forewing is broader than in discordata , and has a different shape than in ephestris .
