Journal ArticleTwo new species of the hyperdiverse geometrid moth genus Eois (Lepidoptera, Geometridae, Larentiinae) from Ecuador, with descriptions of early stagesDoan, Lydia M; Miller, James S; Brown, John W; Forister, Matthew L; Dyer, Lee A<p>The hyperdiverse geometrid genus<italic>Eois</italic>Hübner, estimated to encompass more than 1,000 species, is among the most species-rich genera in all of Lepidoptera. While the genus has attracted considerable attention from ecologists and evolutionary biologists in recent decades, limited progress has been made on its alpha taxonomy. This contribution focuses on the Olivacea clade, whose monophyly has been recognized previously through molecular analyses. We attempt to define the clade from a morphological perspective and recognize the following species based on morphology and genomic data:<italic>E. olivacea</italic>(Felder & Rogenhofer);<italic>E. pseudolivacea</italic>Doan,<bold>sp. nov.</bold>;<italic>E. auruda</italic>(Dognin),<bold>stat. rev.</bold>;<italic>E. beebei</italic>(Fletcher, 1952),<bold>stat. rev.</bold>;<italic>E. boliviensis</italic>(Dognin),<bold>stat. rev.</bold>; and<italic>E. parumsimii</italic>Doan,<bold>sp. nov.</bold>Descriptions and illustrations of the immature stages of<italic>E. pseudolivacea</italic>reared from<italic>Piper</italic>(Piperaceae) in Ecuador are provided.</p>Zookeys2024-02-2110537302ZooKeys1192111 to 1401313-2989https://doi.org/10.3897/zookeys.1192.1112752114793National Science Foundation
