ARTICLE: Rediscovery of Hemigrammus unilineatus in Ecuador after more than three decades

We are pleased to share with you this interesting study on a small characid, Hemigrammus unilineatus that has been rediscovered in Yasuní National Park, eastern Ecuador, where it has not been reported since 1987. We present a detailed taxonomic description, including measurements and photographs, as well as a distribution map of this specie in Ecuador. Based on our new evidence, we confirm the presence of H. unilineatus in the Ecuadorian Amazon.

This great contribution was possible thanks to a collaboration between the Instituto Nacional de Biodiversidad (INABIO), Red de Ictiología del Ecuador and Universidad San Francisco de Quito (USFQ).
