Hyphessobrycon chiribiquete new species

   Etymology: The specific epithet refers to the type locality of this species, in the Parque Nacional Natural Serranía de Chiribiquete, and territory of the ancient indigenous Carijonas. It is to be treated as a noun in apposition. Chiribiquete National Natural Park is located in the northwest sector of the Colombian Amazon in the departments of Caquetá and Guaviare. The nearest large town is San Juan de Guaviare. It is the largest national park in Colombia and the largest tropical rainforest national park in the world. It was established on 21 September 1989 and has been expanded twice, first in August 2013 and then in July 2018. The park occupies about 43,000 km2 (17,000 sq mi) and includes the Serranía de Chiribiquete highlands and surrounding lowlands, which are covered by rainforest and savannas.
