Redescription of Hyphessobrycon cachimbensis (Characiformes: Characidae) with the description of a new congener from the Serra do Cachimbo, Brazil

This dataset contains the digitized treatments in Plazi based on the original journal article Marinho, Manoela Maria Ferreira, Dagosta, Fernando Cesar Paiva (2024): Redescription of Hyphessobrycon cachimbensis (Characiformes: Characidae) with the description of a new congener from the Serra do Cachimbo, Brazil. Neotropical Ichthyology (e 230127) 22 (2): 1-20, DOI: 10.1590/1982-0224-2023-0127, URL: dx.doi.org/10.1590/1982-0224-2023-0127 The Serra do Cachimbo is a highland area at the southeastern portion of the Amazon Forest drained by the headwaters of tributaries of rios Xingu and Tapajós.

It is known as an area of high level of endemism of fish, low species diversity, and very few taxa with broad distribution in the other parts of the Amazon. Despite its biogeographical importance, there are still many poorly sampled areas. Four expeditions to the region yielded in the rediscovery of a poorly known, endemic species, Hyphessobrycon cachimbensis, and the discovery of a similar, allopatric undescribed congener, frequently misidentified as H. cachimbensis.
