摘要

摘要描述了巴西帕尔州和马托格罗索州里约热内卢Xingu盆地的一新种Poptella。新种与所有同类的区别在于，它在尾端花序梗周围有更多的鳞片(15-18比13-14)。此外，该物种可以很容易地与P. brevispina, P. longgipinnis和P. fuscata区分，因为背鳍上的分支射线数量较少(9比10-11)。新分类群的发现是近5年来发现的第三种。

A new Poptella from the rio Xingu basin, Brazil (Characiformes: Characidae)

Abstract A new species of Poptella is described from the rio Xingu basin, Pará and Mato Grosso states, Brazil. The new species is distinguished from all congeners by having a greater number of scales around the caudal peduncle (15–18 vs. 13–14). Furthermore, this species can be easily distinguished from P. brevispina, P. longipinnis, and P. fuscata by the lower number of branched rays in the dorsal fin (9 vs. 10–11). The description of new taxon represents the third species of the genus Poptella described in the last five years.

期刊介绍： Neotropical Ichthyology is the official journal of the Sociedade Brasileira de Ictiologia (SBI). It is an international peer-reviewed Open Access periodical that publishes original articles and reviews exclusively on Neotropical freshwater and marine fishes and constitutes an International Forum to disclose and discuss results of original research on the diversity of marine, estuarine and freshwater Neotropical fishes. -Frequency: Four issues per year published only online since 2020, using the ‘rolling pass’ system, which posts articles online immediately as soon as they are ready for publication. A searchable and citable Digital Object Identifier (DOI) is assigned to each article immediately after online publication, with no need to await the issue’s closing. -Areas of interest: Biology, Biochemistry and Physiology, Ecology, Ethology, Genetics and Molecular Biology, Systematics. -Peer review process: The Editor-in-Chief screens each manuscript submitted to Neotropical Ichthyology to verify whether it is within the journal’s scope and policy, presents original research and follows the journal’s guidelines. After passing through the initial screening, articles are assigned to a Section Editor, who then assigns an Associate Editor to start the single blind review process.
