Abstract

Abstract An expedition crowdfunded by aquarists to a region of the Brazilian state of Pará drained by the Tapajós and Xingu river basins resulted in the capture of five species of Corydoras from the rio Jamanxim basin, a tributary to the rio Tapajós, of which three could be confirmed as new and described herein. The new species can be promptly diagnosed from their congeners by the combination of features related to color pattern and osteology. Considering the gathered information on color patterns and morphology plus field observations, the new species are considered to compose two distinct Müllerian mimicry rings, with two of them forming a mimetic pair, while the third one forms a pair with a fourth non-identified species captured in the same expedition. An identification key to the species of Corydoras from the rio Tapajós basin is also provided.

巴西里约热内卢Tapajós盆地发现三种新的Corydoras (siluriforma: Callichthyidae)，并对Corydoras sp. CW111进行了评述

一项由水族爱好者众筹的考察活动在巴西par州的Tapajós和Xingu河流域的一个地区进行，结果在里约热内卢Tapajós的支流里约热内卢Jamanxim盆地捕获了5种Corydoras，其中3种可以确认为新物种，本文将对其进行描述。结合颜色图案和骨学特征，可以从其同系物中迅速诊断出新种。考虑到收集到的颜色模式和形态信息以及实地观察，新物种被认为是由两个不同的勒勒氏模仿环组成的，其中两个形成一个模仿对，而第三个与同一次探险中捕获的第四个未识别的物种形成一对。并给出了里约热内卢Tapajós盆地鸦尾藻种类的鉴定钥匙。

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.
