Abstract

Abstract A new species of Tatia is described from rio Tapajós, upstream of the rapids of São Luiz do Tapajós, Pará State, Brazil. The new species is identified and diagnosed from its congeners through morphological characteristics such as the absence of an adipose fin, which is shared with T. akroa and T. britskii; the composition of the cranial roof elements; the color pattern consisting of dorsolateral dark dots formed by both dermal and epidermal pigments; as well as several morphometric measures. The new species is a Centromochlinae fish that feeds on insects on the surface of the water at night and it is probably endemic to rio Tapajós basin.

巴西里约热内卢Tapajós Tatia浮木鲶鱼新种(siluriforma: Auchenipteridae)

摘要在巴西帕尔州 o Luiz do Tapajós急流上游的里约热内卢Tapajós描述了一新种。该新种是通过其同系物的形态学特征进行鉴定和诊断的，如缺少与T. akroa和T. britskii共有的脂肪鳍;颅顶元素的组成;由真皮和表皮色素形成的背外侧黑点组成的颜色图案;以及一些形态测量方法。这一新物种是一种以夜间水面上的昆虫为食的Centromochlinae鱼，它可能是里约热内卢Tapajós盆地的特有物种。

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.
