摘要

摘要报道了巴西新古河Scobinancistrus属一新种。它可以通过颜色图案和非排他特征的组合与同类区分开来:整个身体在深色背景上覆盖着大片的黄色间隔斑点(相对于S. pariolispos和S. aureatus在浅色或深色背景上的小圆形和密集的斑点);背鳍和尾鳍上缺乏橙色到黄色/橙色的远端带(金色棘鱼有)，背鳍在压迫时不能到达脂肪鳍支撑板(相对于金色棘鱼和金色棘鱼到达脂肪鳍板)。新物种只在新谷河中部的一部分地区被发现，从因建造贝罗蒙特大坝而受到强烈人为影响的Volta Grande do新谷河到伊里里河与新谷河汇合处附近。讨论了该物种面临的威胁及其保护现状。

A new species of armored catfish of the genus Scobinancistrus (Loricariidae: Hypostominae) from the Xingu River basin, Brazil

Abstract A new species of Scobinancistrus from the Xingu River, Brazil, is described. It can be distinguished from its congeners by color pattern and a combination of non-exclusive characters: overall body covered by large yellow spaced blotches over a dark background (vs. small round and densely packed spots over light or dark background in S. pariolispos and S. aureatus); lack of orange to yellow/orange distal band on dorsal and caudal fins (vs. presence in S. aureatus), dorsal fin not reaching adipose-fin supporting plate when adpressed (vs. reaching the adipose-fin plate in S. pariolispos and S. aureatus). The new species is only known from a portion of the middle Xingu River, ranging from the Volta Grande do Xingu, an area under a strong anthropic impact due to the construction of the Belo Monte dam, to near the Iriri River confluence with the Xingu River. Aspects concerning the species’ threats and its conservation status are discussed.

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.
