Abstract

Abstract A new species of Rhyacoglanis from the upper rio Tocantins basin is described based on morphological and molecular data. The new species differs from the congeners by its color pattern, caudal fin shape, hypural bones fusion pattern, pectoral-fin spine shape, and barcode sequence of cytochrome oxidase subunit I (COI). In this study, two putative monophyletic groups of Rhyacoglanis are proposed based on morphology, one consisting of species with a short post-cleithral process and caudal fin with rounded lobes, Rhyacoglanis epiblepsis and R. rapppydanielae, and the other with a longer post-cleithral process and caudal fin with pointed lobes, R. annulatus, R. paranensis, R. pulcher, R. seminiger, and the new species described herein.

文章标题Tocantins盆地上半段柳蝇属新种(志留虫目:拟蝗科)

摘要根据形态和分子资料描述了Tocantins盆地上部里约热内卢的一新种Rhyacoglanis。新种在颜色图案、尾鳍形状、后脑膜骨融合图案、胸鳍脊柱形状以及细胞色素氧化酶亚基I (COI)的条形码序列等方面与同系物有所不同。本研究基于形态学提出了两个单系类群，其中一个类群由喉后突短、尾鳍圆叶的Rhyacoglanis epiblepsis和R. rapppydanielae组成，另一个类群由喉后突长、尾鳍尖叶的R. annulatus、R. paranensis、R. pulcher、R. seminiger以及本文描述的新种组成。

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.
