摘要

Harttia属Loricariinae亚科，目前已发现27种，分布于圭亚那盾地、亚马逊河流域和巴西东南部。新种与同系物的区别在于:管板存在;腹部板无;四边形肛前板;雄鱼在第一胸鳍上和在头部的外侧区域，靠近管板上具长而明显的齿状突;有背鳍小刺。本文给出了里约热内卢s o Francisco盆地的物种识别键，并将该新分类单元与该属所有其他物种进行了比较。

A new species of Harttia from the rio São Francisco basin (Siluriformes: Loricariidae)

Abstract The genus Harttia belongs to the subfamily Loricariinae and has to date 27 described species, distributed in the drainages of Guiana Shield, Amazon and southeastern Brazil. The new species is distinguished from its congeners by the combination of: canal plate present; abdominal plates absent; trapezoid preanal plates; males with elongated and conspicuous odontodes on the first pectoral-fin ray and on the lateral region of the head, close to the canal plate; and dorsal-fin spinelet present. An identification key for the species of the rio São Francisco basin and a comparison between the new taxon and all other species of the genus are presented.

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.
