摘要

摘要在巴西par州中部里约热内卢Tapajós右岸支流里约热内卢jamanem流域里约热内卢Aruri Grande中描述了一新种Ammoglanis。新种是通过形态学特征来识别和定义的，如颜色图案，由8或9个横向深色条纹组成，沿背有规则地间隔;骨骼形态;前颌牙齿，脊椎骨和背鳍和胸鳍射线的数目;颅囟的存在和两个小的，手指状的乳头在颏嵴前。新物种可能是里约热内卢Tapajós盆地特有的另一个例子。

Description of a new species of miniature catfish of the genus Ammoglanis (Siluriformes: Trichomycteridae) from rio Tapajós basin, Brazil

Abstract A new species of Ammoglanis is described from the rio Aruri Grande, rio Jamanxim drainage, a right bank tributary to the middle rio Tapajós, Pará State, Brazil. The new species is identified and defined through morphological characters such as color pattern, consisting of eight or nine transverse dark bars regularly spaced along the dorsum; skeletal morphology; numbers of premaxillary teeth, vertebrae, and dorsal- and pectoral-fin rays; presence of cranial fontanel and two small, finger-like papillae on chin anterior to the gular apex. The new species probably is an additional example of endemism in the rio Tapajós basin.

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.
