摘要

摘要:麻蝇属是麻蝇科的一个属，目前已有20个有效种。这些物种大多栖息在亚马逊盆地的临时水池中，只有一种在巴拉圭盆地上部被发现。这个属的一个新成员从Río马德拉河上部的排水在这里描述。这种新物种的雄性与所有同类的不同之处在于，它们的身体上有一种由倾斜的、有时像chevv的、不规则的红色和浅蓝色双点组成的颜色图案;暗黄色到金色的胸鳍没有明显的斑点;在尾鳍的腹侧部分有条纹图案，有一条非常窄的黑色边缘线，断断续续甚至没有。本文讨论了Moema属内物种群的存在，以及该物种在Ríos mamor河和itsamuez / guapor河流域的地理分布和分类学特征，以及该新物种的种内攻击行为和两栖生活方式。

A new species of the seasonal killifish genus Moema (Cyprinodontiformes: Rivulidae) from the Piraí watershed in the Southwest Amazon basin

Abstract Moema, a genus of the Rivulidae family, currently comprises 20 valid species. Most of these species inhabit temporary pools in the Amazon basin and only one species is found in the upper Paraguay basin. A new member of this genus from the upper Río Madeira drainage is here described. Males of the new species differ from all congeners by the combination of a color pattern consisting of oblique, sometimes chevron-like, irregular rows of red and light blue double-dots on body; dark yellowish to golden pectoral fins with no visible markings; and a stripe pattern on the ventral section of caudal fin with a very narrow black marginal line, intermittent or even absent. The existence of infrageneric species groups within Moema, the geographic distribution and taxonomic aspects of the species present in the Ríos Mamoré and Iténez/Guaporé rivers drainages, and the observation of intraspecific aggression between males and amphibious lifestyle in the new species 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.
