摘要
摘要根据形态和分子资料,描述了巴西东南部伊瓜帕拉苏、mag、Saracuruna、瓜皮帕拉苏、Macacu、maca和Paraíba do Sul河流域的一新种Rineloricaria。该新种是根据以下特征在同系物中诊断出来的:胸带腹面大部分没有板;鼻尖椭圆形裸露区,后伸至感觉管眶下支最前端孔;背鳍小刺存在;有光滑龙骨的枕上板和前背板;背鳍下面有五组侧板;中间和中腹侧的一系列板,龙骨发育良好。这一新物种与生活在巴西里约热内卢州马山脉流域的同族物种的区别在于,它们的胸带腹侧表面和腹部部分被板块覆盖(相比之下,黑脉线虫、斯坦达内里线虫和扎瓦兹基线虫的胸带和腹部完全被板块覆盖)。这个新物种和其他来自帕拉纳、乌拉圭和其他巴西沿海河流流域的物种一样,腹部表面没有板块。
A new species of Rineloricaria (Siluriformes: Loricariidae) from coastal drainages of Rio de Janeiro, southeastern Brazil
Abstract A new species of Rineloricaria is described from the Iguaçu, Magé, Saracuruna, Guapiaçu, Macacu, Macaé, and Paraíba do Sul River basins in southeastern Brazil based on morphological and molecular data. The new species is diagnosed among congeners by the combination of the following characters: absence of plates in most of the ventral surface of pectoral girdle; snout tip with elliptical naked area reaching posteriorly the anteriormost pore of the infraorbital ramus of sensory canal; dorsal-fin spinelet present; supraoccipital and predorsal plates with smooth keels; five series of lateral plates below the dorsal fin; median and mid-ventral series of plates with well-developed keels. The new species is distinguished from congeners that inhabit the rivers draining the Serra do Mar in Rio de Janeiro state by the partial plate coverage of the ventral surface of the pectoral girdle and the abdomen (vs. pectoral girdle and abdomen completely covered by plates in Rineloricaria nigricauda, R. steindachneri, and R. zawadzkii). The new species shares the absence of plates on the abdominal surface with other species from the Paraná, Uruguay, and other Brazilian coastal river basins.
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.
