This dataset contains the digitized treatments in Plazi based on the original journal article Martins, Fernanda O., Langeani, Francisco (2016): Redescription of Hisonotus notatus Eigenmann & Eigenmann, 1889 (Loricariidae: Hypoptopomatinae), the type species of the genus, and description of a new species from coastal drainages of southeastern Brazil. Neotropical Ichthyology 14 (2), No. e 150100: 1-18, DOI: 10.1590/1982-0224-20150100, URL: https://www.mendeley.com/catalogue/a63a17a8-edfc-3e93-964e-a4d7fed0bb8d/Our analyses showed that the type series of Hisonotus notatus, type species of the genus, is mixed, composed by two different species. Based on that, we redescribe H. notatus with the designation of a lectotype, restricting the species to rio São João drainage and other small coastal drainages running to the Baía de Guanabara and to the Baía de Sepetiba in Rio de Janeiro State. We also describe a new species of Hisonotus from drainages of the rio Paraíba do Sul, Lagoa Feia, rio Macaé, and coastal rivers of Espírito Santo State, from rio Itabapoana to rio Doce basin. These two species are sister-taxa and can be distinguished by the number of plates in the mid-dorsal series.Nossas análises mostraram que a série-tipo de Hisonotus notatus, espécie-tipo do gênero, é mista, composta por duas diferentes espécies. Baseado nisso, nós redescrevemos H. notatus com a designação de um lectótipo, restringindo a espécie à drenagem do rio São João e outras pequenas drenagens que correm para a Baía de Guanabara e para a Baía de Sepetiba no estado do Rio de Janeiro. Também descrevemos uma nova espécie de Hisonotus das drenagens do rio Paraíba do Sul, Lagoa Feia, rio Macaé e rios costeiros do estado do Espírito Santo, do rio Itabapoana à bacia do rio Doce. Essas duas espécies são táxons irmãos e podem ser distinguidas pelo número de placas na série médio-dorsal.

本数据集收录了Plazi平台的数字化分类学处理文献,源自原始期刊论文:Martins, Fernanda O.、Langeani, Francisco(2016)所著《模式属代表物种Hisonotus notatus Eigenmann & Eigenmann, 1889(甲鲶科(Loricariidae)下口鲶亚科(Hypoptopomatinae))的重新描述,以及巴西东南部沿海水系一新物种的记述》。该文刊载于《新热带鱼类学(Neotropical Ichthyology)》第14卷第2期,文章编号为e 150100,页码范围1至18,DOI:10.1590/1982-0224-20150100,资源链接:https://www.mendeley.com/catalogue/a63a17a8-edfc-3e93-964e-a4d7fed0bb8d/。研究团队经分析确认,该属模式物种Hisonotus notatus的模式标本系列混杂有两个不同物种。基于此结果,我们通过指定选模标本(lectotype)对H. notatus进行重新描述,并将该物种的分布范围限定为圣若昂河(rio São João)水系,以及巴西里约热内卢州境内注入瓜纳巴拉湾(Baía de Guanabara)与塞佩蒂巴湾(Baía de Sepetiba)的小型沿海水系。此外,我们还记述了一新的Hisonotus物种,其分布涵盖南帕拉伊巴河(rio Paraíba do Sul)水系、费亚湖(Lagoa Feia)、马卡埃河(rio Macaé),以及圣埃斯皮里图州境内从伊塔巴波阿纳河(rio Itabapoana)至多西河(rio Doce)流域的沿海河流。上述两个物种为姊妹分类群(sister-taxa),可通过背中列骨板的数量加以区分。
