Abstract

To update the knowledge of the ichthyofauna of the Tumbes River basin, we provide a list of species. We report 47 species of fishes, grouped into 23 families and 11 orders. Characiformes was the most diverse order with 12 species (25.5% of the total richness), followed by Carangiformes with eight species (17%). In our study, two species are newly reported from this river basin: Pseudophallus starksii (Jordan & Culver, 1895) and Evorthodus minutus Meek & Hildebrand 1928. According to salinity tolerance, the ichthyofauna is composed of 20 primary, 14 secondary, and 13 peripheral species. Despite having the highest diversity of fish on the Peruvian Pacific slope, the Tumbes river basin is one of the most polluted coastal drainages. This study compiles information on the ichthyofauna of the entire basin, increases the known diversity of freshwater fish from trans-Andean drainages in Peru, and can be used in the management and conservation of the Tumbes River.

秘鲁北部跨安第斯山脉的通贝斯河流域的鱼类区系

为了更新对通贝斯河流域鱼类区系的认识，我们提供了一份物种列表。我们报告了47种鱼类，隶属于23科11目。群落特征最丰富的目有12种(占总丰富度的25.5%)，其次是兽形目，有8种(占总丰富度的17%)。在我们的研究中，该流域新报道了两个物种:Pseudophallus starksii (Jordan & Culver, 1895)和Evorthodus minutus Meek & Hildebrand 1928。根据耐盐性，鱼系可分为20种初级鱼类、14种次级鱼类和13种外围鱼类。尽管在秘鲁太平洋的斜坡上鱼类的多样性是最高的，但通贝斯河流域是污染最严重的沿海流域之一。这项研究汇编了整个盆地的鱼类区系信息，增加了秘鲁跨安第斯流域淡水鱼的已知多样性，并可用于通贝斯河的管理和保护。

期刊介绍： Check List is a peer-reviewed online journal, devoted to publishing biodiversity data related to species’ geographic distribution. Thus, our primary mission if to fill the so-called Wallacean shortfall (Lomolino 2004) and to improve our knowledge of how life is distributed on the planet in order to better preserve it. These data are essential for studies on biogeography and provide a baseline for the conservation of biodiversity. The first step to undertaking effective conservation action is to maintain records of the distribution of species. Therefore, the journal was created from the need publish basic data on species distribution of any taxon in a timely and open manner, which are often neglected by traditional journals. Check List is a bimonthly peer-reviewed online journal, and will consider for publication: -distribution summaries of a supraspecific taxon in a broad geographic area (e.g., hemisphere, country, biome), as a review of the distribution of a taxon in the given area. -annotated list of species, of a given taxon in a strict geographic area, with comments and illustrations on the identifications, based on original data. -notes on the geographic distribution, reporting new records of one or more species while providing a complete overview on the known distribution of the treated taxa. -book reviews on books related to biodiversity, biogeography, niche modeling, or any associated field that uses species distribution as its primary data source. -opinions on relevant subjects for the journal’s mission and scope
