The River goby genus Awaous are prominent members of riverine ichthyofaunas and occur throughout Atlantic and Pacific slopes of the Americas from the southern United States to Ecuador and Brazil. Here we study the widespread and polymorphic Awaous banana complex to assess phylogeographic patterns and test previous hypotheses that all populations of this species in the Americas belong to the same species. Analysis of sequence data based on the mitochondrial cytochrome oxidase I gene shows multiple clades within the Atlantic and Pacific basins, which correspond to previously described species. Additionally, haplotype analysis demonstrates unique and unconnected networks between these species. Within these clades we document biogeographic patterns that are congruent with results of other co-occurring diadromous species, as well as a novel biogeographic pattern for the region. Our results support the recognition of distinct species of Awaous in the Atlantic (A. banana and A. tajasica) and Pacific (A. transandeanus) basins. These results are concordant with previously established morphological characters permitting the separation of these species.© 2021 Fisheries Society of the British Isles.McMahanCaleb DCDhttps://orcid.org/0000-0003-2113-8554Field Museum of Natural History, Chicago, Illinois, USA.ElíasDiego JDJhttps://orcid.org/0000-0003-4215-0384LSU Museum of Natural Science, Department of Biological Sciences, Louisiana State University, Baton Rouge, Louisiana, USA.LiYueYLSU Museum of Natural Science, Department of Biological Sciences, Louisiana State University, Baton Rouge, Louisiana, USA.Domínguez-DomínguezOmárOLaboratorio de Biología Acuática, Facultad de Biología, Universidad Michoacana de San Nicolás de Hidalgo, Morelia, Mexico.Rodriguez-MachadoSheilaSLSU Museum of Natural Science, Department of Biological Sciences, Louisiana State University, Baton Rouge, Louisiana, USA.Morales-CabreraAlejandraAEscuela de Biología, Facultad de Ciencias Químicas y Farmacia, Universidad de San Carlos de Guatemala, Guatemala City, Guatemala.Velásquez-RamírezDianaDEscuela de Biología, Facultad de Ciencias Químicas y Farmacia, Universidad de San Carlos de Guatemala, Guatemala City, Guatemala.PillerKyle RKRhttps://orcid.org/0000-0003-1289-9351Department of Biological Sciences, Southeastern Louisiana University, Hammond, Louisiana, USA.ChakrabartyProsantaPhttps://orcid.org/0000-0003-0565-0312LSU Museum of Natural Science, Department of Biological Sciences, Louisiana State University, Baton Rouge, Louisiana, USA.MatamorosWilfredo AWAhttps://orcid.org/0000-0002-6241-5354Colección de Ictiología, Instituto de Ciencias Biológicas, Universidad de Ciencias y Artes de Chiapas, Tuxtla Gutiérrez, Mexico.engJournal Article20210607EnglandJ Fish Biol02140550022-11120DNA, MitochondrialIMAnimalsDNA, MitochondrialgeneticsFishesgeneticsGenetic VariationPhylogenyPhylogeographyRiversMiddle AmericaNeotropicsbiogeographygobyphylogeographyrivers2021050720210323202105102021516602021923602021515835ppublish3399111110.1111/jfb.14783Microsc Res TechMorphological and microstructural characteristics of scales in longnose goby Awaous jayakari (Teleostei: Gobiidae): Light and scanning electron microscopy approaches.10.1002/jemt.23871The scale morphology of a native goby, Awaous jayakari (Gobiidae) was studied using scanning electron microscopy and light microscopy. The morphological descriptions were based on the scale's type, shape, and features of the anterior, posterior, and lateral fields. Further characteristics of the focus, circuli, radii, lepidonts, and cteni, were investigated. Morphometric indices were calculated for some scales. Shape variability of scales was high in different regions. However, the majority of scales displayed a polygonal shape (hexagonal and pentagonal). Both ctenoid and cycloid scales were observed in the studied fishes. The ctenoid scale of A. jayakari was peripheral and characterized by the presence of one row of marginally located spines in two completed and uncompleted subtypes. The focus was positioned posteriorly or postero-centrally. The microscopic examinations revealed the presence of lepidonts of different sizes being very tiny, small, or prominent performing flat, blunt, pointed, short, or truncated shapes. The rostral margin of the scales was convex to moderately flattened and represented striate, scalloped, or waved types. Lateral fields were often flattened in all regions, while convex in the lateral fields of the scales of some individuals. The posterior field showed variations in different regions, for example, tapered and flattened ends. The anterior-posterior axis presented a laterally expanded or an elongated extension. The considerable morphological variation in the scales of various body regions makes it difficult to nominate a typical scale to be used in taxonomic studies. However, the key scales can be used for the comparison of different Awaous species.© 2021 Wiley Periodicals LLC.Al JufailiSaud MSMhttps://orcid.org/0000-0002-0930-5754Department of Marine Science and Fisheries, Sultan Qaboos University, Muscat, Oman.Natural and Medical Sciences Research Center, University of Nizwa, Nizwa, Oman.MasoumiAmir HassanAHIchthyology and Molecular Systematics Research Laboratory, Zoology Section, Department of Biology, School of Science, Shiraz University, Shiraz, Iran.EsmaeiliHamid RezaHRhttps://orcid.org/0000-0002-9736-397XIchthyology and Molecular Systematics Research Laboratory, Zoology Section, Department of Biology, School of Science, Shiraz University, Shiraz, Iran.Center for Hydrobiology and Aquatic Biotechnology, Shiraz University, Shiraz, Iran.JawadLaithLhttps://orcid.org/0000-0002-8294-2944School of Environmental and Animal Sciences, Unitec Institute of Technology, Auckland, New Zealand.TeimoriAzadAhttps://orcid.org/0000-0001-5537-725XDepartment of Biology, Faculty of Sciences, Shahid Bahonar University of Kerman, Kerman, Iran.engSU-9233856Shiraz UniversityCR/AGR/FISH/20/03Sultan Qaboos UniversityGeo-Resources Environmental and Earth Science ConsultantsJournal Article20210722United StatesMicrosc Res Tech92030121059-910XIMGobiiformesscale morphologystructural designsurface ornamentationsystematics20210620202105222021070220217221240202172360202172360aheadofprint3429265310.1002/jemt.23871
