- Abstract: The Stevardiinae are a high diverse subfamily of Characidae, the richest family of Neotropical fishes. Many species are inseminating (internal fertilization) and consequently display diverse morphology of reproductive organs and sperm cells. We test the monophyly and internal relationships of the Stevardiinae through a phylogenetic analysis based on a new set of morphological characters, including reproductive traits, combined with publicly available molecular data. We defined 176 characters from general morphology and primary and secondary sexual characters, coded for 54 species. Analyses were made under parsimony using a broad range of extended implied weighting parameters. Given the different morphological characters we use, this analysis provides additional synapomorphies and an independent test for previous hypotheses based on morphological and combined morphological and molecular datasets. Our final hypothesis is a single most parsimonious tree of 6341 steps obtained under three different weighting schemes. This recovers the monophyly of the tribes Creagrutini, Diapomini, Glandulocaudini, Hemibryconini, Landonini (including Eretmobryconini), Stevardiini, and Xenurobryconini. It also supports the recognition of the monotypic tribe Phenacobryconini. Insemination is ambiguously optimized as present in the common ancestor of Stevardiinae and in the common ancestor of all members of the subfamily except for Landonini. That reconstruction constitutes a novelAbstract: The Stevardiinae are a high diverse subfamily of Characidae, the richest family of Neotropical fishes.

Abstract : Many stevardiin tetras are inseminating and display diverse morphology of reproductive organs and sperm cells, which we analyzed through a dataset of available molecular data and 176 morphological characters for 54 species. Parsimony analyses corroborated the monophyly of the tribes of Stevardiinae with Landonini including Eretmobryconini and a valid Phenacobryconini. Insemination was ambiguously optimized as present in the ancestor of Stevardiinae, which is a novel hypothesis on its evolution. Resumen: Los Stevardiinae son una subfamilia altamente diversa de Characidae, la familia más rica de peces neotropicales. Muchas especies son inseminadoras (con fertilización interna) y, en consecuencia, presentan diversas morfologías en los órganos reproductivos y células espermáticas. Testeamos la monofilia y relaciones internas de los Stevardiinae a través de un análisis filogenético basado en un nuevo conjunto de caracteres morfológicos que incluye aspectos reproductivos, combinado con datos moleculares de uso público. Definimos 176 caracteres de morfología general y caracteres sexuales primarios y secundarios, codificados para 54 especies. Los análisis fueron hechos bajo parsimonia en un amplio rango de parámetros de pesos implicados extendidos. Dados los diferentes caracteres morfológicos que usamos, este análisis provee sinapomorfías adicionales y un test independiente para las hipótesis previas basadas en matrices morfológicas y combinadas. Nuestra hipótesis final es un único árbol más parsimonioso de 6341 pasos, obtenido bajo tres diferentes esquemas de pesado. Este árbol recupera la monofilia de las tribus Creagrutini, Diapomini, Glandulocaudini, Hemibryconini, Landonini (incluyendo Eretmobryconini), Stevardiini y Xenurobryconini. También apoya el reconocimiento de la tribu monotípica Phenacobryconini. La presencia de inseminación se optimiza de manera ambigua como presente en el ancestro común de los Stevardiinae y en el ancestro de todos los miembros de la subfamilia excepto los Landonini. Esta reconstrucción constituye una hipótesis novedosa sobre la evolución de la inseminación en Characidae. … (more)
