Redescription of the Texas Shiner Notropis amabilis from the southwestern United States and northern Mexico with the reinstatement of N-megalops (Teleostei: Cyprinidae)

2016 by Vcrlag Dr. Friedrich Pfeil, Mnchen, Germany. Notropis amabilis is redescribed based on type and non-type material from the United States (Texas and New Mexico) and Mexico. Notropis megalops is removed from the synonymy of N. amabilis, based on morphological and genetic evidence that the two represent distinct species, and redescribed based on type and non-type material from the United States (Texas) and Mexico. Notropis amabilis is distinguished from N. megalops based on differences in head and body pigmentation, body shape, and the shape of the metapterygoid in the hyopalatine arch. Molecular phylogenetic analyses of one mitochondrial gene (cyt b) and two nuclear genes (RAG1 and S7) and a concatenated data set consisting of all three genes for a small number of North American leuciscine cyprinids, including multiple members of the subgenus Notropis, places N. amabilis and N. megalops in different clades and never within a sister group relationship. The synonymy of N. amabilis and N. megalops is revised and lectotype designations are provided for Alburmis amabilis, A. megalops and Cyprineila macrostoma. A neotype is designated for Cyprineila luxiliodes, which is considered a junior synonym of Cyprineila lutrensis.
