dc.description.abstract "The discovery of an undescribed species of synbranchiform eel, with populations in the Atlantic slope of Mexico, Guatemala, Honduras, Cuba, and northeastern South America, presented problems in its taxonomic assignment that required a review of the genera and higher groups within the order. Analyses of superficial anatomy, skull, and vertebral column, but particularly of the detailed structure of the hyoid, gill arch, and branchial vascular systems indicated that some of the groups of synbranchiform species are paraphyletic and others polyphyletic, and that the Alabetidae, long associated with the swamp eels, should be excluded from the assemblage. A phylogenetic hypothesis is put forward that divides all synbranchiforms (treated here as the single family Synbranchidae) into two lineages: the Macrotreminae (containing only Macrotrema caligans) and the Synbranchinae (including three genera: Ophisternon (containing the species bengalense, gutturale, candidum, afrum, infernale, and the new neotropical form aenigmaticum), Synbranchus (containing marmoratus and madeirae), Monopterus (containing albus, boueti, cuchia, fossorius, and two forms originally described under the name indicus)). The generic names Furmastix and Anomatophasma are placed in the synonymy of Ophisternon, and Typhlosynbranchus and Amphipnous are placed in the synonymy of Monopterus. The nomenclatural histories of the genera and some species are discussed and an analytical key to the subfamilies, genera, and species is provided"--P. 5. en_US

Files in this item

This item appears in the following Collection(s)

  • Bulletin of the American Museum of Natural History
    The Bulletin, published continuously since 1881, consists of longer monographic volumes in the field of natural sciences relating to zoology, paleontology, and geology. Current numbers are published at irregular intervals. The Bulletin was originally a place to publish short papers, while longer works appeared in the Memoirs. However, in the 1920s, the Memoirs ceased and the Bulletin series began publishing longer papers. A new series, the Novitates , published short papers describing new forms.
