Symphysanodontidae (Slopefishes)
Etymology: Symphysanodon: Greek, syn, symphysis = grown together + Greek, physis = growth body form + Greek, odous = teeth; related to few teeth which are located over the area where the two jaws meet (Ref. 45335); xanthopterygion: The name xanthopterygion is from the Greek xanthos (yellow), pterygion (fin)—referring to the yellow coloration of the lower caudal-fin lobe. The specific name of the new species is a noun in apposition to the generic name Symphysanodon (Ref. 87359).
