| Abstract |
Monophyly of a redefined Grammatidae consisting only of Gramma Poey and Lipogramma Bohlke is supported by synapomorphic modification of the cheek musculature: adductor mandibulae with a separate A portion lying lateral to the levator arcus palatini. The position of the Grammatidae in the Perciformes remains uncertain. Contrary to recent studies, its traditional placement with the percoid "disjunct lateral-line serranoids" (Opistognathidae,Plesiopidae and Pseudochromidae) is not corroborated by present evidence. Monophyly of the Notograptidae, containing only Notograptus Günther, is supported by numerous autapomorphies,including: anterior expansion of the median ethmoid; a large section of the adductor mandibulae that originates broadly on the skull, preopercle, and suspensorium; and a highly reduced gill-arch skeleton. Of several competing hypotheses, current evidence favors a relationshipof notograptids to acanthoclinine plesiopids. |
