The second and third synapomorphies listed above (130: 0 [right arrow] 1, levator arcus palatini markedly lateral to all bundles of adductor mandibulae; 140: 0 [right arrow] 1, insertion of a significant part of adductor arcus palatini on lateral surface of suspensorium) concern muscular features that were not proposed as potential gymnotiform synapomorphies in previous works.
However, in the Galaxias specimens examined by us some fibers of the A2 lie mesial to the levator arcus palatini but ventrally these fibers meet, and deeply blend with, the remaining fibers of the A2.
Adductor arcus palatini and autopalatine and/or dermopalatine.
0] Part of adductor arcus palatini and/or of muscle differentiated from it not deeply blended with ligaments connecting the anterior region of the suspensorium and the ethmoid region.
0] Whiting those fishes in which there an insertion of the adductor arcus palatini or of a part differentiated from it on the autopalatine and/or dermopalatine (see above), the plesiomorphic condition is to lack an extensor tentaculi.
Adductor arcus palatini and lateral surface of suspensorium.
Anterior and posterior sections of levator arcus palatini.
Dorsolateral and ventromesial sections of levator arcus palatini.
