Phylogenetic relationships among families of the suborder Notothenioidei (Perciformes) based on morphological features of the cranial musculature.

描述并比较了诺氏鱼类的颌部肌肉结构，共56种，隶属于诺氏鱼类亚目8科。对三叉神经下颌支的位置也作了详细描述。在Notothenioidei中，下颌内收肌是颅肌中最大和最显眼的部分，通常由A1、A2、A3和Aw段组成，在广义的Percoid中也是如此。下颌内收肌的形态在大多数诺氏科中都是相似的，但诺氏科和弓龙科除外。Notothenia，Paranotothenia和Dissostichus与其他Notothenia属的A3有明显的区别。Bathydraconidae的Gymnodraco有一个融合的A1-A2复合体，前面的元件由A1-A2复合体的腱交叉分割。这些情况是Gymnodraco所特有的，在其他深海龙类中没有见过。哈帕吉克科和节虫科的表型相同，都有A1β，与节节科没有同源同型。然而，字符分布与以前的分类显示出一些不一致。有些性状似乎是异时性的结果。根据本研究中获得的有限证据，Notothenioidae可分为六个组，建议对Nototheniidae的现有分类进行审查似乎是合理的。

The jaw musculature of notothenioid fishes is described and compared based on a total of 56 species referred to eight families of the suborder Notothenioidei. The position of ramus mandibularis trigeminus was also described in detail. In the Notothenioidei, the adductor mandibulae, the largest and most conspicuous of the cranial muscles, is generally composed of sections A1,A2,A3 and Aw as in the generalized percoids. The morphology of the adductor mandibulae is similar in most notothenioid families except the Nototheniidae and Bathydraconidae. Notothenia, Paranotothenia and Dissostichus are clearly distinguished from the other nototheniid genera in having A3. Gymnodraco of the Bathydraconidae has a fused A1-A2 complex and the anterior element is segmented by a tendinous intersection from the A1-A2 complex. These conditions are unique to Gymnodraco and not seen in other bathydraconids. The Harpagiferidae and Artedidraconidae share the same apomorphy, the presence of A1β, with the Nototheniidae and have no synapomorphies with the Bathydraconidae and Channichthyidae. The character distribution, however, shows some inconsistencies with the previous classifications. Some characters were appeared to be resulted from heterochrony. Based on the limited evidence obtained in this study, the Notothenioidei can be divided into six groups and it seems reasonable to suggest a review of the current classification of the Nototheniidae.
