根据8属24种多线虫的骨学和肌学特征，与文献报道的棘形鱼类和63科86种棘形鱼进行了比较，评价了多线虫科的单系性，并讨论了其与珊瑚科的姊妹关系。多线虫科是一个单系类群，有19个突触构型支持，包括4个独特的特征(头感觉管上存在未命名的骨，第三放射线不支持胸鳍射线，A1切面包含外侧和内侧成分，下斜肌在下锁骨与喙上的杆状突起之间分裂)。此外，还识别了7个胸带特征，其中带具有丝状感官射线，适应泥水中的底栖生物生活。多翅虫科和珊瑚科的姐妹关系由6种突触形态支持，其中包括2种相当罕见的突触(两侧骨盆骨的骨膜和骨盆后部有一条单一的叉骨)和2种独特的特征(后翼突和方形突触的鼻管内侧和前伸)。
The monophyly of Polynemidae was evaluated and its sister relationship with Sciaenidae discussed, based on osteological and myological characters from 24 polynemid species in eight genera, with comparisons with acanthomorph fishes from literature and 86 species in 8 orders and 63 families examined. Polynemidae was inferred as a monophyletic group, strongly supported by 19 synapomorphies, including four unique characters (unnamed bone present on cephalic sensory canal extending from supratemporal, third actinost not supporting pectoral-fin rays, section A1 comprising lateral and medial elements, and division of obliquus inferioris present between lower postcleithrum and rod-like process on coracoid) in percoids. In addition, seven pectoral girdle characters were recognized, with the girdle possessing filament-like sensory rays, an adaptation to benthic life in muddy water. The sister relationship of Polynemidae and Sciaenidae was supported by six synapomorphies, including two rather rare (a single branchiostegal ray suspended by epihyal and posterior portions of pelvic bones on both sides interdigitated) and two unique characters (metapterygoid and quadrate interdigitated medially and anterior extension of the nasal canal).
