对短翅亚目的分类学修订导致了三个有效的物种。锯缘短鳍鱼（Brachypterois serrulifer Fowler 1938）是锯缘短鳍鱼（BrachypteroisserrulatusRichardson 1846）的次异名，其胸鳍鳍条通常为16条（与同类15）和0-22棘上颌骨的中侧脊（与几乎总是缺席），除了较长的背鳍和肛鳍软射线，相对较少的大黑点的尾鳍，和后泪刺通常指向腹侧。弯刺短翅虫Brachypterois curvispina sp. nov.，根据32个标本的描述，可以将其与B区分开来。serrulata（Richardson 1846）的纵向系列鳞片行数较少，为41-45（而B为44-51）。serrulata）;相对较长的头部，其长度为41.6-44.5（平均43.1）% SL [vs. 38.3-43.1（平均40.2）% SL];后泪棘通常指向后方，在大型男性中尖端强烈向上弯曲（vs.简单指向腹后）;以及在外角嵴的后角上向后指向的棘（vs.指向腹侧）。锯齿短鳍鱼（Brachypterois serrulifer）在印度-西太平洋分布广泛，而B. curvispina sp. nov.和B. serrulata分别局限于澳大利亚东北部和太平洋西北部。详细描述了种内变异，包括性二型和个体发育的变化。采自台湾南部的一新模式种，命名为S. 1846年。
A taxonomic revision of the scorpaenid genus Brachypterois resulted in three valid species. Brachypterois serrulifer Fowler 1938, previously regarded as ajunior synonym of Sebastes serrulatus Richardson 1846, can be distinguished from its congeners by having usually 16 pectoral-fin rays (vs. 15 in the congeners) and 0-22 spines on the median lateral ridge of the maxilla (vs. almost always absent), in addition to longer dorsal- and anal-fin soft rays, relatively fewer large dark spots on the caudal fin, and the posterior lacrimal spines usually directed ventrally. Brachypterois curvispina sp. nov., described on the basis of 32 specimens, can be distinguished from B. serrulata (Richardson 1846) by having fewer number of scale rows in the longitudinal series 41-45 (vs. 44-51 in B. serrulata); relatively long head, its length 41.6-44.5 (mean 43.1)% SL [vs. 38.3-43.1 (mean 40.2)% SL]; posterior lacrimal spines usually directed posteriorly, with the tip curved strongly upward in large males (vs. simply directed posteroventrally); and posteriorly directed spine(s) on the posterior corner of the outer angular ridge (vs. directed ventrally). Brachypterois serrulifer is distributed widely in the Indo-West Pacific, whereas distributional ranges of B. curvispina sp. nov. and B. serrulata are restricted to northeastern Australia and the northwestern Pacific, respectively. Intraspecific variation, including sexual dimorphism and ontogenetic changes in the three species are described in detail. A neotype, collected from southern Taiwan, is designated for S. serrulatus Richardson 1846.
