在诺福克和豪勋爵群岛，北塔斯曼海，西南太平洋，在86-113米深处收集的7个标本的基础上，描述了一种新的小型蝎子鱼，Scorpaena bulacephala。这种新物种与夏威夷特有物种S. colorata密切相关。这两个物种与其他印度太平洋的Scorpaena物种的区别在于以下特征的组合：暴露的摆线鳞片覆盖身体的前腹面和胸鳍基部，泪腺的侧面没有刺，以及17条胸鳍射线。新种与大黄鱼的不同之处是有39-44排纵鳞，鳍刺和鳍线相对较短，尤其是最长的胸鳍线较短（约为标准长度的31.5-33.5%）。并讨论了新种的生长形态变化和两性二态性。
A new species of small-sized scorpionfish, Scorpaena bulacephala, is described on the basis of seven specimens collected from off Norfolk and Lord Howe Islands, northern Tasman Sea, southwestern Pacific Ocean, at depths of 86–113 m. The new species is closely related to a Hawaiian endemic species, S. colorata. The two species are distinguished from other Indo–Pacific species of Scorpaena by the following combination of characters: exposed cycloid scales covering the anteroventral surface of the body and pectoral-fin base, the lateral surface of the lacrimal without spines, and 17 pectoral-fin rays. The new species differs from S. colorata in having 39–44 longitudinal scales rows and relatively short fin spines and rays, especially short longest pectoral-fin ray (31.5–33.5% of standard length). Morphological changes with growth and sexual dimorphism of the new species are also discussed.
