A new species of chimaeroid, Chimaera opalescens n. sp., was described from 31 type specimens caught in the north-eastern Atlantic Ocean at 950-1400 m depth. This species differed from all its congeners by the combination of the following characters: body uniformly pale brown to bronze, iridescent on fresh specimens; unpaired fins brown to purple, uniformly coloured or with pale or whitish edges; iris black; claspers tripartite and divided for a third of their length, not extending beyond the pelvic fins in adults; dorsal spine equal to or shorter than first dorsal fin; ventral caudal lobe equal to or deeper than dorsal caudal lobe. Comparison of DNA sequences of the CO1 gene with those of related species supported C. opalescens n. sp. as a distinct species. Specimens of C. opalescens n. sp. were previously misidentified as Chimaera monstrosa, a species sharing a similar geographical distribution. Chimaera opalescens n. sp. lives in deeper water and is a larger-bodied species than C. monstrosa. The two species were newly exploited by deep-sea fisheries and confused under a single landing name.
一种新的拟鲨类物种，波纹拟鲨（Chimaera opalescens n. sp.），根据在东北大西洋 950-1400 米深处捕获的 31 个模式标本进行了描述。该物种与所有近缘种的区别在于以下特征的组合：身体均匀呈浅棕色至青铜色，新鲜标本具有虹彩；无偶鳍呈棕色至紫色，颜色均匀或具有浅色或白色边缘；虹膜黑色；鳍脚三部分分开，长度为三分之一，在成鱼中不超过臀鳍；背刺等于或短于第一背鳍；腹尾叶等于或深于背尾叶。CO1 基因的 DNA 序列比较支持波纹拟鲨（Chimaera opalescens n. sp.）作为一个独特的物种。波纹拟鲨（Chimaera opalescens n. sp.）的标本以前被错误地鉴定为波纹拟鲨（Chimaera monstrosa），这是一种分布相似的物种。波纹拟鲨（Chimaera opalescens n. sp.）生活在更深的水域，是一种比波纹拟鲨（Chimaera monstrosa）体型更大的物种。这两个物种最近被深海渔业开发利用，并在一个单一的登陆名称下混淆。
