摘要

Bleeker氏於1859年依據二尾採自印尼爪哇的標本，描述了一種美麗的鯙類─黃斑蝮鯙Muraena xanthospilos。這種鯙類隨後僅僅被記錄過三次（其中一次是以Poecilophis ornata, Kaup這個無效的次異名被記載），直到現在。本研究依據Bleeker氏的二尾綜模，一尾先前另外記錄過的標本，及三尾最近採集並新增記錄到的較大型標本，重新描述了本種鯙類；設定其新的選模；描述其不同成長階段的斑點、齒式和體型變異；且在此首度提供其新鮮標本的照片記錄。黃斑蝮鯙和其他鯙屬鯙類主要的區別在於：其尾部較短，脊椎骨數較少，及體色斑紋形式明顯不同。

Bleeker described 2 specimens of a beautiful moray eel, Muraena xanthospilos, in 1859. The species has subsequently been reported only 3 times (once as Poecilophis ornata Kaup, a junior synonym) until now. In this study, we redescribe the species based on Bleeker's syntypes, one of the previously recorded specimens, and 3 additional recently collected specimens. A lectotype is designated; the variations of spots, the dentition and the body length formulas of different growing stages are described; and photographs of a fresh specimen are provided for the first time. Echidna xanthospilos differs from other species of Echidna in its shorter tail, smaller number of vertebrae, and distinctive coloration.
