摘要

目前學者大多將一種廣泛分布於印度太平洋海域的羊魚（鬚鯛）稱作雙帶海鯡鯉Parupeneus bifasciatus （Lacepède），但第一位整理此科魚類的分類學者Günther（1859）在同頁的報告中正確地將該種歸於三帶海鯡鯉P. trifasciatus （Lacepède）中的同種異名。本文則將三帶海鯡鯉種群P. trifasciatus complex再分成為三種。其中真正的三帶海鯡鯉P. trifasciatus侷限在印度洋，厚唇海鯡鯉P. crassilabris （Curvier）分布於東印度洋及西太平洋至斐濟、東加、卡羅林島。牠與三帶海鯡鯉之差別在顏色及頦鬚較短。紅眼海鯡鯉Parupeneus insularis則分布於夏威夷、法屬波里尼西亞、Pitcairn島到馬紹爾、馬里安那、鳳凰及薩摩亞群島。其特徵為體色不同，鯉耙數37-42（大多為39），較其它兩種魚鰓耙之35-38為多，此外其頦鬚也較厚唇海鯡鯉更短。

Most recent authors have used the name Parupeneus bifasciatus (Lacepède) for a wide-ranging Indo-Pacific goatfish; however, Günther (1859), as 1st revisor, correctly placed bifasciatus in the synonymy of trifasciatus described by Lacepède on the same page. We herein divide P. trifasciatus into 3 species and restrict P. trifasciatus to the Indian Ocean. Parupeneus crassilabris (Cuvier) is recognized as valid for the eastern Indian Ocean and the western Pacific east to Fiji, Tonga, and the Caroline Islands; it differs from trifasciatus in color and in having shorter barbels. Parupeneus insularis is described as a new species from the Hawaiian Islands, French Polynesia, and Pitcairn Islands to the Marshall, Mariana, Phoenix, and Samoa Islands; it differs in color and in having a higher gill-raker count, 37-42 (modally 39), compared to 35-38 for the other 2 species, and it has shorter barbels than P. crassilabris.
