【生物资讯】铅笔鱼新物种Pseudojuloides polynesica & P. splendens

铅笔鱼属Pseudojuloides新增了两个新物种：色彩斑斓的铅笔鱼Pseudojuloides splendens和波利尼西亚铅笔鱼Pseudojuloides polynesica。这两种新隆头鱼物种的外貌与彩色小尾铅笔鱼P. cerasinus相似，但它们的外观和分布区域不同。

色彩斑斓的Pseudojuloides splendens

这条铅笔鱼是在日本到澳大利亚一带的西太平洋海域发现的，与夏威夷的铅笔鱼相似。P. splendens与P. cerasinus雄性的身体整体为绿色，尾巴边缘为黑色。普通雄性绿色铅笔鱼的面部只有一条蓝色条纹，而P. splendens有两条。此外，P. splendens这种铅笔鱼的背部有一条明显的橙色条纹，从鼻子一直延伸至背鳍和尾巴末端。

波利尼西亚铅笔鱼Pseudojuloides polynesica

这条鱼是在法属波利尼西亚至塔希提岛一带的南太平洋中发现的。该物种的雄性外观呈明显的黄色，和P. cerasinus一样，面部有一条蓝色条纹，但它的尾部没有黑色着色。

Pseudojuloides polynesica和P. splendens已成为新的隆头鱼种类。班杰明·维克托（Benjamin Victor）在Ocean Science Foundation杂志上描述了这两种鱼。

The pencil wrasse genus Pseudojuloides just increased by two more new species, the splendid pencil wrasse, Pseudojuloides splendens and the Polynesian Pencil Wrasse, Pseudojuloides polynesica. Both of these two new pencil wrasses are similar in appearance to the colorful s m a lltail pencil wrasse P. cerasinus but differ both in appearance and in their distribution.

Pseudojuloides splendens, the splendid pencil wrasse

The splendid pencil wrasse is found in the western pacific ocean from Japan to Australia and is the most similar to its Hawaiian counterpart. The body of males is an overall green color with a black edged tail in both P. splendens and P. cerasinus but the males of the common green pencil wrasse have just one blue facial stripe while P. splendens has two. Furthermore the splendid pencil wrasse has a pronounced orange dorsal stripe running from the snout all the way across the dorsal fin to the base of the tail.

Pseudojuloides polynesica, the polynesian pencil wrasse

Meanwhile the polynesian pencil wrasse, Pseudojuloides polynesica is found in the South Pacific Ocean from Rangiroa and Tahiti in French Polynesia. This species has a distinctly yellow appearance in males, with a single blue facial stripe like P. cerasinus but no black in the tail.

Pseudojuloides polynesica and P. splendens join a growing list of new species of beautiful pencil wrasses that have been described in recent years including P. zeus & P labyrinthus. The polynesian pencil wrasse and splendid pencil wrasse were described by Benjamin Victor in the Journal of the Ocean Science Foundation.
