Prolific Ph.D. candidateLemon Tyk,布莱恩·格林(Brian D.Pseudojuloides crux和P.paradiseusare now being joined byP.冥王星和P. proserpina, bringing the total number of铅笔炒种到18。
后两个物种的描述是在报道的波利尼西亚人,Pseudojuloides atavai,being seen outside of its usual region in French Polynesia and the surrounding islands. Co-author Brian D. Green told Reefbuilders the work actually goes back 17 years with most of the types collected by 2005, but they were not able to collect tissue samples ofP.冥王星直到去年,直到现在才能确定是否要完成全面的系统工作P. atavaiwas a single widespread species or if those with male color differences from northwest Micronesia were actually new.
Morphological and molecular studies on the different populations ofP. atavaiwere carried out, and the two new species are the result of that study.

The Narcissus Pencil Wrasse,伪juloides冥王星
伪juloides冥王星comes from patch reefs over a sand/rubble bottom in Wake Island, and the Northern Mariana Islands, Northwest Micronesia. It differs from its congeners in having a deeper body in relation to its length, with males olive green dorsally, fading to whitish green ventrally, although this is usually obscured by black in terminal males.
Females look very similar toPseudojuloides atavai(因此,混乱),用粉红色的红色条纹从嘴巴到尾巴的顶部。标本也小于P. atavaiwith the maleP.冥王星holotype being 78mm in length, versus 121mm for the maleP. atavai研究中的标本。
It’s named after Pluto, god, and king of the underworld in Roman mythology, in reference to the nefarious and sinister appearance of the males. The contrasting beauty of the females is reminiscent of Narcissus flowers according to the authors, a sacred symbol of Pluto that grew along the River Styx at the boundary of the underworld.
石榴铅笔炒,伪juloides proserpina
The Pomegranate pencil wrasse was found over a rubble terrace adjacent to a drop-off on the northwest face of Fatu Hiva, Marquesas, French Polynesia. It’s been described only from the 91mm long male holotype, with female coloration in life unknown, according to the paper. But withP.atavainow thought to be a species complex, female coloration may well be similar to that ofP.atavai和Pluto。雄性具有网状头图,乳房上有宽阔的粉红色带子,胸部宽阔的粉红色带和明亮的黄色背鳍。
它以罗马神话中黑社会女神Proserpina的名字命名P.冥王星。胸鳍背后的蜂窝状图与石榴果的种子内部相似,这是一个神圣的符号,在Proserpina的神话中显着,并被冥王星绑架到黑社会中。拟合功能,以及两个新物种的巧妙命名搭配。
它与特有的分布P. Pyrius和given the high levels of endemism in the Marquesas, it is likely thatP. proserpina该地区也是地方性的。仅在25米的深度上观察到它一次,并被认为居住在30m以上,比两者都深P.atavai和Pluto在。对中虫的珊瑚礁的深度和缺乏探索也可以解释其稀有性。
The Polynesian Wrasse, Narcissus Wrasse, and Pomegranate Wrasse are three stunning species of Pencil Wrasse that will no doubt send wrasse-collecting reefer’s pulses racing, especially the coloration and pattern of the three-terminal males.
We were lucky to see a trio of Polynesian wrasses at Atlantis Aquarium in Germany in 2014, with the original write-up done by none other than the co-author of the paper on the two new species, Lemon Tyk. It’s safe to say thatvideo footage留下持久的印象。
