The genusPseudojuloides构成了一系列梭形鱼雷形状的卷曲,带有凿子,就像切入的牙齿一样,经常被发现生活在失去的沙质瓦砾中而不是通常的珊瑚覆盖物中。Pseudojuloideswas last revised in 1981 where five new species were added to the original three. Since then, the genus has been growing steadily with the description ofPseudojuloides kaleidos,P. severnsi和P. edwardi分别在1995年,2000年和2014年。当前日期的该属属于描述成员的十二个成员,还有一些其他未知数等待科学分析和描述。可以肯定地Pseudojuloides像最近一样,将继续扩大规模P. polackorum是该属的第十二任官方成员。
像以前的新物种一样Pseudojuloides edwardi,P. polackorumis native to Africa, more specifically near the southern coast. It ranges to Kenya as well as Madagascar, but is replaced by伪juloides xanthomosin Mauritius.P. polackorum与官方科学描述之前相比,在贸易中比在野外更为知名的物种是独一无二的。尽管非常罕见,但它确实通过非洲进口物(例如日本上面的进口)零星出现。格林威治水族馆的杰森·爱德华(Jason Edward)在通过水族馆进口的官方描述中采购标本方面也非常重要。
The males of this species resembleP. cerasinus, but differ in having a wide lateral orange midline that extends horizontally starting past the pectoral fins. The stripe is bounded by blue which on the upper portion, often extends linearly into the orange forming a zipper pattern. The body is emerald fading to a lighter shade ventrally, and the lower portion of the face is salmon washed. The tail bears a black margin edged in blue. Females like many others in the genus, are uniformly salmon pink with yellow washing on the head and the median fins.
This species is another member of thecerasinuscomplex, but differs greatly in coloration as well as mitochondrial DNA barcode sequences. As mentioned above, this species ranges in the South Western Indian Ocean along the Southern African coast to Kenya and north to Madagascar. In the oceanic islands such as Mauritius, it is replaced byP. xanthomos, which bears a superficial resemblance except that the orange lateral band is reduced to a yellow epaulette behind the pectoral fin.
伪juloides polackorumwas named in honour of Dennis and Sally Polack, whose underwater photos first brought this species to attention. The specific epithet “polackorum” in this case is used as a noun in the genitive case. For more information and the full paper, this species description is published in the Journal of the Ocean Science Foundation, volume 14.
