Terelabrusis at the moment a monotypic genus first erected in 1998 based on an unknown labrid caught at 100m in Bulari Pass, New Caledonia. Since then, the genus has not expanded despite the appearance of two potentially new species, one of which from the Indian Ocean. In the aquarium trade, these three different lookingTerelabrus物种浮出水面,其中两个是罕见虽然非常罕见。值得一提的是,这里的身份可能会混在一起,TerelabrusRubrovittatusmay be erroneously given to the wrong species in the hobby front.
上面的图是原型的原型和副类型T. rubrovittatus。1979年,在新喀里多尼亚的100m处被捕获的87毫米较大的雄性在100m的陷阱中被捕。1995年后,仅16年后,另一个标本被捕获,在米尔恩湾(Milne Bay)捕获了32毫米少年。明显不同的身体概况和富版本必须竖立新属还有一个新物种TerelabrusRubrovittatus。通用词Terelabrusis an amalgamation of the latin wordsteres, meaning terete andlabrusfor wrasse owing to the narrow cylindrical or terete shape of the fish. The specific epithetRubrovittatus意味着红色条纹。
仔细研究TerelabrusRubrovittatusin the holotype photos and in the description papers, you’ll notice the fish, in the adult stage, has a yellow dorsal and anal fin. The body is white with two horizontal red stripes; a narrow one running across the dorsum and one roughly segmented and thicker stripe running laterally just below. The original type and paratype specimens were collected in New Caledonia and Milne Bay PNG, but they have also been found in deepwater Japan, where this individual above was collected.
In this specimen above from Deep Sea Challengers, the fish measured 5 inches from head to tail, and is kept with big boisterous fish likeOdontanthias katayamai和Bodianus masudai。当我们稍后再将其与另一个类似且错误的标签进行比较时,这种尺寸因素很重要Terelabrus。
一个较小,更常见的物种Terelabrushas been showing up for a couple of years now from Indonesia. This species is smaller, more slender in appearance and coloured differently. However it has been erroneously given the same name as the preceding species,T. rubrovittatus,并且在许多网站和文献中都被列出。将其与原型进行比较T. rubrovittatus,差异很明显。这些印尼标本中没有一个是未配对的鳍黄色。中间条纹狭窄,甚至均匀,两条红色条纹之间的区域是黄色的,在真实的特征中T. rubrovittatus。在某些通常较大的标本中,脸部还在眼睛下方的蓝色和黄色弯曲。
不仅这是未知的Terelabrus较小,更苗条和颜色不同,它们在通常较浅的水中也发现了它们。在原来的T. rubrovittatus,仅看到标本并收集在100m的深度附近。未知Terelabrushere with the yellow stripe can be found however, at depths as shallow as 20m. Although they can live inmuchgreater depths, they are most often seen and photographed at shallower depths where no trueT. rubrovittatushas so far been found.
喜欢T. rubrovittatus然而,这个物种范围Japan as well as many parts of the central pacific where they are often photographed by Japanese divers and photographers. In many of these diving blogs such as Kazkian, they are labelled asTerelabrussp。然而,在其他地方,它们被错误地确定为T. rubrovittatusfor years, especially in the aquarium trade. It is probably due to the scarcity of the real species compared to the relative abundance of this unknown species that led to the confusion. However if you compare the two species you’ll see that the difference in colour, morphology and general preference for depth sets the two species apart easily.
A second species yet to be described and identified has also been offered to the trade regularly, and this species comes out of the Maldives in the Indian Ocean. Like theTerelabrussp来自太平洋,该物种较小,苗条,颜色较小T. rubrovittatus。The fish bears the same general pattern, of having a white body with two horizontal red stripes. However in this species, there is no additional yellow stripe in-between the two bands, and the fish is generally much whiter in appearance.
在大型标本中,尾巴可能沿着中央射线略微弹灯。该物种的主要区别特征是缺乏黄色和范围差异。假设我们是正确的,现在应该有两种额外的物种Terelabrus。但是这个名字“TerelabrusRubrovittatus” has been given and used for the wrong species so long now that it might be hard to change. Nevertheless, we hope that in future these two undescribed species get a chance to be properly studied and hopefully that will set things right.
