Terelabrus目前是1998年首次建立的单型属,该属是基于新喀里多尼亚Bulari Pass的100m捕获的一个未知的Labrid。从那时起,尽管出现了两个潜在的新物种,但该属并未扩展,其中一种是来自印度洋。在水族馆贸易中,这三个不同的外观Terelabrusspecies have surfaced, of which two are ratheruncommonwhile one is exceedingly rare. It is worthy of mention that there could be a mix up in identity here, andTerelabrus rubrovittatus可能会错误地给予爱好阵线中错误的物种。
The picture above are of the original holotype and paratype ofT. Rubrovittatus。The larger male of 87mm was caught in a trap at 100m in New Caledonia in 1979. It was only 16 years later in 1995 where another specimen was caught, a 32mm juvenile at 92m in Milne Bay. The distinctively different body profile and meristics warranted an erection of a new genusand a new species,Terelabrus rubrovittatus。The generic epithetTerelabrus是拉丁单词的融合teres,意为terete和拉布鲁斯由于鱼的狭窄圆柱形或tere骨形状,因此扭动。特定的词rubrovittatusmeans red stripe.
Taking a closer look atTerelabrus rubrovittatus在整型照片和描述论文中,您会注意到,在成人阶段,鱼具有黄色的背鳍。身体是白色的,有两个水平的红色条纹。一个狭窄的狭窄的横穿背侧,一个大致分割的条纹横向横向延伸。最初的类型和副型标本是在新喀里多尼亚和米尔恩湾PNG中收集的,但在日本的Deepwater Japan也发现了这些样本,在那里收集了上面的个人。
在深海挑战者上方的标本中,鱼从头到尾的尺寸为5英寸,并用大型鱼类保存Odontanthias katayamaiandBodianus Masudai。This size factor is important when we’re comparing it again later to another similar and wrongly labelledTerelabrus。
A smaller, more common species ofTerelabrus已经从印度尼西亚出现了几年。该物种较小,外观更苗条,颜色不同。但是,它被错误地给出了与前面物种相同的名称,T. Rubrovittatus, and is listed as such in many websites as well as literature. Comparing this to the holotype ofT. Rubrovittatus, the difference is quite clear. In none of these Indonesian specimens are the unpaired fins yellow. The middle stripe is narrow and even, and the zone between the two red stripes is yellow, a trait unseen in the trueT. Rubrovittatus。The face also possess blue and yellow squiggles just below the eye in certain usually larger specimens.
Not only is this unknownTerelabrussmaller, more slender and coloured differently, they are also found in generally much shallower waters. In the originalT. Rubrovittatus, specimens were only seen and collected near 100m depth. The unknownTerelabrus但是,在这里可以找到黄色条纹,深度高达20m。虽然他们可以住在很多深度更大,它们最常在不正确的地方看到和拍照T. Rubrovittatus到目前为止已找到。
LikeT. Rubrovittatus但是,该物种范围为日本以及中太平洋地区的许多地区,经常被日本潜水员和摄影师拍摄。在许多潜水博客(例如Kazkian)中,它们被标记为Terelabrus sp。Elsewhere however, they have been erroneously identified asT. Rubrovittatus多年来,尤其是在水族馆贸易中。与导致混乱的这种未知物种的相对丰度相比,这可能是由于真实物种的稀缺性。但是,如果您比较这两个物种,您会发现颜色,形态和对深度的一般偏好的差异很容易使这两个物种分开。
还定期向贸易提供了尚待描述和确定的第二种物种,该物种来自印度洋的马尔代夫。像Terelabrus spfrom the pacific, this species is smaller, more slender and coloured differently fromT. Rubrovittatus。鱼具有相同的一般图案,具有两个水平红色条纹的白色身体。但是,在该物种中,两条带之间没有其他黄色条纹,并且鱼通常看起来更白。
In large specimens the tail may be slightly lanceolated along the central rays. The main distinguishing characteristic for this species with the previous is the lack of yellow and the difference in range. Assuming we are correct, there should now be potentially two additional species ofTerelabrus.However the name “Terelabrus rubrovittatus“已经被给予并用于错误的物种,现在很难改变。然而,我们希望将来这两个未描述的物种有机会得到适当的研究,并希望这将使事情变得正确。
上面是真实的视频Terelabrus rubrovittatus, just as a final look for comparison. Notice how large it is, the coloration as well as the physical form compared to the two other smaller members.
