Abstract
A new species of the scaleless black dragonfish genus Melanostomias is described based on a single specimen (180 mm SL) collected off the northern Fernando de Noronha Archipelago (Brazil), western Tropical Atlantic. It differs from its congeners in having a unique barbel morphology, which ends in a bulb with two opposite slender terminal appendages. In addition, the occurrences of Melanostomias melanops and M. valdiviae are confirmed in Brazilian waters based on examination of new material. An overview analysis of the distribution and meristic variation of the species within the genus is also provided.
根据在热带大西洋西部费尔南多-迪诺罗尼亚群岛(巴西)北部采集的单个标本(180 mm SL),描述了无鳞黑龙鱼属Melanostomias的一个新种。它不同于它的同系物具有独特的倒钩形态,它的末端是一个球茎,有两个相对的细长的末端附属物。此外,根据对新材料的检查,确认在巴西水域中出现了黑色黑口虫和瓦尔迪维亚黑口虫。对属内的分布和分生变异进行了综述分析。
