Abstract—

The second specimen of the rare species Photonectes uncinatus, previously known only by the holotype from the Rio Grande Rise (Southwest Atlantic), was discovered in the samples of Melanostomiidae from the Walvis Ridge made by I.A. Trunov in 1976. The redescription of the species taking into account new data is provided, and the individual variability of a number of diagnostically significant morphological characters is clarified. It has been established that the features of the arrangement of teeth on the palatinum are of diagnostic value for definition of the groups of species within the genus Photonectes. Based on published data, P. uncinatus is also indicated for waters of New Zealand (Bounty Plateau). The type of range of this species is discussed.

在沃尔维斯山脊（东南大西洋）上发现光子菌，物种重新命名（黑毛纲科）

摘要—

1976年IA Trunov在Walvis Ridge的Melanostomiidae样本中发现了稀有物种Photonectes uncinatus的第二个标本，以前仅通过Rio Grande Rise（西南大西洋）的整型才知道。考虑到提供了新数据，并阐明了许多具有诊断意义的形态特征的个体差异。已经确定的是对牙齿palatinum的排列的特征是对属内的品种组的定义的诊断价值Photonectes。根据已发布的数据，P。uncinatus也适用于新西兰（赏金高原）的水域。讨论了该物种的范围类型。
