In the present study, we used integrative taxonomy to describe a population of Diploechiniscus oihonnae (Richters, 1903) from the neotype locality in Merok (Norway). We found no differences in the chaetotaxy formula between the life stages and sex of Dpl. oihonnae. The presence of filaments at Bd in some specimens of Dpl. oihonnae appears to be random and most likely represents the morphological variability of this species. We also obtained DNA sequences of 18S rRNA, 28S rRNA, ITS-2, and COI of Dpl. oihonnae from the neotype locality for comparison with the sequences available in GenBank, which showed low genetic differences between the neotypic population and specimens from other localities. Therefore, we decided to establish our specimens from Merok as neotype and neoparatypes of Dpl. oihonnae. Additionally, based on morphological characters, Dpl. horningi (Schuster Grigarick, 1971) was synonymised with Dpl. oihonnae.
在本研究中，我们使用综合分类学来描述来自 Merok（挪威）模式产地的 Diploechiniscus oihonnae（Richters，1903）种群。我们发现 Dpl. oihonnae 的生命阶段和性别的体节排列公式没有差异。在一些 Dpl. oihonnae 标本中，Bd 上存在的细丝似乎是随机的，很可能代表了该物种的形态变异性。我们还从模式产地获得了 Dpl. oihonnae 的 18S rRNA、28S rRNA、ITS-2 和 COI 的 DNA 序列，与 GenBank 中可用的序列进行比较，结果显示模式种群与来自其他地点的标本之间的遗传差异很小。因此，我们决定将来自 Merok 的标本确立为 Dpl. oihonnae 的模式和副模式。此外，根据形态特征，Dpl. horningi（Schuster Grigarick，1971）被同义化为 Dpl. oihonnae。
