摘要

根据所有模式材料和其他标本，重新研究了鄂霍次克海特有的三个标称种，即 Lycodes ygreknotatus Schmidt in Taranetz, 1937、L. microlepidotus Schmidt, 1950 和 L. fulvus Toyoshima, 1985。ygreknotatus 的初级异名，因为这些分类群之间没有发现明显的形态差异。Lycodes ygreknotatus 被重新诊断。它在脊椎骨数量和鳞片覆盖密度方面都表现出明显的地域差异性。观察到的变异可能是由于其广泛分布区不同地区的环境温度差异造成的。

On the systematics of three eelpout species (Teleostei: Zoarcidae: Lycodes) endemic to the Sea of Okhotsk

Three nominal species of eelpouts endemic to the Sea of Okhotsk, specifically Lycodes ygreknotatus Schmidt in Taranetz, 1937, L. microlepidotus Schmidt, 1950, and L. fulvus Toyoshima, 1985, are reinvestigated based on all type materials and additional specimens. The latter two species are recognised as junior synonyms of L. ygreknotatus, as no significant morphological differences were found among these taxa. Lycodes ygreknotatus is rediagnosed. It exhibits significant geographic variability in both the number of vertebrae and the density of scale cover. The observed variability can likely be attributed to differences in environmental temperatures across different parts of its extensive distribution range.

期刊介绍： Zoosystematica Rossica is an international journal for publication of papers on any aspects of systematic zoology, in all groups of animals, both extant and fossil, from all over the World. The journal is published in English and focuses on the descriptions of new taxa, revisions and reviews, nomenclature, theories and methods of taxonomy and phylogeny, interesting new faunal records, catalogues and checklists, identification keys, phylogenetic relationships and zoogeography. Faunistic articles are published in a limited way and only if they contain new records for large geographical regions and are important for zoogeography or taxonomy.
