据报道，日本有约160种密生虫。其中，只有18种已报告的广泛的群岛的南西（西南）群岛，即使这个暖温带至亚热带地区应该有一个密集的动物区系一样丰富或比周围的日本主要岛屿。本文描述了南西群岛附近大陆架52-334米深度范围内的五种密生虫。Rhopalorhynchus tenuissimum（Haswell，1884）是日本本属和种的第一个记录，Pycnogonum tenue斯莱特，1879是南西岛地区的一个新记录;我们报告了这些种的一些以前未被认识的分类特征。我们描述了新种Endeis levientia，Hedgpethia elongata和Pycnogonum spatium。
About 160 species of pycnogonids have been reported from Japan. Among these, only 18 species have been reported from the extensive archipelago of the Nansei (southwest) Islands, even though this warm-temperate to subtropical region should have a pycnogonid fauna as rich as or richer than that surrounding the Japanese main islands. We provide descriptions for five species of pycnogonids collected from depths of 52-334 m along the continental shelf adjacent to the Nansei Islands. Rhopalorhynchus tenuissimum (Haswell, 1884) is the first record of this genus and species for Japan, and Pycnogonum tenue Slater, 1879 is a new record for the Nansei Island region; we report some previously unrecognized taxonomic characters for these species. We describe as new species Endeis leviseminentia, Hedgpethia elongata, and Pycnogonum spatium.
