两个大型捕食性唾液水蚤标本 Blanchard，1897采自日本琉球群岛的冲绳岛，代表了冲绳岛本种的第一记录。描述了这些标本的外部和内部形态，以及同样在琉球群岛的Amami-Oshima岛上的另外两个日本根结线虫标本。来自冲绳岛的两个日本沼虾标本与来自大岛县的两个标本(K2P距离=0%)的COI序列没有差异。这表明，日本沼虾是在这两个岛屿中的一个或两个岛屿上引进的物种。
Two specimens of the large, predaceous salifid leech Mimobdella japonica Blanchard, 1897 were collected from Okinawajima island, Ryukyu Islands, Japan, representing the first record of this species from Okinawajima. A description is provided of the external and internal morphology of these specimens and two additional specimens of M. japonica from Amami-oshima island, also in the Ryukyu Islands. COI sequences showed no difference between the two specimens of M. japonica from Okinawajima and the two specimens from Amami-oshima (K2P distance=0%). This suggests that M. japonica is an introduced species in one or both of these islands.
