This is the first report on the occurrence of stephanofilarial sore on the teats of cows in the Nansei (South western) Islands, Japan, and on the taxonomical position of etiological parasites. Stephanofilaria worms were collected from cutaneous lesions of affected teats of cows in such proportion that the sex ratio of worms might be one male to three females. Morphological and anatomical observation was made on parasites suspended in lactophenol and by the scanning electron microscope. As a result, these parasites belonged to the same species as Stephanofilaria sp. Kono, 1965, which was previously reported to cause a strange type of dermatitis on the muzzle of cattle in the Nansei Islands. The description of Stephanofilaria sp. by Kono was reviewed. Subsequently, detailed comparison was made between those parasites and the other known species of the genus Stephanofilaria. It led to the establishment of a new species called S. okinawaensis Ueno and Chibana, 1977 after the name of the enzootic area.
这是关于日本西南诸岛奶牛乳头出现丝虫性溃疡以及病原性寄生虫分类地位的首份报告。从患奶牛乳头的皮肤损伤处采集到丝状线虫，其雌雄比例约为1:3。对悬浮在乳酸酚中的寄生虫以及通过扫描电子显微镜进行了形态学和解剖学观察。结果表明，这些寄生虫与1965年报道的曾引起西南诸岛牛口鼻部一种奇特性皮炎的丝状线虫属（Stephanofilaria sp. Kono）为同一物种。对Kono所描述的丝状线虫属进行了回顾。随后，将这些寄生虫与丝状线虫属的其他已知物种进行了详细比较。最终，根据该地方病流行区的名称，建立了一个名为冲绳丝状线虫（Stephanofilaria okinawaensis Ueno and Chibana, 1977）的新物种。
