在日本琉球群岛的淡水溪流中发现了三种博福特鰕虎鱼，经形态学和线粒体DNA序列鉴定，它们是不同的种类。虽然以前在日本已知两种（S。roxasiHerre 1936和S. AmpluvinculusChen，Shao，and Fang 1995），分类学需要修订。为了鉴别这些种，对S. marmoratus（Peters 1868），S. bruyniside博福特1912和S. roxasi，最初描述来自菲律宾和印度尼西亚，在这里进行了检查和重新描述，因为在最初的描述中提供的关于其诊断特征的信息相对较少。这3个日本种被鉴定为S. ampluvinculus，S. marmoratus和一个新物种。它们彼此区分，并从它们的同类的身体的带状图案，标记的胸鳍，色素图案的腹面的头部和腹鳍，身体的深度在腹鳍的起源，肛门前的长度，和胸鳍射线计数。虽然新种一直被认为是S. roxasiin以前的出版物，我们表明，它实际上不是S。roxasis和它也不同于所有其他命名物种的frommatogobius。这是一个新种，S.忍者此外，这也是S.日本的大理石花纹。
Three species ofSchismatogobiusde Beaufort 1912, distinguished by their morphology and mitochondrial DNA sequences, were found in freshwater streams in the Ryukyu Archipelago, Japan. Although two species were previously known from Japan (S. roxasiHerre 1936 andS. ampluvinculusChen, Shao, and Fang 1995), the taxonomy needs to be revised. To identify these species, the holotype morphology ofS. marmoratus(Peters 1868),S. bruyniside Beaufort 1912, andS. roxasi, originally described from the Philippines and Indonesia, were examined and re-described here, because relatively little information about their diagnostic characters was provided in the original descriptions. The three Japanese species were identified asS. ampluvinculus,S. marmoratus, and a new species. They were distinguished from each other and from their congeners by the banding pattern of the body, markings on the pectoral fins, pigment patterns on the ventral surface of the head and pelvic fin, body depth at the pelvic-fin origin, pre-anal length, and pectoral-fin ray counts. Although the new species had been regarded asS. roxasiin previous publications, we show that it is actually notS. roxasiand that it also differs from all other nominal species ofSchismatogobius. This is described as a new species,S. ninja. Additionally, this is the first record ofS. marmoratusfrom Japan.
