本文描述了采自日本西南部琉球群岛西表岛泥滩上的红树林根表面的一种新种-Teleotanais madara sp. nov.。这是第一个记录任何teleotanaid物种来自西北太平洋。Teleotanais madara与T. gerlachi和T. gerlachi sensu Sieg（1976），但不同之处在于第2触角条上有中内单刚毛，尾足基条上有两个腹侧刚毛，螯足固定指上有一个或两个腹侧单刚毛，第1肢节上的腹远侧单刚毛长度为肢节宽度的一半，第4-6肢节的指-甲有节。我们还提出了部分的核苷酸序列的细胞色素c氧化酶亚基I（COI）基因在T。madara用于未来的DNA条形码和基因组学。
We describe Teleotanais madara sp. nov. from the surfaces of mangrove roots on mudflats at Iriomote Island, Ryukyu Islands, southwestern Japan. This is the first record of any teleotanaid species from the northwestern Pacific. Teleotanais madara resembles T. gerlachi and T. gerlachi sensu Sieg (1976), but differs in having a mid-inner simple seta on antennular article 2, two ventral setae on the basal article of the uropod, the chelipedal fixed finger with one or two ventral simple setae, ventrodistal simple setae on the perepod-1 merus being half as long as the width of the merus, and the dactylus–unguis of pereopods 4–6 articulate. We also present the nucleotide sequence for part of the cytochrome c oxidase subunit I (COI) gene in T. madara for future use in DNA barcoding and phylogeny.
