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.
