A new species of ghost shrimp, Ctenocheles sinicus, is described based on specimens recently collected from Taiwan Strait, the East China Sea, at a depth of 50 m. The new species is characterized by: the dorsally unarmed rostrum attaining one-third the length of the eyestalks; the rounded suborbital angle of the carapace; maxillipeds 2 and 3 each with a short exopod; the merus and ischium of pereopod 1 being unarmed along the lower margin; the major cheliped with fingers twice as long as the palm; the ischium of pereopod 2 armed with prominent spiniform setae along the lower margin; and the rounded anterodistal angle of uropodal exopod. The morphological differences between the new species and other congeners are discussed and a key to the species of Ctenocheles Kishinouye, 1926 is provided.
