A new species, Typhlamphiascus tuerkayi sp. nov. (Copepoda, Harpacticoida, Miraciiidae), is described from specimens collected in the South China Sea. This new species differs from its congeners by the combined characters of the number of chitinous lamellae on the male P1, the apomorphic setal formulae of the swimming legs, and the setal number on P5. The new species is most similar to T. ovale Wells & Rao, 1987 and T. higginsi Chullasorn, 2009. It differs from the latter two species by the following features: the caudal ramus about three times as long as broad, P2 exp-3 with three outer spines, P3 enp-3 with two inner setae, P5 basoendopod in the female with four setae, P5 exopod in the female about three times as long as its greatest width, antennule of male 9-segmented, the inner edge of the basis in male P1 with eight chitinous lamellae, P5 exopod in male with four setae.
