Abstract
A new species of Zapada Ricker, 1952, Zapada kondratieffi sp. nov. from central Sichuan Province of China is described and illustrated, which represents the first record of the genus in China. The new species is characterized mainly by the presence of five simple cervical gills, vestigial inner paraproct lobe, and absence of paraproct spines. The preliminary molecular phylogenetic analysis using COI sequences recovered the relationship among eight species of Zapada and supports the close relationship between Z. kondratieffi and Zapada frigida (Claassen, 1923).
