Tanycypris centa sp. nov. Chang et al., 2012: 4, figs. 2(D–H), 3, 4.

Material examined

One female (ECNU20140914/TT36) dissected.

Dimensions

(Female, n = 3) Length, 1.10–1.30 mm; height, 0.42–0.47 mm; width, 0.36 mm.

Brief description

Female, carapace long and smooth, with brown patches. In lateral view, anterior end wider than the posterior. In inner view, postero-ventral margin obviously sinuous. First segment of A1 without any dorsal setae. Seta S p on UR slender and hirsute distally.

Distribution

This species has been reported from South Korea ( Chang et al. 2012) and Germany ( Nagler et al. 2014). It is a new record for China.

Remarks

The length of our specimens (1.10–1.30 mm) is slightly longer than other specimens found from South Korea (1.10–1.15 mm) and Germany (1.10–1.14 mm) ( Chang et al. 2012; Nagler et al. 2014). In our specimens, seta d2 on L7 exceeds the middle of the next segment and seta dp reaches the end ( Figure 14b ); whereas in South Korean specimens, these two setae only reach the middle of the next segment ( Chang et al. 2012).
