Material examined

Two females (ECNU20140914/TT34; ECNU20140907/TT35) dissected.

Dimensions

(Female, n = 3) Length, 1.20–1.33 mm; height, 0.51–0.53 mm; width, 0.33 mm.

Brief description

Female, in lateral view, both anterior and posterior ends widely rounded. Maximum height anterior of mid-length. Dorsal margin straight. Posterior area with ‘roof-tile’-like structure. In internal view, postero-ventral margin slightly sinuous. A1 seven-segmented, with Rome and Wouters organs; first segment with one dorsal seta. Natatory setae of A2 long, just reaching or slightly exceeding tips of terminal claws. Seta β on Md short and hirsute, basally inflated, tapering distally. Two large bristles on third masticatory lobe of Mx1 slightly toothed. L6 fivesegmented, two hirsute setae d present on basal segment, seta d1 slightly longer than seta d2, seta e slightly exceeding end of next segment. L7 four-segmented, three setae d present on basal segment. Both claws on UR with well-developed serration. Claw Gp equalling onehalf length of claw Ga. Seta Sa equalling three-quarters length of claw Ga. Seta Sp brush-like, with setae distally. UR attachment stout, curved stem with triangular Triebel’ s loop distally. UR attachment with strong, curved dorsal branch and thick and short ventral branch.

Distribution

This species has only been reported from South Korea ( Smith et al. 2015), and as an alien species in a botanical greenhouse in Germany ( Nagler et al. 2014). It is a new record for China.

Remarks

The seta Sp of our specimens is morphologically more similar to that of Tancypris pellucida than to that of specimens from Germany ( Nagler et al. 2014). The seta Sp on the UR of our specimens has a brush-like end ( Figure 13 View Figure 13 ), and the one from Germany is slender, and this character has not been mentioned in Korean specimens ( Smith et al. 2015).
