Description.

Measurements. BL: 4.56-6.06; FL: 2.98-3.39.

Female. Tergite VIII (Fig. 4F) with wide and very deep, acute triangular medio-apical emargination, one very long, strong, black seta at apical margin at each side of medio-apical ernargination. Sternite VIII (Fig. 4G) broadly emarginate eat the middle of posterior margin and bearing six or seven yellowish cilia at the latero-posterior parts.

Distribution.

China: Fujian, Zhejiang.

Remarks.

The species was previously described based on male specimens from Fujian Prov., and this is the first record of its female. It is very similar to Derops smetanai Schülke, from Fujian ( Schülke 2003: 467, figs 1-9). Males may be readily distinguished by the shape of sternite VII emargination and by evenly narrowed, slightly bend to obtuse apices of aedeagus lateral lobes. Females may be easily distinguished by the shape of tergite VIII emargination.
