Metopina sagittata Liu

( Figs 23 –28)

Metopina sagittata Liu, 1995: 485 .

The type series was from China (Guangzhou, Guangdong and Guangxi). In the original description the costal index of the female was given as 0.36, and this was repeated by Liu (2001). However, this is clearly at odds with his figure of the wing in the latter publication and the costal index of a paratype (see below) is 0.56–0.57. The specimen from Korea is a little paler than the females from China and the costal index is 0.52–0.53. Its abdominal tergites 3–6 are as Figs 24–26 compared with Liu’s figure ( Fig. 23 ). From his figure the length to breadth ratios of T3 and T4 are 1.5: 1 and 0.9: 1. For the Korean specimen these ratios are 1.1: 1 and 0.9: 1. However, the difference for T3 is probably not significant as the front margin of the tergite is not only less well defined than the other margins but is frequently partly obscured by partial overlap by the posterior edge of segment 2. Also there is evidently some variation as Liu gives the wing length as 0.94–1.0 mm. For the Korean specimen the length is 1.10 mm.
