The types are deposited in the Entomological Museum of Ghina Agricultural University, Beijing. Syneches ancistroides sp. nov. （ Figs. 1-2） The new spedes is somewhat similar to S. fujianensis Yang et Yang from Fujian in the hypandrium with a large apical incision, but it can be separated from the latter by the antenna black, the tibiae brownish with the black extreme base and yellow apex, and the aedeagus with the long apico-lateral process. In S. fujianensis, the antenna is brownish yellow, the tibiae are yellow, and the aedeagus has the short apico-lateral process （Yang ＆ Yang, 2004）. Holotype male, Guangdong, Ruyuan, Nanling, Xiaohuangshan, 1 500 m, 9 May 2004, WANG Meng-Qing （CAU）. Etymology. The specific name refers to the hook- like apico-lateral process of the aedeagus. Syneches nankunshanensis sp. nov. （Figs.3-4） The new species is somewhat similar to S. Yang, Yang et Hu from Hainan in the wing hyaline with R4＋5 and M1 nearly parallel apically, but it can be separated from the latter by the femora blackish with tips of the fore and mid femora yellow and the wing without the distinct stigma. In S. apiciflavus, the femora are yellow with the blackish extreme tips, and the wing has a short and wide stigma （Yang ＆ Yang, 2004）.

Syneches shumuyuanensis sp. nov. （Figs.5-6） The new species is somewhat similar to S. latus Yang et Grootaert from Guangdong in the shape of tergite 9, but it can be separated from the latter by the antenna black, the femora black with yellow or brownish yellow tips, the apico-ventral comer of tergite 9 acute, and the short apico-lateral process of the aedeagus.
