Polypedilum （Tripodura） cypellum sp. nov. from Xishan Island, Zhejiang Province is described. The new species is most similar to P. （T.） harteni Andersen ＆ Mendes, 2010 morphologically. It can be distinguished from the known species in this genus by the goblet-shaped superior volsella. Diagnostic characters of the male imago （wing, fore tibial apex, hypopygium and superior volsella） are illustrated.
One new species from China, Phasia xuei sp. nov., is described and illustrated. A modified key to the Phasia barbifrons-group is provided. The types are deposited in the Insect Collection of Shenyang Normal University （SYNU）.
A new species of non-biting midge（Diptera： Chironomidae）, Microtendipes brevissimus sp. nov.,based on a male from Gutian Mountain in Zhejiang Province is described and illustrated. This new species is characterized by a short anal point, median volsella absent and tergite IX without median seta.
Dicrotendipes weiqiangensis sp. nov. from Xianju National Park, Zhejiang, China is described and nominated. This new species is morphologically most similar to D. nudus Qi, Lin Wang, 2012. It can be distinguished from the known species in the genus by R_（4＋5） without seta and the shape of the superior volsella, which is semi-triangular viewed dorsally and spherical viewed laterally. Diagnostic characteristics of the male imago（e.g., wing, hypopygium, anal point and superior volsella） are illustrated. A key to the males of Dicrotendipes in China is also provided.
Stenochironomus xianjuensis sp. nov. from Xianju National Park, Zhejiang Province, China, is described. The new species is morphologically similar to S. koreanus Borkent, 1984. It can be distinguished from known species in the genus by the following combination of characters： wing with two dark spots surrounding RM and FCu; superior volsella short and small, spatulate, with 4 long setae; inferior volsella elongate, with 3 long setae and a slender terminal spine, posterior margin of tergite IX with 8-10 setae and 8 spines.
A new species, Polypedilum（Polypedilum） xianjuensis sp. nov. collected from the Xianju National Park, Zhejiang Province is described and illustrated. The new species is characterized by dark brown body coloration, small antennal ratio（0.60–0.88） and superior volsella without lateral seta.
