1B1687999728FFF598B2082042F4FA0B.taxon	discussion	Remarks: The new species belongs to the scalaenum or the unifascum group regarding the similar wing spots pattern, however, in the new species, anal point without obvious lateral projections and superior volsella pad-like, covered with microtrichiae and several strong setae. The new species is closely related to P. (T.) asoprimum Sasa & Suzuki from Japan but it is separated from the latter by following characters: superior volsella roughly quadrangular in asoprimum, slender and slightly curved in present new species; the spot on cell r 4 + 5 near to vein RM in asoprimum, distal to vein RM in present new species. The new species resembles P. (T.) japonicum (Tokunaga), the differences see the following key.	en	Chen, Jinxian, Zhang, Ruilei (2021): Two new species of subgenus Tripodura Towns (Diptera, Chironomidae, Polypedilum) from Oriental China.

1B168799972AFFF398B20B0B4316FA68.taxon	discussion	Remarks: The new species probably belongs to the griseoguttatum group, but without centre patch in cell bm area. In Asia, it resembles Japanese species P. (T.) sagittiferum in wing markings pattern and sculptural pattern of anal point (Tokunaga, 1938). The new species distinguishes the latter by superior volsella and inferior volsella with fewer setae, strongly developed lateral projections to each side of the anal point. Also the new species is very close to P. (T.) jianfengense Song & Wang from China but easily differs from it by having more spots in wing.	en	Chen, Jinxian, Zhang, Ruilei (2021): Two new species of subgenus Tripodura Towns (Diptera, Chironomidae, Polypedilum) from Oriental China.
