| abstract | Two new species of Achipteriidae, Campachipteria (Campachipteria) lushuiensis sp. nov. from Yunnan Province, and Campachipteria (Triachipteria) ludingensis sp. nov. from Sichuan Province, Southwest China are described and illustrated. Campachipteria (C.) lushuiensis sp. nov. is most similar to Campachipteria (C.) uenoi, however, it can be distinguished from the latter by the areae porosae Aa, A1, A2 larger, distance Aa–lm shorter than one-half of the size of Aa, areae porosae consisting of fine and dense punctures, seta le thickened, smooth and beyond the tip of lamellae. Campachipteria (T.) ludingensis sp. nov. is most similar to Campachipteria (T.) truncata, however, it can be distinguished from the latter by the seta in smooth and short than one-half of lamellae, seta le minute, inserted dorsally on the lamellae and not reaching the distal parts of lamellae. |
