| abstract | Two new species of Achipteriidae, Dentachipteria sidorchukae sp. nov. from moss and Cubachipteria clavata sp. nov. from soil in Yunnan Province, Southwest China are described and illustrated. Dentachipteria sidorchukae sp. nov. is most similar to Dentachipteria ringwoodensis but can be distinguished from the latter by the following characterstics: 3 or 4 pteromorphic denticles, seta in thickened, not reaching distal parts of lamellae. Cubachipteria clavata sp. nov. is most similar to Cubachipteria maxsellnicki, but can be distinguished from the latter by the following characterstics: seta in setiform, slightly barbed, not reaching distal parts of lamellae, seta le smooth, inserted ventrally on the lamellae. |
