【Abstract】 Two new specie Apataniana spinosa sp. nov. (Apataniidae) and Astratodina helanensis sp. nov. (Limnephilidae) are described and illustrated from Helan Mountain,Inner Mongolia of China. Type specimens are deposited in the Insect Collection of Nanjing Agricultural University. 1 Apataniana spinosa Yang et Tao,sp. nov. (Figs 1-5) The new species is allied to Apataniana cornuta Ivanov,1991,from Eastern Kazakhstan,in sharing similar venation pattern of hind wing and deeply incised distal segment of inferior appendage in male genitalia. They differ from the other members of this genus and can be a separate species-group. The new species differs from the latter in male genitalia in:1) preanal appendages two times as long as segment Ⅹ; evenly curved inwards,with rounded apices crossed each other in dorsal view (not quite as long as segment Ⅹ; each curved in elbow like,with apico-inner angle stretched in point in dorsal view in Apataniana cornuta); 2) distal 2/3 narrowed in vase like (broad oval in Apataniana cornuta); 3) distal segments of inferior appendages with dorsal branches each bearing two or three stout,black spines basally ( simple,without any spine at base in Apataniana cornuta). Holotype ♂,Inner Mongolia,Helan Mountain,Yao-Ba (38.7° N,105.8° E; alt. 2 243 m),8 Aug. 2010,collected by LIANG Shao-Guang. Paratypes:2♂♂,28♀♀,same data as holotype;2♂♂,15♀♀,Inner Mongolia,Helan Mountain,Hei-gou (39.2° N,106.0° E; alt. 1 700 m),4 Aug. 2010,collected by LIANG Shao-Guang; 1♀,Inner Mongolia,Helan Mountain,Xiaosongshan,Baitugou (39.1° N,106.0° E; alt. 1 907 m),14 Aug. 2010,collected by LIANG Shao-Guang. Etymology. The Latin word "spinosa" means "thorny",in reference to distal segments of inferior appendages with dorsal branches each bearing two to three stout,black spines. 2 Astrotodina helanensis Yang et Jia,sp. nov. (Figs 6-9) The new species is not similar to any members of the genus. It can be distinguished from all other species in male genitalia by:1) intermediate appendages mandible like with blunt apices not divided; 2) inferior appendages broad and short,with broadly rounded apical margins in lateral view,its bases completely fused with segment Ⅸ; 3) parameres each with apex shortly forked,in ventral view,with its narrow ventral margins sub-parallel to each other and appressed near the middle,each with apex directed mesad. Holotype ♂,Inner Mongolia,Helan Mountain,Xiaosongshan,Baitugou (39.1° N,106.0° E; alt. 1 907 m),14 Aug. 2010,collected by LIANG Shao-Guang. Etymology. The specific name is derived from the type locality Helan Mountain,Inner Mongolia Autonomous Region.更多还原
