摘　　要：描述采自内蒙古贺兰山自然保护区的毛翅目2新种,即多刺闭室沼石蛾Apataniana spinosa Yang et Tao,sp.nov.和贺兰光突沼石蛾Astratodina helanensis Yang et Jia,sp.nov.。模式标本保存于南京农业大学昆虫标本馆。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 m
