| The subfamily Alleculinae, belonging to the family Tenbrionidae, is of great economic importance. There are 3 tribi, 159 genera and 2795 species belonging to Alleculinae in the world and 2 tribi, 17 genera and 157 species are distributed in China. It is a remarkably diverse fauna in China, but the study on this field has been fallen far behind. The species of Alleculinae in China are almost norminated and described by foreign scholars, only 9 new species are found by native scholars. Nowadays there is still no completely systematic study of the Alleculinae in China. In order to change this situation, the classification study on this field was carried out. This paper is composed of the general account and the classification account.In the general account, status of the classification and hierarchy, review of classification research, material and methods, morphology, biology and economical importance, phylogenetic relationship, faunal composing and distribution are introduced in detail.In the classification account, 2 tribi, 13 genera with 141 species in China are recorded, and documents, synonyms, distributions of each species are listed. Among them, 89 species are depicted in morphological characters, which figures and photos are followed. Keys to genera and species are drawn up. During this study, 9 new species are found. Furthermore, 1 genus and 4 species are reported for the first time from China, and 1 new synonym is found.1. New species: 1.1 Cteniopinus brevithoracus sp. nov.Holotype , Mt. Gaoligong (26.31?N, 98.86?E; 1950m alt.), Fugong Country, Yunnan Prov., 27 June, 2000, coll. LIANG Hong-Bin. Paratype: 1 , same data as the holotype.Diagnosis. This new species can be recognized mainly by the following characters with C. nigritarsis Borchmann, 1930 (distributed in Korea): the former femur yellow; the length of pronotum shorter than the width evidently; 1st to 3rd segments of antenna yellow; terminal segment of maxillary palpus with the length of upside margin 1.3 times as that of downside one. Whereas in the latter femur black; the length of pronotum nearly equal to the width; antenna black completely; terminal segment of maxillary palpus with the length of upside margin 2.2 times as that of downside one.Etymology. This new species is named after pronotum is somewhat broad.1.2 Cteniopinus nigrocapitis sp. nov.Holotype Mt. Gaoligong (26.3 N, 98.86?E; 1950m alt.), Fugong Country, Yunnan Province, 27 June, 2000, coll. LIANG Hong-Bin.Diagnosis. This new species can be recognized mainly by the following characters with C. potanini Heyd, 1889 (distributed in Gansu Province and Sichuan Province of China): the former body length 8-9mm; the length of pronotum shorter than the width evidently; terminal segment of maxillary palpus with the length of upside margin 1.4 times as that of downside one; ventral view of body yellow to brown. Whereas in the latter body length 11-14mm; the length of pronotum nearly equal to the width; terminal segment of maxillary palpus with the length of upside margin 2.6 times as that of downside one; ventral view of body black.Etymology. This new species is named after head is black.1.3 Cteniopinus nigroventrus sp. nov.Holotype Jiangjin, Chongqing, 21 May, 2001, coll. WANG Hai-Jian. Paratypes: 1 , same data as the holotype.Diagnosis. This new species can be recognized mainly by the following characters with C. hypocrita (Marseul, 1876) (distributed in Japan and east of China): the former maxillary palpus black; pronotum wholly bordered with between red and brown margin except the frontal part of lateral margin; coxa black; abdomen black. Whereas in the latter 1st segment of maxillary palpusyellow, the 2nd brown, the 3rd deep brown; pronotum wholly bordered; coxa yellow; abdomen dark red.Etymology. This new species is named after abdomen is nearly black.1.4 Cteniopinus rubipes sp. nov.Holotype , Mt. Yujun (3000m alt.), Kangding Country, Sichuan Province, 6 August, 1999, coll. REN Guo-Dong. Paratypes: 2 , same data as the holotype.Diagnosis. This new...
