| The tribe Opatrini, belonging to the family Tenbrionidae, is of great economic importance. Since Laporte de Dastelnau set up the tribe in 1840, known 82 genera with about 900 species are occupied. And its studying history is more than 160 years, now having entered a stage of systematic research. China is vast in territory and has a remarkably diverse fauna, but the study about this field has fallen far behind. The Opatrini in China is almost called to be described by the foreign scholar, only 1 new genus with 8 new species are found by the native scholar. At present, there is still no completely of systematic study on the tribe Opatrini in China, and then it will directly affect to the progress of the whole world. So in order to change this situation, the classification study on this field was carried out. This paper is composed of the general part and the classification part.In the general part, the classificatory station, Phologenitic classification, Summary of classification research, Material and methods, Morphological characters, Biology and Economical importance are introduced in detail.Using the Hennig 86 program makes a cladistic analysis of 14 genera from China. The cladogram shows that the Opatrini of 14genera in China is not a monophyly, Mesomorphus is a monophyly, and another monophyly is composed of others 13 genera.And according to the faunal analysis, We can conclude that Opatrini in China is mainly distributed in Palaearetic Region, hi which the number of genera makes up 59.1% (13 genera) of the total, including 50% (11 genera) in Middle Asian Subreahn, which Combined with distribution of this tribe in the world, So it isproposed that the Middle Asian Subrealm can be viewed as the core of distribution. Most of genera distributed in limited area, only Gonocephalum distributed in extensive area. Majority of the species are amassed in Mongolia-Xinjiang region and south-China region.In the classification part, 22 genera with 149 species in China are described, and documents, synonyms, distributions of each species are listed. Keys of genera and species are drawn up, its morphological characters are depicted, and photographs are taken. During this study, 4 species new to science are found. Furthermore, 2 genera 16 species are reported for the first time from China, and 3 new synonyms are found.1. New species:Melanesthes (Opatronesthes) gigas sp. nov. ( Table 1)Holotype: , Ningxia: Zhongwei, 1985-IV-21, Ren Guo-dong; Paratypes: 1 ,3 , the same as holotype.The new species is similar to Melanesthes (Opatronesthes) punctipennis Reitter, 1889 with the following differences:Melanesthes (Opatronesthes) granulates sp. nov.Holotype: , Qinghai: Xining Shi (2040 m), 1995-W-11, Ren Guo-dong.The new species is similar to Melanesthes (Opatronesthes) monatroides Reichardt, 1936 with theMonatrum placosalinus sp. nov.Holotype: 6 , Neimenggu: Baotou, 1991-VH-7, Ren Guo-dong; Paratypes -. 66 5,2? 2 , the same as holotype; 45 5,1$, Xilin Gol Meng, 1987- 1V-4, Guo Chao-yuan.The new species is similar to Monatrum mongolieum Kaszab, 1967 with the following differences:Eumylada glandulosa sp. nov.Holotype: 5, Neimenggu: Alxa Zuoqi, 1987-VB-27; Paratypes: 8 5 6,109 $ , die same as holotype; 135 6 , 302 $ , AlxaYouqi, 1988-VI-9; 166 6 , 262 2 , AlxaYouqi, 1992-Vtt; Ren Guo-dong. The new species is similar to Eumyladapunctifera (Reitter, 1889) with the following differences:All the type specimens are deposited in the Museum of Hebei University...
