Abstract (in english)
   The genus Satonius is revised. Three new species are described from China: Satonius schoenmanni sp. n., S. stysi sp. n., and S. wangi sp. n. Two additional new species are left undescribed pending the collection of complete specimens and males, respectively. Metathoracic wing venation of S. stysi sp. nov. is shown to differ from the remaining Myxophaga in the presence of the bifurcation of AA3+4, which updates the venation groundplan of the suborder. Anterolateral spine-like projection of the metaventrite and the increased number of apical setae on parameres are defined as adult autapomorphies of the genus. Larvae of S. stysi sp. nov. are described and compared with the larvae of the Japanese S. kurosawai. Characters shared by larval Satonius and Ytu are supposed as parallel adaptations for the larval environment. Interspecific wing polymorphism of Satonius is briefly discussed and possible reasons of the wide distribution of the apterous S. kurosawai are hypothesized.
