The species of Tenthredo simlaensis group is briefly discussed. The diagnosis of the species group and the differences between T. simlaensis group and T. pedicellus group are also discussed. Two newspecies of Tenthredo simlaensis group from China are described： Tenthredo pseudoformorsula Wei et Shang,sp. nov . and Tenthredo transversiverticina Wei et Shang, sp. nov. Tenthredo melanosternum Saini Vasu,1999 and Tenthredo segrega Konow,1908 are recorded firstly from China. Tenthredo rubrocaudata Takeuchi,1936,syn. nov .,is a new junior synonym of Tenthredo eburata Konow,1900. Tenthredo pseudoformorsula Wei et Shang,sp. nov. （Figs 1-10） This newspecies is similar to Tenthredo formosula Wei,2002 but differs from the latter species in scape yellow green in both sexes,the upper inner orbit in female with a distinct green stripe; the mesepisternum entirely yellow green; the lateral process of female sternite 7 short and broad; the middle serrulae weakly elevated; the lateral black stripes on male tergites not narrower than the middle green stripe; the apex of penis valve round. In Tenthredo formosula,scape black in both sexes,the upper inner orbit in female entirely black; the ventral half of mesepisternum black; the lateral process of female sternite 7 longer; the middle serrulae much more elevated; the lateral black stripes on male tergites much narrower than the middle green stripe; the apex of penis valve distinctly tapering.

Etymology . The specific epithet is composed of pseudo-and formosula,as the newspecies is very similar to T. formosula in body colour but much different in genitalia. Tenthredo transversiverticina Wei et Shang,sp. nov. （Figs 11-17） This new species is close to T. simlaensis Cameron, 1899 but differs from the latter in the postorbit, supraclypeal area,supraantennal tubercles,postocellar area,ventral corner of pronotum ,prescutum black; the yellow green band on mesepisternum not reaching anterior margin; the abdominal tergites 1-8 each with a small triangular middle spot which is much narrower than lateral black stripes; the postocellar area 2. 5 times as broad as long; the third antennomere 1. 1 times as long as fourth antennomere; the mesepisternum densely microsculptured without distinct punctures, mat; the mesonotum minutely punctured and with distinct microsculptures between punctures; mesoscutellum with low transverse ridge; the posttergite 2 times as broad as long and about 2 times diameter of lateral ocellus in length; the middle serrulae weakly elevated. In T. simlaensis Cameron a broad stripe on postorbit,supraclypeal area,supraantennal tubercles, postocellar area, ventral corner of pronotum ,posterior of prescutum yellowish green; the yellow green band on mesepisternum broadly reaching anterior margin; the abdominal tergites 1-8 each with a broad quadrate middle macula which is as broad as lateral black stripes; the postocellar area 1. 6 times as broad as long; the third antennomere 1. 3 times as long as fourth antennomere; the mesepisternum with large and sparse punctures,without microsculpture,shiny ; the mesonotum sparsely punctured and without microsculptures between punctures; mesoscutellum roundly elevated, without transverse ridge; the posttergite 3 times as broad as long and about 1. 3 times diameter of lateral ocellus in length; the middle serrulae strongly elevated.
