Four new species of the genus Gasteruption Latreille, 1797 (Hymenoptera: Evanioidea: Gasteruptiidae: Gasteruptiinae) are described from China. Three are from Shaanxi (NW China; G. granulatum Tan & van Achterberg, sp. nov., G. pedion Tan & van Achterberg, sp. nov., and G. reductum Tan & van Achterberg, sp. nov.) and one from S China and Ningxia (G. kexinae Tan & van Achterberg, sp. nov.). Eleven species are newly recorded for Shaanxi (G. abeillei Kieffer, 1912, G. amoyense Pasteels, 1958, G. bimaculatum Pasteels, 1958, G. corniculigerum Enderlein, 1913, G. latitibia Zhao, van Achterberg & Xu, 2012, G. minutum (Tournier, 1877), G. nigritarse (Thomson, 1883), G. parvicollarium Enderlein, 1913, G. sinarum Kieffer, 1911, G. subtile (Thomson, 1883) and G. brevicuspis Kieffer, 1911). The newly-recorded species and the new species are keyed and illustrated. Two new synonyms are proposed: G. rufescenticorne Enderlein, 1913, with G. japonicum Cameron, 1888, syn. nov. and G. oriplanum Kieffer, 1911, with G. minutum (Tournier, 1877), syn. nov.
