[email protected] Abstract Arge captiva (Smith, 1874) and its allied taxa are revised and four species are recog- nized. All relevant type material was studied, except for that of Arge praesternalis Malaise, 1934. Arge macrops sp. n. (ϭArge sanguinolenta auctt., nec Mocsáry, 1909) is described and illustrated from the Primorskij Kraj, Korea and China. The following synonymy is established or confirmed for Arge captiva: Arge captiva (Smith, 1874) (ϭHylotoma captiva Smith, 1874ϭHylotoma flavi- collis Cameron, 1876 [syn. n.]ϭArge sanguinolenta Mocsáry, 1909 [syn. n.]ϭArge kolthoffi For- sius, 1927 [syn. n.]ϭArge captiva rufoscutellata Takeuchi, 1927). Arge siamana Togashi, 1988, is removed from synonymy with A. captiva. A little known species, A. praesternalis, is treated as a valid species. Key words : Argidae, Arge captiva group, Arge macrops, new species, new synonymy. The sawfly genus Arge (Hymenoptera, Argi- a median carina and the nearly glabrous outer dae) is represented by more than 300 described margins of the wings. The larvae of A. rejecta are species in the world, including about 120 species known to feed on Rubus spp., whereas those recorded from eastern Asia (Gussakovskij, 1935; of A.
