Abstract: Genus Aconias Cameron, 1904 Aconias Cameron, 1904: 345. Type species: Aconias spinitarsis Cameron, 1904. Monotypic. Three species, Ac. albitarsis (Uchida, 1936), Ac. concavopropodeonus (Uchida, 1952), and Ac. tarsatus (Bridgman, 1881), have been recorded from Japan. Uchida (1952) notes that the Ac. albitarsis (Uchida, 1936) and Ac. concavopropodeonus (Uchida, 1952) by the character states of propodeum, while this difference between both species is intraspecific variation. Sheng & Sun (2008) provided the key for world species and Ac. albitarsis is separated from Ac. tarsatus (Bridgemann, 1881) by the coloration of face (black in Ac. albitarsis; white in Ac. tarsatus) and hind tibia (black with pale coloured base in Ac. albitarsis; reddish brown with black apex in Ac. tarsatus). But the face of Ac. tarsatus is misdescription and the coloration of hind tibia of Ac. tarsatus is intraspecifically varied and the range of variation overlapped with Ac. albitarsis. Thus, I conclude that Ac. albitarsis is a junior synonym of Ac. tarsatus (syn. nov.). In this study, I newly describe two new species below. Both species are identified as this genus by Townes (1970) and are well accorded the character states of this genus. While the surface sculpture of hind femur and the remarkably long setae on it are largely differed from other species. The generic position of two new species should be reanalysed by future study.
