摘      要：Tenthredo bicuspis Liu Wei sp. nov. and T. biminutidota Liu Wei sp. nov. are described from China. Tenthredo bicuspis is similar to T. amurica Dalla Torre, 1894 from Siberia in Russia but differs in the pterostigma yellow brown, the upper inner orbits, temple, pronotum, tegula, mesoscutellum and mesepisternum with distinct white maculae, the mesoscutellum strongly elevated with two obtuse peaks, the dorsum of head impunctate, the dorsum of thorax and mesopleuron shiny, the supraantennal tubercles strongly elevated with the posterior end abruptly cut off. Tenthredo biminutidota is similar to T. flavobrunneus Malaise,1945 but differs in the postocellar area about 1.5 times as broad as long, the lateral furrows distinctly divergent backwards; the black macula on dorsum of head very large and almost touching the eye or nearly so, the supraantennal tubercles largely black and evenly merging with frontal walls; the mesoscutellum and mesepisternum not strongly elevated with a low peak; each abdominal tergite with a narrow basal black band and a pair of black dots laterally; the female hypopygium with a large middle process and serrulae hardly elevated.
