The genus Kapsa Dworakowska is redescribed and a new subgenus Kapsa (Rigida) Cao & Zhang is established to include thirteen species, a key to males of the subgenus is provided, and eight new species from China are described and illustrated: Kapsa aculeiformis, K. apicispina, K. brevis, K. explanata, K. furcata, K. imminuta, K. mnegaprocessa and K. serrata spp. nov.. Based on detailed study of previously described species, Kapsa yanheensis Song & Li, 2012 is considered a synonym of Tautoneura albida (Dworakowska, 1970). Four species previously placed in Kapsa are transferred to Tautoneura Anufriev: Tautoneura decorata (Dworakowska, 1981), T. diasonica (Chiang & Knight, 1990), T. elscinta (Chiang & Knight, 1990) and T. puerensis (Song & Li, 2012).
