Two new species of the genus Tillicera Spinola, 1844 from China are described and illustrated: Tillicera sensibila sp. n. form Yunnan and Tillicera wenii sp. n. from Taiwan. Tillicera bibalteata Gorham, 1892, T. hirsuta (Pic, 1926) and T. michaeli Gerstmeier & Bernhard, 2010 are newly recorded from China. Tillicera auratofasciata (Pic, 1927) is newly recorded in some provinces of China. A key to species of the genus from China is provided. Relationships between species are discussed with emphasis on characters of male phallus, female internal reproductive organs and pit-like sensilla in male terminal antennomere, which is discovered in Tillicera for the first time. The present generic definition of Tillicera is discussed as well. Photos of terminalia of the previously known species are also provided for comparison.
