Two new species of the genus Teulisna Walker, 1862 (Lepidoptera: Erebidae: Lithosiina) are described from India: Teulisna (Cossa) breveprocessa sp. nov. (from Western Ghats of Kerala) and T. (Tegulata) nicobara sp. nov. (from Great Nicobar Island). The former is diagnosed with its close congeners in subgenus Cossa Walker: T. (C.) ruma (Swinhoe, 1890 1889), T. (C.) munnara Volynkin, 2023, T. (C.) basigera (Walker, 1865) and T. (C.) inducta (Walker, 1865), whereas, the latter is diagnosed with T. (Tegulata) chiloides chiloides (Walker 1862). Teulisna (Poikilothosia) sayinyingpo Huang, Volynkin & Černý, 2025, from Arunachal Pradesh, is a new record to India.
