 Triatomani, the only blood-sucking subfamily in reduviety, are the main vectors of chagas disease. In China, however, the diversity of this group has not yet been fully explored, with only two species having been identified so far. Two new species, triatomapictajiao and chi-SPNOV, and tiatratajiao and chi-SPNOV, were described here, along with a re-decryption of ti, cynicacyiao, 1965. Photos of the insect genitals, a distribution map, and a key to Chinese triatomani were also included. Genetic analysis confirmed the validity of the newly discovered species. This study provides valuable information about the diversity of triatomani in China, and can help identify the species present in the country.
