Tetraserica konchurangensis sp. n. is very similar to T. shangsiensis Liu et al., 2014, T. namnaoensis sp. n., and T. smetsi sp. n. in shape of the aedeagus. Tetraserica konchurangensis sp. n. differs from all three by the left paramere lacking a tiny tooth before the apex. Etymology. The new species is named with reference to its occurrence in the Kon Chu Rang Nature Reserve (adjective in the nominative singular).
