In having an iris of uniform coloration, L. tengchongensis sp. nov. differs from L. alpinus, L. bidoupensis, L. eos, L. firthi, L. fuliginosus, L. isos, L. khasiorum, L. melanoleucus, L. minimus, L. pluvialis, L. pyrrhop, L. tamdil, L. ventripunctatus and L. zhangyapingi, all of which have a distinctly bicolored iris.
