Eleven species have been identified using a combination of morphological and molecular analysis (COI). Nine are new to science, they are described and illustrated based on their larvae, and in one case, complemented by the male imago. Two of the new species belong to the L. batakorum species group, L. mon sp. nov., L. lahu sp. nov.; three to the L. numeratus species group, L. tenasserimensis sp. nov., L. angularis sp. nov., L. tonsator sp. nov.
