The main differences are the following: the abdomen of M. leechi is black and the apex of the aedeagus is sharp, whereas the abdomen of M. bivittata sp. nov. is pale yellow and the apex of the aedeagus is blunt. The space between the punctures on the elytra of M. maana is equal to the diameter of the punctures, whereas in M. bivittata sp. nov., it is about twice the diameter of the punctures. The mid- and hind-legs of M. liui are dark brown, whereas the legs of M. bivittata sp. nov. are yellowish brown. Figures 21 - 27. Monolepta bivittata sp. nov.

020F9BA2730C5CAFBA94CC408385DE09.taxon	diagnosis	Diagnosis. This species resembles M. leechi, M. liui, and M. lunata, but the length of the antennae reaches half of the body in M. leechi and M. liui, whereas in this species the length of the antennae reaches the apex of elytra. M. lunata has a rounded spot on the elytra, but in the new species there is a transverse band. This species has a transverse stripe on each elytron and its antennae reach the apex of the elytra, which can easily distinguish it from other species of Monolepta with transverse stripes.
