Differential diagnosis. Mimastra maai is close to M. malvi . Both species have very similar coloration (head and pronotum yellow, elytra dark metallic blue with thin yellow margins) but differ in the shape of the pronotum (1.45 times as broad as long in M. maai , 1.95 times as broad as long in M. malvi ) and the structure of the aedeagus ( Figs. 3–4 ). Spermatheca as in Fig. 7 .

Distribution. China: Fujian ( GRESSITT & KIMOTO 1963), Vietnam (present paper).

Comments. Originally described from three specimens: holotype (male) and one paratype (female) deposited in BPBM and one paratype (female) deposited in the California Academy of Science (San Francisco, USA).
