Abstract
Zographetus rienki sp. nov. is described from southern China based upon two males and one female which are associated by COI barcode. The male of this new species is distinguishable by the following combination of external characters: on the ventral side of the forewing, there is a black hair tuft at basal dorsum, cubitus and basal Cu2 are swollen, and the origin of vein Cu2 is much nearer to wing base than to vein Cu1; both sides of the hindwing are unmarked. The structure of male genitalia also differs from those of all the known congeneric species. Adults and genitalia of the type specimens are illustrated. A key to species of the genus is provided based upon previous works.
