First record from Vietnam . Considering the first record of Ypthima motschulskyi from Vietnam we demonstrate here the images of the male from Vietnam . The male genitalia are similar to genitalia of this species illustrated in literature (e.g., Elwes & Edwards, 1893; Shrôzu & Shima, 1979 and Bascombe et al. , 1999) ( Figure 15 ). These illustrations confirm the identity of this new addition to the butterfly fauna of Vietnam .
