Found at Choi Sai Woo Park, Braemar Hill, North Point, Hong Kong on December 18, 2002.  Although its shape and markings (note the single, prominent white dot  and the row of three smaller dots) are similar to  Lawana imitata, it is quite a bit smaller at nearly half the size, not to mention the color.  Could it be a difference due only to gender dimorphism?
