X. mexicanorum vs. X. varipuncta
 X. mexicanorum - Wings, color, VERY DARK - Wing surfaces, with STRONG REFLECTIONS of blue and purple - Overall wing color DARKER in comparison with X. varipuncta (1)
 X. varipuncta - Wings, color, BRONZY except apically - Wing surfaces, only with SLIGHT bluish REFLECTIONS - Overall wing color LIGHTER in comparison with X. mexicanorum (1)
