    A single pic taken by Federick years ago suggest strongly that J. pura is extant in Singapore.

    This female have FW submarginal spots lunulate, spot large.
    The silvery side bars on the HW black spot is less prominent but this is a variable feature.

    Compare with a typical Singaporean female J. celeno .

    Compare to a female J. pura from Thailand.
