    It is a male Deudorix epijarbas.

    The three known species of Deudorix in Singapore may be IDed thus.
    DEUDORIX.png

    Deudorix epijarbas.
    Ground colour typically brown.
    FW postdiscal with margins mostly straight & regular.
    FW /HW submarginal bands obscure or obsolete.
    HW postdiscal typically intact & rarely broken through.
    Males & a female.

    Deudorix elioti.
    Ground colour typically grey.
    Postdiscal band with margins usually scalloped & the band more macular (spots-like).
    FW/HW submarginal bands distinct, as dark as the postdiscal.
    HW always with the postdiscal band broken through at some point.
    Orange ring is edged out in black.
    2 Males & 2 females.

    Deudorix staudingeri
    Larger species with sharper FWs & straighter outer margin.
    Similar to epijarbas but white striae weak or obscure.
    The dark striae are more prominent.
    Two males. Both from the Central Water Catchment Area.

    Could this be a Deudorix staudingeri? Shot in 2006 at TBHP.

    The HW orange spot is not surrounded in black.

    Yes. This is a male Deudorix staudingeri.

    The dark striae are prominent & the white striae somewhat faded.
    The orange ring is more rounded, & not outlined in black.


    In contrast, in D. epijarbas, the white striae are strong, the dark striae weak, the orange ring is more rectangular. It may or may not be edged darker.
    Three males of D. epijarbas for comparison.

    This observation from USR Oct 2006 is also D. staudingeri.

    Dear Doctor Seow,

    I have shot a Deudorix from USR as well, would this be a D. staudingeri or D. epijarbas? The specimen is a bit faded, and harder to ID

    The white atriae in D. epijarbas is typically very strong.
    If both white & dark striae orf the FW band are equally faded as here it is D. epijarbas.

    In contrast in D. staudingeri, the FW band's white striae fades off or become sullied, the dark striae are prominent.

    D. staudingeri with partial upperside.
    Note smaller red area on the FW.
