    In Singapore Arhopala pseudomuta can become confused with Arhopala alitaeus.

    Both belong to a group with extra FW costal spots; FW postdiscal band irregular with spot 4 dislocated & shifted out.

    Arhopala pseudomuta pseudomuta.
    HW postdiscal spot 6 trapezoid or more quadrate; HW submarginal spots form a continuous low wavy band; Markings less contrasted.

    Arhopala alitaeus pardenas.
    HW postdiscal spot 6 large with rounded margins ,often ovoid; HW submarginal spots mostly discrete & separate ;markings strongly contrasted; often purple-washed.

    Intermediate.
    HW spot 6 have less rounded margins than in alitaeus ; HW submarginal spots less discrete; markings also less contrasted than in alitaeus.
    Thisc probably have a hybrid element.
    It has more the characters of A. alitaeus & probably should be treated as such.
