    Theretra clotho & tibetiana.

    It is not possible to differentiate between the two as they are practically identical.

    The distribution of the two are slightly different & as far as I can see T. tibetiana has not been recorded in India.

    T. clotho is found in Thailand but not T. tibetiana.

    Theretra lucasii & latreillii.

    T. lucasii was formerly treated as a subspecies of T. latreillii.

    T. lucasii is oriental while T. latreillii is Australasian.

    T. lucasii. Wings triangular with straight margins, like a jet fighter.
    FW with extra submarginal lines beyond the dotted postmedial visible.

    FW margin more convex & submarginal lines not visible.

    Theretra boisduvalii & T. sumatrensis.


    Two species were formerly confused as one.
    Both have the postmedial running from the apex marked out by dots on the veins.

    T. boisduvalii.
    Upperside greenish brown.

    I see from the Sphingidae series that T. tibetiana have been reported from Bhutan & Manipur.

    They are practically identical.
    Perhaps the pale line inner to the postmedial running from the apex is better defined in T. clotho.

    2 & 4 where this line is very weak might be possible T. tibetiana.
