    I still find that the most reliable character in damona is that the individual striae which make up the post-discal band are much straighter than the scalloped ones in dieneces
    I didn't notice this. I'll be going back to get more shots and look out for that.

    I think in R. damona, compared to R. dieneces, the post discal band appears to be 'jabbing' into the blue tornal spot. In examples of R. dieneces the is often more space between the band and the spot.

    Having compare numerous examples of what was thought to be dieneces or suffusa in the past with Jonanthan's current shots of proven R. damona male I find there is way too many variations in each species.

    The only consistencies in R. damona male appear to be .
    1. Deeper ochreous orange brown colour .
    2. FW postdiscal curved in at the top, mostly roughly parallel to termen ,& slightly nearer termen than cellend.

    R. dieneces male.
    1. Mostly lighter brown,to ochreous brown.
    2. FW band mostly straight or lightly curved , not parallel to termen & slightly nearer cellend than the termen.


    R. suffusa male ; light ochreous to deep chrome yellow.
    FW band mostly parallel to termen ,roughly midway between termen & cellend, strongly bent to the costa.

    This is why i suspected that Jonathan's shot #2 in the first post is should actually be dieneces

    What exactly does Fleming mean by "upper end"? I take it to be "curved from below the same vein as the cell streak"... because that's what it looks like

    Accidentally deleted a previous post so I'm re-posting the shots here along with 2 shots taken today. I've noticed the ground colour is quite variable too. The more worn specimens were much paler, resembling R. dieneces closely. Some pristine ones were paler too. I'll post them soon.

    The statement just means the upper end of the FW band is set further in on the costa due to a curve in the upper part of the band.

    Jonanthan's shot 2 is R. damona.

    The upperside shot shows the FW patch with a strong right-angled notch on its lower margin more characteristic of R. danona .
    See Fleming L357.

    More often in R. dieneces the HW postdiscal band is fairly regular.

    The irregularity of the HW seem only useful in R. tara which is often confused with suffusa up north.

    TL Seow: Cheers.

    PS. Whether the FW band is nearer termen or cellend is also irrelevant , as Jonathan 's latest two shots show both possibilities.

    PS2. it is necessary to see how the female damona looks. In the book it looks very similar to suffusa but more ochreous than yellow.
    The postdiscal band in space 1b is typically a low curve or convex & the speckled patch often large (both remarked upon by Jonathan & Aaron) but exceptions occur.
    eg C&P4 shows a female dieneces with a large speckled patch (P50/35) and a female damona with a small speckled patch although the band is a low curve (P51/2).

    Thanks for all the clarifications Dr Seow. Seems like it can be quite variable even on such a small island like Singapore where there are few microhabitats
