    Default Arctiine or Zygaenid or Stathmopodinae?

    I photographed this skittish little red moth in Semenyih, Selangor, Malaysia. Approx 1 cm in size.



    According to the ID on this Flickr image, it's Oecophoridae, Stathmopodinae - maybe Atkinsonia sp.

    http://www.flickr.com/photos/53952143@N04/4992899945/

    My entomologist friend on Facebook, Doug Yaneda, however, disagrees with the ID.

    His observations: There are a few very important differences: (1) the antennae are dramatically different in both structure and coloration (2) the resting posture of true stathmopodines is *stereotypical*, with the wings folded and the legs raised (3) the black fringe on the wings of Atkinsonia is an actual fringe, not just a black-scaled portion of the wing itself (4) the scales, especially on the thorax, of true Atkinsonia are *glossy*.

    Your thoughts on this?

    Thanks!

    I agree with your friend, though I do not know what it is. These pages illustrate his points:

    I do not see the big, curved palps in your critter either, but could possibly be the angle?

    Somehow it reminds me of a sesiid, but I do not think it is. Looking forward to the solution

    I don't think it is Oecophoridae for the way the forewings are unable to round the broad thorax to fully cover the abdomen as in Oecophoridae.
    That plus the smooth antennae.
    Here is another example of an Oecophorid, Snellenia.
    The base of the forewings are shaped to go over the lower part of the thorax.

    No match for Zygaenid from Moths of Borneo.

    No match from Arctiinae or Phaudidae.
    Phaudidae have unfringed wings..

    The brroad thorax & banded abdomen look like it should be Sesiidae although there is no direct match found.

    PS. A check shows some Oecophorids were transferred from Sesiidae. They are very similar.
    This looks likely to be a species of Snellenia , the white banded abdomen is very similar.
    Unfortunately the examples shown are from Australia.

    The Thai website clearly shows the typical posture with the large spiny hind legs raised.
    This plus the white banded abdomen & fringed wings indicates it has to be Stathmmopodinae after all.

    A crosscheck with NHM shows only a few species of Snellenia.
    Eliminating the Australian ones (which appear to be endemic) brings up 4 species. 1 spp S. latipes- Brazilian.

    S. coccinea TL Himalaya.
    S. tarsella TL Himalaya.
    S. ignispergens. TL japan.

    Default Wrong ID.

    Oops! I just realised this is neither Atkinsonia nor Snellenia.

    The curved palpi should be visible even at the angle shown.
    http://www.flickr.com/photos/itchydo...n/photostream/

    The curved palpi of Snellenia are enormous ( I thought they were legs earlier).
    http://www.brisbaneinsects.com/brisb...dMimicMoth.htm

    It looks like it is back to being a kind of Sesiid.

    TL Seow
    PS. Other examples of Oecophorids showing the palpi are easily seen.

    PS 2. More Oecophorids showing 'snout' & long fringes on FW.

    Thanks for your input, Dr. Seow, and Peter.

    There's a discussion going on in the Entomology Group in FB here. : https://www.facebook.com/photo.php?f...count=1&ref=nf

    So expert opinion is now Schreckensteiniidae.. Kurt, think that if you ever see this again, you should take (a) voucher(s).
