It looks like Lindsay's runcinid is Ilbia (or Pseudoilbia) mariana Hoff & Carlson, 1990. Don't know what it is doing so far from home.

The species can vary quite a bit in color. I think we sent some color (colour) prints with the reprint we sent you. I can't get decent scans of the two darker variations.

Thanks again. I'm afraid I looked at your 2 colour prints of the dark colour form and didn't connect them with Lindsay's animal. Once I got your message and checked your reprint it is very clear that the Sulawesi animal is your Ilbia mariana. I'll see if I can scan your colour print.
