Sulawesi runcinid is Ilbia mariana

Bill,
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.
UPPER PHOTO: 3.3mm; Guam, Bile, boat Channel;  27 April 1990. LOWER PHOTO: 3.2mm; Guam, Cocos Lagoon; 6 November 1971.

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.

Dear Clay,
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.
Bill Rudman.
