I encountered Siphopteron sp. 1 in which the tip's orange color is very light.
5m depth, 3mm long. November 1999 at Kerama Is. I try to find lighter than this.

Thanks very much for the photo. It certainly is much lighter than the earlier photos of Siphopteron sp. 1. Unfortunately I don't think we are going to be able to tell whether this means that Siphopteron sp. 1 and Siphopteron sp. 2 are colour forms of each other until we can compare the internal anatomy of them both. Both seem to have a slender 'tail' off the rear of the visceral hump and another slender projection from the posterior tip of the foot so there are not any other easily visible external characters we can look for.
Another photo of Siphopteron sp. 1.
