Erwin's photo of the gastopterid looks a lot like a pale version of Sagaminopteron ornatum. We have found typical colored individuals at Cabilao Island on one of our Philippine trips. The presence of the distinct ridge anterior to the "flagellum" is also consistent with S. ornatum, but is not found in Siphopteron quadrispinosum.

I wondered whether that ridge was significant. However there is one, perhaps significant, difference with S. ornatum and that is the presence of a distinct median pigmented ridge down the metapodium, or posterior part of the foot. I guess we will have to wait until its anatomy is known
