Following Shouichi Kato's message regarding Doto pita, here is a photo of this species from Abaco, Bahamas. The 6mm specimen was collected by Rodger Bunnell from floating Sargassum between Fish Cays and Treasure Cay, Abaco on June 29, 1995. Although occasionally found on floating Sargassum, D. pita is more commonly found close to shore in the Abaco area, on a species of Sargassum [S. platycarpum?] that is attached to rocks in about 1m.
To add to your list of references, Ortea et al. (1999) reported that D. pita was amphiatlantic, having recorded the species from Cuba and from the Canary Islands.

When I first saw your photo in your book it didn't seem to fit Marcus' description that well but on reflection, and on rereading the later descriptions, including Edmunds & Just (1985) from Barbados, I think you are probably right. It is unfortunate that many Marcus descriptions, although often detailed anatomically, give little information on the external animal. I think it is unlikely that the Japanese animal is the same species.
