This is an unidentified or undescribed species of the genus Doto. I call it Doto sp. 08, to distinguish it from other undescribed species of Doto.
It is Doto sp. 12 in IPN at page 347
Let me quote the description: "This species is remarkable with its elongate brown body that closely resembles the rachis of its hydroid prey. The digitiform cerata are widely spaced and held parallel to the body. They have low whitish tubercles with a terminal yellowish tubercle."
The rhinophoral sheaths are translucent brownish with minute white spots, and lack the collar, or recurved flange, which is normally found in species of Doto. The rhinophores are brownish.
Confusing is the picture of this species in IPN, this specimen holds the cerata in a right angle, not parallel to the body!
IPN writes: "Known only from Papua New Guinea"
There are some pictures of it from Japan as Doto sp. 11 made by Jun Imamoto at Medslugs, in these specimens the cerata point all forwards, and are hold downwards covering the foot.
A picture of it from East Timor by Brian Francisco is as Doto sp. 11 at the Sea-Slug Forum, in this specimen the cerata also point all forwards, but they are hold upwards, just like the above specimen from the Philippines.
