Facelinidae sp. 02 is an undescribed species of the family Facelinidae, it is characterized by two longitudinal orange spots between the rhinophores. The cerata are subapically pinkish, diffusing into bluish apices. There are some diffuse whitish blotches on the cerata. The brownish-tan digestive glands are confusing, they seem very thin and winding in some cerata and in others large and straight. The rhinophores are basally translucent, the outer half is whitish-pink. This specimen has a deformed or missing right rhinophore, the left rhinophore is translucent with whitish tips. The long oral tentacles are also translucent with whitish-pink tips. This species has a very long 'tail', Martin Burman wrote on this picture: "Size: 9 - 10 mm excluding the long tail".
Most probably are these specimens juveniles of Facelinidae sp. 05, which differs by a broad yellowish-orange middorsal line, and by translucent brownish cerata with whitish tips, and thick, straight, brownish digestive glands.
This species is as Pruvotfolia sp. 4 in Gosliner et al. (2015) page 379,
it was posted on 9 June 2011at these websites as Facelinidae sp. B  Family: Bergh, 1889, and changed on 20 July 2011 into
Facelinidae sp. 02  Family: Bergh, 1889.
For some genera, such as Trinchesia was the alphabet almost through. I had to change the distinguishing alphabetic character into a number. I had chosen 2-digit numbers, even though '01' looks a little bit stupid, and now is only the genus italic written.
