Erwin Koehler This one is from Anilao, Philippines, any idea ob the genus is welcome, it has the same color pattern as Placida cremoniana and or Favorinus tsuruganus, but is clearly none of them! HELP

Ajiex Dharma Looks like Favorinus tsuruganus.

Erwin Koehler This one has smooth black rhinophores with whitish tips, in F. tsuruganus have the black rhinophores three 'cup-shaped' or 'collar-like' swellings, this unknown beauty has black oral tentacles, in F. tsuruganus are they white.

Blogie Robillo Lovely!

Vishal Bhave There is third species with similar coloration Eubranchus mimmeticus but rhinophores doesn't have white tips. Looks like Favorinus tsuruganus.

Erwin Koehler I don't know the description of Eubranchus mimeticus, but all of the 13 pictures at http://www.umiushi-zukan.com/eng/list_pic.php?ssw=g&kind_id=631 have a white median line between the rhinophores, and most specimens have white pigment at the cerata, often white longitudinal lines or white patches basally, the rhinophores seem to be often whitish basally with a black outer 2/3.

Gary Cobb This is Facelina sp. http://www.nudibranch.com.au/pages/IMG_a0588w.htm I have found it here on the Sunshine Coast.

Erwin Koehler YES this is the same species! thanks!

Gary Cobb You're quite welcome!

Vishal Bhave Dear Erwin Koehler if you have visited http://www.nudibranch.com.au/pages/IMG_a0588w.htm (Image 3-6) the species illustrated (IMG_a0588w) has median white line running between ceratal tufts. It has color variations from pale whitish (justlike those lines to pure Orange with blue tips and Rhinophores (with white tips) we have simmilar species here and http://www.nudipixel.net/photo/00024010/location/ it shows typical radula as seen in Eubranchus (at least in specimens from Ratnagiri).

Erwin Koehler I contacted Rie Nakano, she sent a pdf-file with the Text-fig. 3 from Baba 1975 with the drawing of the 3 mm holotype, it shows a broad white median band Baba: mw: median dorsal opaque white band, and longitudinal white lines on the ceras Baba: ws : longitudinal opaque white streaks. Rie Nakano writes:" I think Eubranchus mimeticus does not belong to genus Eubranchus. In the near future, it will be changed to another genus...I think."

Gary Cobb Lets not get too far off the track. The photos I submitted in an earlier thread are not Eubranchus mimeticus. Similar yes. This species has also been verified by Richard Wilan where the preserved specimen lays.

Vishal Bhave Thanks for the information :D

Ana Lama Y este????

David Serrano Se te ha quemado un poco

Victor Sanchez Sabia yo que enseñarías una placida cremoniana!! Nico la vio y ese dia yo no estaba jajaja

Ana Lama Es para picar a Manuel , ja, ja

Manuel Martínez Chacón Una bonita Placida cremoniana... por desgracia yo aún no me he topado con ella...

Manuel Martínez Chacón Por cierto, este tampoco es un nudibranquio, sino un opistobranquio de la familia de los sacoglossos (como el Thuridilla hopei).
