Mexichromis festiva
(Angas, 1864)
Sascha Hofmann Same question as Deb Aston, is this Chromodoris Daphne or something else? There are yellow dots around the mantle but no red border. Found at Cook Island about a month ago.
Gary Cobb This looks like Mexichromis festiva (Angas, 1864) to be sure if you have another shot showing its tail there would be a purple edge on it.
Sascha Hofmann No other shots :( But the gills are more purple than red (like on deb's photo)
Phil Trezise This nudi was seen by Bronwyn Trezise and I at the Southport Seaway, 4.5 m depth, 20 mm long. Is it Mexichromis festiva? As this species is listed as rare in Gary's book I would be interested in a positive ID as we saw at least 3 different individuals.
Gary Cobb This little beauty is Mexichromis mariei
Gary CobbMexichromis festiva, M. mariei and M. multituberculata can be quite variable. The simplest way to differentiate them is generally by the height of the pustules. M festiva is low, M. mariei is moderately high and M. multituberculata is extremely high. These observations are not as accurate as DNA analysis.
Bronwyn Trezise Thanks Gary. :)
Phil Trezise Thanks Gary Cobb
Patrik Good Good work! Isn't it a breathtaking beauty? Mexichromis mariei at the Seaway was only IDed as such by Gary a short while ago. I have quite reliably found this species there in the past few weeks. I also uploaded the picture of a small, cute little juvenile on this forum. So, hopefully they will stay around for a little bit. The Gold Coast Nudibranch facebook page is listing Mexichromis festiva (hopefully they will correct or have corrected the typo in mariei) in their database. My records show that what we had IDed as M. festiva was actually M. mariei all along. Although my stats are still very yound I reckon that M. mariei is a returner - a branch that might come and go every year. First find 28/10/2011. M. festiva could be a rare find I guess. I haven't documented one at the Seaway as of yet.
Patrik GoodMexichromis festiva. Gold Coast Seaway, 8/6/2012, depth 2 metres, size about 40mm. I think I have never shared this photo with this group. I like the colours and think the name is just so appropriate. Occasionally, we found this critter under ledges, well hidden in the dark. This one was crawling out in the open during an early morning full moon day dive when the sun had just said hello.
Patrik Good It should be 6/8/2012. August 6.
Gary Cobb Patrik I think this Mexichromis mariei
(Crosse, 1872)
The margin is quite wide and the pustules are many and large.
Patrik Good Oh, even better. Then it is a new species for the Gold Coast Seaway. Makes me smile because I had only guessed after the dive but the actual ID was from someone else. Thanks, Gary Cobb.
Gary Cobb You're quite welcome. This is a beautiful critter.
Patrik Good To be honest, I was more excited about finding this nudi than about the Noalda sp. that I found in the same dive.
