Christmas Photo Puzzle 2021

Trewavas; therefore trewavasae; not sure which genus however...

 

Labeotropheus trewavasae?

 

Yes! A splendid red top OB male (a 'marmalade cat'), owned by a friend of mine. The only photo in the puzzle that wasn't taken in a zoo. I wanted to include it as another species named after a woman and, in particular, because I once had the pleasure of a conversation with Ethelwynn Trewavas: she was very old and her eyesight was poor, but her mind was clear and she was interested in my observations of the behaviour of Tanganyikan goby cichlids.

 

Now who can refine the rank order posted above by @Gavialis?

*Although Linnaeus was knighted in 1753 and ennobled in 1761, I don't think he was granted any official titles.

 

Excellent! The first prize of the 2022 goes to @Gavialis. Unfortunately it's only a virtual prize, but it was really well earned!
As I said before, it's not worth debating the titles too much. Queen Victoria graciously accepted the title of Empress of India from Mr Disraeli, so she ranks with Kaiser Bill and the self-crowned Corsican. Prince Alfred eventually became Duke of Saxe-Coburg & Gotha too, although that was part of his nephew's empire. Lady Ross's title came when her husband, the explorer, Admiral James Clark Ross was knighted. Linnaeus chose the title Karl von Linné when he was ennobled, but I don't know whether that puts him at the same rank as an English baronet or a French baron - and actually I don't care
My thanks and compliments to everyone who took part; I hope this little brain-teaser provided a little mental stimulation during the holiday.

 

And thank you, @gentle lemur, for organising the challenge - it was great fun and a real joy to complete. Credit must, of course, also go to @amur leopard, @Prochilodus246 and @Tetzoo Quizzer for helping to solve the tricker images!
