Cuthona kanga? from Tanzania

Hi Bill,
I see that you are calling this Cuthona sp 1 on the Forum. Like Erwin I also identified it as Cuthona kanga from Debelius, but on looking at the original description I think you may be right that that is a different species. At least my pictures extend the range of this entity to East Africa. It was on a hydroid which looked like Lytocarpus or Aglaophenia, probably the same one as Erwin's.

Pemba Island, Tanzania - February 1999

Dear Bernard,
I'm glad you sent these photos as it made me relook at this animal and my notes on it. I think it is a dark form of Cuthona yamasui Hamatani 1993. I think it has an orange and a blue-black colour form, much like Phestilla melanobrachia, though whether the colour change is related to food colour as in Phestilla I wouldn't know.


Interestingly, Hamatani and Erwin Koehler report its food as Aglaophenia and you think yours were on a similar looking hydroid.

Best wishes,
Bill Rudman
