Mexichromis mariei? from Japan

From: Nishina Masayoshi

Dear Bill,
From the discussion, I knew that it's bit difficult to tell M. mariei and M. festiva from it exterior features.

This animal dose not look like an animal that I posted before which you identified as
Mexichromis mariei. But I feel this animal is M. mariei, because the reddish-purple spots are not flat or on a slightly rounded bump, they look more like slightly pointed tubercles to me.

Data: Hachijo Island, Japan. 7 April 2002
Length: 20mm., Depth: 10m

Dear Nishina,
I agree that this seems to fall into the range of variation we are finding in this 'species'. Sone day we will sort them out. There is one interesting feature you can see in the bottom left photo. At the back of the mantle, on the right side you can see a white swelling benath the orange border. In Mexichromis large mantle glands are concentrated at the posterior end of the mantle where they form a group of often prominent swellings on the underside of the mantle edge.
Best wishes,
Bill Rudman.
