Chromodoris lochi from Lembeh Strait

January 15, 2007
From: Wyatt Ang

Hi Bill,

I need your expertise yet again. This bluish white species of Chromodoris looks like a combination of C. annae, C. dianae, C. willani and C. elisabethina althogether. I have difficulties distinguishing and identifying this specimen. It has yellow rhinophores and gills but lack the obvious white specks present in C.willani. It looks like C. elisabethina but lacks the continous yellow/ faint yellow margin. It also has a discontinous black median line which is not characteristic in C. annae. Its mantle skirt and foot looks like C. dianae but the the black line markings, the all yellow gills and bluish pits/specks are typically not of C. dianae. So which is it?

Locality: Lembeh Strait, 7m, Indonesia, Mollucca Sea, 13 November 2006, Coral reef with sponges, Silty, black volcanic sand. Length: 50 mm. Photographer: Wyatt Ang.

Wyatt

Dear Wyatt,

One species you don't include in your comparison is Chromodoris lochi which is quite similar in colour to C. willani but has yellowish gills and rhinophores and a narrower mantle skirt. This species seems to range from animals with a very pale whitish background colour to ones like yours with a bluish tinge to the body..

Best wishes,
Bill Rudman
