Marioniopsis sp. 05 is characterized by a reticulate pattern of dark blue lines forming polygons on the reddish body, which has a series of median tan patches, and by bright blue spots. The sheaths of the rhinophores are of the same colour as the body, including the dark blue lines and spots, but there is also some white pigment, at the margin are whitish spicules, the rhinophores have greenish-tan apices. The stalks of the gills are white with dark blue lines and spots, the gills are translucent tan.
Pretty similar are
Marioniopsis sp. 01 which differs by the pinkish background colour, by the pinkish rhinophores with turquoise apices, by the translucent turquoise gills,
Marioniopsis sp. 02 which differs by the reddish background colour, by the translucent rhinophores with white tips, by the translucent gills with minute dark spots, and by the diffuse white longitidinal median band,
Marioniopsis sp. 03 which differs by the diffuse dark blue blue lines, and
Marioniopsis sp. 04 which differs by the reddish background colour, by the series of median tan patches, by tan rhinophores, and by translucent tan gills.
There are many tritoniids with a similar colour pattern, even the bright blue spots and the dark blue lines forming polygons are not distinctive - or there is one species with many colour variants.
It was originally posted at these websites as Marioniopsis sp. A Genus: Odhner, 1934, which is now Marioniopsis sp. 01,
I realized on 15 October 2011 there were possibly 3 different species posted as Marioniopsis sp. A so I seperated Marioniopsis sp. 04 and Marioniopsis sp. 05.
