Remarks :

There is in our region a group of nudibranchs that I will call Phyllidiella meandrina/rosans/zeylanica difficult to identify, for two reasons: on the one hand the existence of many intermediate forms and on the other hand the very marked differences of opinion between specialists about these species ... I finally decided to make a classification (very questionable) of these specimens
            - Group Phyllidiella rosans : There are 6-9 rounded, longitudinal pink ridges which are relatively smooth
            - Group Phyllidiella cf. rosans : Up to nine rounded, longitudinal pink ridges which are relatively smooth with with surnumerous pink tubercules
            - Group Phyllidiella meandrina : In the central part of the mantle there a characteristic pattern of pink to grey-blue rings
            - Group Phyllidiella cf. meandrina : The disposition of the tubercles looks like P. meandrina but there are transverse black area beetween the tubercles all over the notum
            - Group Phyllidiella zeylanica : In adult, up to nine longitudinal pink ridges (broken or interrupted) may occur and medially, presence of a more or less developed network of black band around the tubercles

Not a very clear one, but… the outer complete circles of tubercles, and inside looks like two oval groups, not the angular clusters of P. pustulosa … The foot (a) is a uniform dark grey with a thickened edge…
