Remarks :

Identification confirmed by Angel Valdès and Bill Rudman

Bibliographic data :

The body is oval and high, and the notal surface is covered with a series of sharp ridges that form a reticulate pattern. The ridges, which are irregular and serrated, delimit pits of various shapes from square to pentagonal and triangular.
    The orange-yellow perfoliate rhinophores have 18 lamellae
    Ventrally, the mantle margin is approximately as wide as the foot, with several oval spots arranged in two rows around the mantle margin. The spots of the inner row are larger and fewer than those of the outer row.
    Reticulidia suzanneae is named in recognition of Suzanne Forman, Phuket , Thailand , who was the first to bring this species to our attention and was instrumental in collecting the holotype.
    Reticulidia suzanneae is clearly distinguishable from other members of the genus. The external coloration resembles that of R. fungia by having orange pigment with black spots, but R. suzanneae lacks the bluish background pigment present in the latter. Also, the black spots of R. suzanneae are always rounded, whereas in R. fungia they are irregular in shape.

The peripherical black spots are surrounded by a grey/bluish band.

A little like Reticulidia fungia...
