Pseudoceros scintillatus Newman and Cannon, 1994
The diagnostic character for this species is the black background with large and irregular yellow-green maculae and an orange marginal band.
External anatomy: Small body with a black background. Large irregular yellow-green maculae bordered by white, distributed over the dorsal surface and extending to the margin. Presence of a distinct wide orange marginal band. Pseudotentacles formed by simple folds of the anterior margin with some psudotentacular eyes, a round cluster of cerebral eyes and a small ruffled pharynx.
Internal anatomy: The male system consists of unbranched vas deferens, a large and rounded seminal vesicle, and a spherical prostatic vesicle. The penis stylet is relatively small and is housed in a shallow antrum. The female system is located close to the male complex and has a superficial antrum and a short and small vagina directed backwards surrounded by a small amount of cement glands.
This species has been reported for Heron Islands in the Great Barrier Reef, Australia.
This is a rare species found under boulders at the reef crest.
The holotype is a whole mount of an entire specimen and the paratype is a set of serial histological sections deposited at the Queensland Museum in Brisbane, Australia.
This species was included into the group 5, characterized by a maculae pattern, according to the categorization based on the color and color pattern made by Newman & Cannon (1994). P. lindae and P. glaucus are also in the same group with a similar pattern, but they differ in the color, being burgundy with yellow maculae and grey with black maculae respectively. P. mossambicus also resembles P. scintillatus but P. mossambicus has spots instead of macula and has been placed within group 4 distinguished by spots, dots and mottling.
