Pseudoceros goslineri Newman and Cannon, 1994
Type material location
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.
The diagnostic character of this species is the cream color mottled with orange, pink and purple dots concentrated medially forming an elongated blotch. Margin with purple and pink dots.
External anatomy: Flatworm with irregular and variable color patter characterized mainly by a cream background mottled with orange, and pink and purple-red dots concentrated medially forming an elongated blotch. The margin consists of purple and pink irregular spots and dots that are more concentrated on the tentacles making the tips a little darker. The ventral side is light violet. Pseudotentacles formed by simple folds of the anterior margin with few marginal eyes. Cerebral cluster made of about 30 eyespots. Presence of a broad folded pharynx.
Internal anatomy: The male reproductive system consists of unbranched vas deferens, an elongated seminal vesicle connected to a short and coiled ejaculatory duct, a round prostatic vesicle, and a small stylet housed in a deep antrum. The female system has a deep and tubular female antrum with curved cement pouches and a short vagina directed backwards and surrounded by the cement gland.
Ecology and Distribution
This species has been found in Heron Island and One Tree Island, Central Great Barrier Reef in Australia, and Madang in Papua New Guinea.
Evolution and Systematics
This species was described by Newman & Cannon (1994) and included into the group 4 distinguished by spots, dots, and mottling, according to the categorization based on the color pattern created by the same authors. P. ouini is in the same group and closely resembles P. golisneri showing also a cream background with pink spots at the margin.
