Pseudoceros jebborum Newman & Cannon, 1994

( Fig. 2 )

Material examined. AM W.45203, MI QLD 2448, sagittally sectioned.

Description. Elongated body is 23 mm long and 6 mm wide. Dorsal colour pattern is yellowish-white, with three marginal bands: inner black, white in the middle, and a yellow outer rim ( Fig. 2 A). Sucker is at middle of the body, far from female pore. Seminal vesicle elongated, slightly flattened, oriented anterio-posteriorly. Prostatic vesicle is elongated. Ejaculatory duct is directed backwards. Prostatic duct is narrow. Penis papilla, backwards, armed with a thin and long stylet, is housed in a shallow male atrium ( Fig. 2 B, C, E). The female genital complex ( Fig. 2 D, E) represents the configuration characteristic of the genus.

Remarks. The stylet in the examined specimen is thin and similar to that of P. astrorum ( Bulnes & Torres 2014) , but with a less pronounced curvature.

Distribution. Previously found in Heron Island and Coral Bay, Australia ( Newman & Cannon 1994b, 1998), Hawaii ( Gosliner et al. 1996), and Mandang, Papua New Guinea ( Newman & Cannon 1994b). First report for Lizard Island.
