Pseudobiceros flowersi Newman & Cannon, 1997

( Fig. 7 )

Material examined. AM W.44685, MI QLD 2410, sagittally sectioned.

Description. Elongated body is 60 mm long and 25 mm wide. Dorsal colour pattern is golden yellow background with two mid-dorsal lines, one is wider, dark, another is thinner, white, formed by very small dots; three marginal bands are an inner black, olive green in the middle, and narrow white outer rim ( Fig. 7 A). Seminal vesicle is oval, heavily muscularized, ventrally inclined to distal end. Prostatic vesicle is long, narrow. Ejaculatory duct is short, descends straight to penis papilla base. Prostatic duct is small, narrow. Penis papilla is armed with a long conic stylet, inside a shallow atrium ( Fig. 7 B, C, E). Female system ( Fig. 7 D, E) has the configuration characteristic of the genus.

Remarks. The colour of this species in the original description and diagnosis ( Newman & Cannon 1997) is olive green to brown, with black-green-white marginal bands, and white narrow and black wide mid-dorsal line. The examined specimen presents a yellow background instead of olive green.

Distribution. Previously found under rubble in Lizard Island Lagoon (Lizard Island, Australia) ( Newman & Cannon 1997) and also in Luzon, Philippines (Luzon, Philippines ( Gosliner et al. 1996)).
