Polycystis subcontorta Schockaert, 1982 Known distribution . North of Mogadiscio (Hawadli) ( Schockaert 1982 ). New localities in the Indian Ocean . Bird Island ( Seychelles ): south-east part of the island, coarse sand from a little pool on the reef front ( 24/12/1992 ). Desroches Island ( Seychelles ): a little bit of sand and Halimedia from rocks under the reef ( 24 m ) ( 07/01/1993 ). Zanzibar Island ( Tanzania ): Ulva -like algae and short encrusting algae from rocks and a rocky stair behind the Institute of Marine Sciences ( 10/08/1995 ). Material . The material of the original description, including the holotype (now in SMNH ). Three animals studied alive, one from each new locality, all of them mounted. Remarks . The record in Kenya by Jouk & De Vocht (1989) refers to another species: P. h a m i f e r n. sp. (see earlier). The prostate stylets type I of the newly-found specimens are 100–145 µm long (= 124, n = 3). This range clearly fits the measurement on the holotype , which has a 126 µm-long stylet ( Schockaert 1982 ). In one of the newly-found specimens, the “vesicles” communicating with the oviducts (see Schockaert 1982 ) are filled with sperm, thus they function as seminal receptacles.
