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.
