Paulodora subcontorta (Schockaert, 1982) Artois & Schockaert 1998
No full textPaulodora subcontorta (Schockaert, 1982) Artois & Schockaert, 1998 (Fig. 4 C, K) Syn. 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.Published as part of Artois, Tom J. & Tessens, Bart S., 2008, Polycystididae (Rhabditophora: Rhabdocoela: Kalyptorhynchia) from the Indian Ocean, with the description of twelve new species, pp. 1-27 in Zootaxa 1849 on page 16, DOI: 10.5281/zenodo.18337

Paulodora drepanophora Artois & Tessens 2008
No full textPaulodora drepanophora Artois & Tessens, 2008 (Fig. 6 B–C) New localities. iSimangaliso Wetland Park, Eastern Shores, Mission Rocks (28°16’50.4’’S, 32°29’06.5’’E), sand and shrubby red algae from rock pool in the mid-eulittoral of a highly-exposed tidal area with sandstone terrace covered with invertebrates (barnacles, mussels, limpets, corals, tunicates), December 5, 2009; same locality (28°16’41.5"S, 32°29’10.6"E), red algae from a swirl hole close to the footpath from the parking lot, December 12, 2009. Known distribution. Kenya, Mombasa, McKenzie Point & Tiwi (Jouk & De Vocht 1989; Artois & Tessens 2008). Somalia, north of Mogadiscio, Hawadli and Warshek (Schockaert 1982). Material. Two whole mounts from South Africa (HU, nos VII.3.49–VII.3.50). All material from the original description, including the holotype. Additional remarks. Habitus and general organisation do not differ from that of other species of Paulodora Marcus, 1948, a monophyletic taxon to which it undoubtedly belongs (see Tessens et al. 2014). The umbrellashaped, sclerotic "nozzles" on each of the oviducts typical of all species of Paulodora (see Artois & Schockaert 1998) are clearly visible on live specimens as well as on whole mounts (Fig. 6 C). The prostate stylet type I of the South African specimens is 64–67 µm long (n = 2), which is only marginally longer than the known range (42–62 µm; Artois & Tessens 2008). In contrast with the specimens from the original description, the distal part of the stylet is not folded downwards. Therefore, the sickle-shape is less obvious. This folding is probably an artefact caused by the degree of squeezing of the specimen and also occurs in species with similar stylet morphology, such as Paulodora felis (Marcus, 1948) Artois & Schockaert, 1998 and P. asymmetrica Artois & Schockaert, 2001 (see Artois & Schockaert 2001).Published as part of Willems, Wim R., Reygel, Patrick, Steenkiste, Niels Van, Tessens, Bart & Artois, Tom J., 2017, Kalyptorhynchia (Platyhelminthes: Rhabdocoela) from KwaZulu-Natal (South Africa), with the description of six new species, pp. 441-466 in Zootaxa 4242 (3) on page 455, DOI: 10.11646/zootaxa.4242.3.2, http://zenodo.org/record/37690

Habitus and internal organisation almost identical to the original description, showing all diagnostic features of the taxon (Artois & Schockaert 1999), the only difference being the shorter length of the common genital atrium in comparison with that of specimens from Zanzibar. This observation could, however, be the result of the slightly-different orientation of the sections.</p> <p>The South African specimens occur in a brackish habitat with very low salinity, whereas on Zanzibar they were only found in pure marine habitats.
