8629C2365D08FFFB4CBAF869FBD1FD5D.taxon	discussion	Remarks. Lingula anatina is very rare in the studied material, being found only at one locality. However, this species was already reported from north-western Australia (Emig 1982; Bryce & Sampey 2017). Its shell is elongate oval with subparallel lateral margins and a nearly straight anterior margin. The shell surface is smooth with distinct growth lines, of bright green to brownish colour. Lingula anatina is very widely distributed in the tropical and subtropical zones of the Indian and Western Pacific Oceans (Emig 1982, 1984, 1997).	en	Bitner, Maria Aleksandra (2025): Recent brachiopods from north-western Australia.

8629C2365D0BFFFB4CBAFA54FB40F849.taxon	discussion	Remarks. Although the material is very limited and poorly preserved, without possibility to investigate internal structure, we can assign this specimen to Thecidellina blochmanni as it is the only thecideide species reported from Christmas Island which is its type locality. In the opinion of Simon et al. (2018) the specimens from the Red Sea described by Logan & Bitner (2013) as T. blochmanni represent another species, thus Christmas Island seems to be the only locality of this species (Marsh & Fromont 2000; Logan et al. 2015; Simon et al. 2018).	en	Bitner, Maria Aleksandra (2025): Recent brachiopods from north-western Australia.

This is the first record of this species from NW Australia, having previously been recorded off Indonesia, Borneo and Kei Island (Jackson & Stiasny 1937; Zezina 1981; Logan 2007). It is very rare in the material examined, represented by only one specimen. Dysedrosia borneoensis is a very large species, characterized by an elongate outline and broad folding. Its surface is smooth ornamented only by indistinct, numerous growth lines. The beak is erect with a large, labiate epithyrid foramen.	en	Bitner, Maria Aleksandra (2025): Recent brachiopods from north-western Australia.

8629C2365D0DFFFC4CBAF9ABFB7BFDAA.taxon	discussion	Remarks. Dallithyris murrayi has been so far known from the Maldive Islands and the Saya de Malha Bank (Muir-Wood 1959; Zezina 2010). The present finding is its first record from the eastern Indian Ocean. In the studied material D. murrayi is a rare species, being represented by three specimens. The shell is subpentagonal in outline, ventri-biconvex. Its surface is smooth with indistinct growth lines. The beak is suberect to erect with a rounded, labiate foramen of epithyrid type. Symphytium is very small. The laterial commissure is dorsally convex, while anterior commissure widely uniplicate. The pedicle is very short, distally splitting into numerous strands. Dallithyris murrayi can be easily distinguished from D. fulva (Blochmann, 1906), the species from southeastern Australia and Tasmania; in comparison to the former species, the shell of D. fulva is oval elongate in outline with rectimarginate lateral and anterior commissures (Blochmann 1906, 1908, 1914; Cooper 1983).	en	Bitner, Maria Aleksandra (2025): Recent brachiopods from north-western Australia.

8629C2365D0CFFFF4CBAFC39FCD4FEAE.taxon	discussion	Remarks. Terebratulina callinome is the second most common species in the studied material. This species is large as for the genus. Its shell is elongate oval in outline with the surface covered with numerous ribs flattening anteriorly. The inner socket ridges are narrow. The loop forms a ring with a transverse band medially folded. Terebratulina callinome is recorded for the first time from off Australia and this is its southernmost occurrence, being previously known from the NW Pacific from Japan to the Philippines, Indonesia and Borneo (Jackson & Stiasny 1937; Cooper 1973 b; Zezina 1981, 2010; Logan 2007).	en	Bitner, Maria Aleksandra (2025): Recent brachiopods from north-western Australia.

8629C2365D0EFFFE4CBAFAC5FAF3F84B.taxon	discussion	Remarks. Frenulina sangiunolenta is very rare in the material examined but has been already reported from NW Australia (Richardson 1973 b; Bryce & Sampey 2017). Its smooth surface with red dashes makes this species easily distinguishable. The shell is of small size, biconvex, slightly unisulcate with a large, circular foramen. It is one of the most widespread species. It is recorded in the Western Indian Ocean (Bitner & Logan 2016), while in the Western Pacific it is known from Japan, Australia and New Caledonia to Fiji, Tonga, French Polynesia and Hawaii (Thomson 1918; Hatai 1940; Richardson 1973 a, 1973 b; Emig 1987; Laurin 1997; Bitner 2006 a, 2006 b, 2008, 2009, 2010, 2014, 2015; Simon & Hoffmann 2013; Álvarez 2016; Simon et al. 2016, 2018; Bitner & Romanin 2018).	en	Bitner, Maria Aleksandra (2025): Recent brachiopods from north-western Australia.

8629C2365D00FFF04CBAFF58FDA4FC42.taxon	discussion	Remarks. Jolonica hedleyi is very rare in the material under study. The shell is elongate oval, ventri-biconvex, with a smooth surface and broadly sulcate anterior commissure. The ventral valve is with a large, circular, permesothyrid foramen. The pedicle collar is closely applied to the floor (sessile). The teeth are short but wide, supported by strong dental plates. The investigated specimens show a more elongate outline than the holotype (see Cooper 1957; MacKinnon & Hiller 2010). This is the first record of this species from off Australia, previously known from China, the Philippines and the Malay Archipelago (Dall 1920; Jackson & Stiasny 1937; Zezina 1981, 2010; Logan 2007; MacKinnon & Hiller 2010). Recently Robinson et al. (2023) mentioned, however without description and / or illustrations, the presence of J. hedleyi from New Zealand, thus the geographic range of this species would be strongly extended.	en	Bitner, Maria Aleksandra (2025): Recent brachiopods from north-western Australia.

8629C2365D00FFF34CBAFA00FE8CFC16.taxon	discussion	Remarks. With 128 specimens Jaffaia jaffaensis is a dominant species in the material under study. The shell is subcircular in outline, biconvex with valves nearly equally convex, and gently unisulcate. Its surface is smooth with numerous growth lines. The beak is suberect, beak ridges present. The foramen is small, of mesothyrid to permesothyrid type, deltidial plates conjunct. The long loop is attached to the median septum. Jaffaia jaffaensis is an Australian endemic species, well known from southern Australian coast from Perth to Sydney (Richardsan 1994, fig. 4; Logan 2007; Verhoeff 2023 a). From NW Australia J. jaffaensis is recorded for the first time.	en	Bitner, Maria Aleksandra (2025): Recent brachiopods from north-western Australia.
