Galil B.S. 2019. Re-description and new records of a poorly known leucosiid crab, Merocryptus boletisculpta Zarenkov, 1994 (Crustacea, Decapoda, Brachyura). Western Indian Ocean Journal of Marine Science 18(2): 93-97. DOI:10.4314/wiojms.v18i2.11
Abstract [+] [-]Sixty-nine specimens of the rare leucosiid crab Merocryptus boletisculpta are reported from Walters Shoal, an isolated seamount in the southwestern Indian Ocean. The species has previously only been known from the type series collected during the R/V Vityaz 1988-1989 expedition. The species is re-described, illustrated, and colour photographs are provided.

Houart R., Zuccon D. & Puillandre N. 2019. Description of new genera and new species of Ergalataxinae (Gastropoda: Muricidae). Novapex 20(HS 12): 1-52
Abstract [+] [-]The recent genetic analysis of the muricid subfamily Ergalataxinae has led to a better understanding of this subfamily, but some species were left without appropriate generic assignments and the classification of others required revision. This knowledge gap is partially filled herein, with new combinations and the description of three new genera. The examination of new material, along with a careful re-examination of and comparison to existing material, resulted also in the identification of nine new species. These new genera and new species are described herein, lectotypes are designated and new combinations are given. The geographical range of all the new species is provided on maps. All new species are compared with related or similar species. The radula of Morula palmeri Powell, 1967 is illustrated for the first time.

Mah C.L. 2018. New genera, species and occurrence records of Goniasteridae (Asteroidea; Echinodermata) from the Indian Ocean. Zootaxa 4539(1): 1. DOI:10.11646/zootaxa.4539.1.1
Abstract [+] [-]Modern goniasterids are the most numerous of living asteroids in terms of described genera and species and they have important ecological roles from shallow to deep-water marine habitats. Recent MNHN expeditions and historical collections in the USNM have resulted in the discovery of 18 new species, three new genera and multiple new occurrence records from the western Indian Ocean region including Madagascar, Glorioso and Mayotte islands, Walters Shoal, South Africa, and Somalia. This report provides the first significant contribution to knowledge of deep-sea Asteroidea from the Indian Ocean since the late 20th Century. Several deep-sea species, previously known from the North Pacific are now reported from the western Indian Ocean. Gut contents from Stellaster and Ogmaster indicate deposit feeding. Feeding modes of this and other deep-sea species are discussed. Comments are made on fossil members of included taxa. A checklist of Indian Ocean Goniasteridae is also included.

Poore g.c.b. 2020. Axiid and micheleid lobsters from Indo-West Pacific deep-sea environments (Crustacea: Decapoda: Axiidea: Axiidae, Micheleidae). in CORBARI L., AHYONG S. T. & CHAN T.-Y. (eds), Deep-Sea Crustaceans from Papua New Guinea. Tropical Deep-Sea Benthos. Mémoires du Muséum national d’Histoire naturelle 31(213): 259-367
Abstract [+] [-]Collections in the Muséum nationale d’Histoire naturelle, Paris, made during expeditions with other French agencies in the Indo-West Pacific contain numerous species of the decapod suborder Axiidea. Here, species of 11 genera of Axiidae and three genera of Micheleidae from deep seas, particularly in the region of Papua New Guinea, are reviewed. Manaxius Kensley, 2003 is taken out of synonymy with Calaxius Sakai & de Saint Laurent, 1989 and the two genera are diagnosed. The four species assigned to Calaxius and 17 assigned to Manaxius are listed, some in new combinations. Comments and new diagnoses are provided for 19 described species: 18 of Axiidae: Acanthaxius formosa Kensley & Chan, 1998, Acanthaxius miyazakiensis (Yokoya, 1933), Ambiaxius alcocki (McArdle, 1900), Ambiaxius franklinae Sakai, 1994, Bouvieraxius keiensis Sakai, 1992, Calaxius acutirostris Sakai & de Saint Laurent, 1989, C. sibogae (De Man, 1925), C. manningi Kensley, Lin & Yu, 2000, Eiconaxius consobrinus De Man, 1907, E. demani Sakai, 1992, E. sibogae (De Man, 1925), Manaxius ohsumiensis Sakai, 2011, M. pitatucensis (De Man, 1925), Paraxius altus Bate, 1888, Spongiaxius brucei (Sakai, 1986), S. holthuisi Poore & Collins, 2010, S. odontorhynchus (De Man, 1905); and two of Micheleidae: Meticonaxius noumea Poore, 1997 and Tethisea indica Poore, 1994. Twenty new species of Axiidae are diagnosed and described: Acanthaxius sapulo n. sp., Ambiaxius meriman n. sp., Ambiaxius tudak n. sp., Calastacus karamapim n. sp., Eiconaxius budibudi n. sp., Eiconaxius ebisco n. sp., Eiconaxius johannesi n. sp., Manaxius inhambane n. sp., Manaxius iro n. sp., Manaxius supia n. sp., Montanaxius vadensis n. sp., Pillsburyaxius sisis n. sp., Spongiaxius carnasai n. sp., Spongiaxius kindam n. sp., Spongiaxius liklik n. sp., Spongiaxius lubangi n. sp., Spongiaxius matanalem n. sp., Spongiaxius nanhai n. sp., Spongiaxius nusai n. sp., Spongiaxius simlindon n. sp.; and one of Micheleidae: Marcusiaxius hoae n. sp. Axiopsis (Axiopsis) pitatucensis De Man, 1925 is designated type species of Manaxius Kensley, 2003, overcoming a nomenclatural problem introduced by Kensley (2003) who misidentified the material he discussed, a problem confounded by Sakai (2011). Four generic names are synonymised with Spongiaxius Sakai & de Saint Laurent, 1989: Platyaxius Sakai, 1994, Albatrossaxius Sakai, 2011, Platyaxiopsis Sakai, 2011 and Newzealandaxius Sakai, 2011. Calaxius tungi Zhong, 2000 is synonymised with C. sibogae (De Man, 1925), Eiconaxius bandaensis Sakai, 2011 is synonymised with E. sibogae (De Man, 1925) and Tethisea mindoro Poore, 1997 is synonymised with T. indica Poore, 1994. Acanthaxius clevai Ngoc-Ho, 2006 is transferred to Pillsburyaxius, now Pillsburyaxius clevai (Ngoc-Ho, 2006), new combination.
