Four new species and two new genera of Metapseudidae <br />(Crustacea: Tanaidacea: Apseudomorpha) from Australian coral reefs

Abstract

This paper presents the descriptions of two new genera and four new metapseudid species collected from the coral reefs of Ningaloo and Heron Island in northwestern and eastern Australia, respectively. Two of the species, Curtipleon chadi n. sp., and Creefs heronum n. gen. n. sp. are members of the subfamily Synapseudinae, one, Msangia mussida n. sp. is a member of the subfamily Msangiinae and one Bamberus jinigudirus n. gen. n. sp. is a member of the subfamily Chondropodinae. With the exception of M. mussida that was found on live coral, all of the species were associated with dead corals.

Muvi schmallenbergi gen. nov., sp. nov. (Crustacea, Tanaidacea) from the southeast Australian coast, with comments on the distribution and habitat preferences of Chondropodinae

“…For example, Bamber (2005) described 24 new species from Esperance Bay, Guţu (2006a) reported 13 new species from tropical zones of Australia, Edgar (2008) reported 12 new species of the family Tanaididae in Tasmanian waters, and Błażewicz-Paszkowycz & Bamber (2012) described 42 new species from the Bass Strait. As a result, the number of the tanaidaceans known to occur along the Australian coast increased from 22 to 209 (as summarized by Bamber, 2008 ; Edgar, 2008 ; Błażewicz-Paszkowycz & Bamber, 2009 ; Błażewicz-Paszkowycz & Zemko, 2009 ; Stępień & Błażewicz-Paszkowycz, 2009a , 2009b ; Błażewicz-Paszkowycz & Bamber, 2012 ; Edgar, 2012 ; Jóźwiak & Jakiel, 2012 ; Bamber, 2013 ; Bamber & Błażewicz-Paszkowycz, 2013 ; Stępień & Błażewicz-Paszkowycz, 2013 ; Gellert & Błażewicz, 2018 ). This demonstrates the high diversity of these small and poorly recognized peracarids along the Australian coast ( Bamber & Błażewicz-Paszkowycz, 2013 ), with a high level of endemism ( Błażewicz-Paszkowycz & Bamber, 2012 ; Błażewicz-Paszkowycz, Bamber & Anderson, 2012 ).…”

“…Trichapseudes tridens Barnard, 192031-155 -Barnard, 1920 Vestigiramus antillensis Guţu, 2009 1-2 Dead corals and seagrass beds Guţu, 2009 Vestigiramus codreanui (Guţu, 1996) 29 Limestone concretions and algae Guţu, 1996 thomassini Guţu, 1989 found at 250 m, Calozodion pabisi Jakiel & Jóźwiak, 2015 found at 386 m, and Julmarichardia alinati Guţu, 1989 recovered in a wide depth range from 6 to 450 m (Table 1). Chondropodinae and other members of the family Metapseudidae are usually associated with coral reefs or hydroid colonies (Sieg, 1986a;Stępie n & Błażewicz-Paszkowycz, 2013), but also occur in or on a variety of different substrata, e.g., sand, silt clay, rubble, algae, or dead corals (Table 1).…”

On the Authorship of the Genus-group Name <i>Curtipleon</i> (Crustacea: Tanaidacea: Metapseudidae)

“…The tanaidacean genus Curtipleon Bǎcescu, 1976 consists of five species inhabiting the tropical Indian Ocean and eastern Australia (Stępień and Błażewicz-Paszkowycz 2013). Bǎcescu (1976b) originally erected this genus-group name for two nominal species, Synapseudes carinatus Makkaveeva, 1971 from the Red Sea (Makkaveeva 1971) and S. carinatoides Bǎcescu, 1976 from Tanzania (Bǎcescu 1976a), but did not designate a type species for the genus, as is required for availability under Article 13.3 of the International Code of Zoological Nomenclature (hereinafter, Code; International Commission on Zoological Nomenclature 1999).…”

“…Later, Sieg (1983) selected S. carinatoides as the type species for this genus-group name, although type fixation by subsequent designation is only valid for genus-group names proposed before 1931 (Article 60 of the Code). Workers thereafter followed Sieg's nomenclatural treatment of Curtipleon and treated this genus-group taxon as both available (from Bǎcescu 1976b) and valid (e.g., Larsen 2002;Bamber 2008;Stępień and Błażewicz-Paszkowycz 2013;Heard et al 2018).…”

“…Included species. Curtipleon carinatoides (Bǎcescu, 1976); Curtipleon carinatum (Makkaveeva, 1971); Curtipleon chadi Stępień and Błażewicz-Paszkowycz, 2013; Curtipleon heterochelatum Larsen, 2002; Curtipleon loerzae Bamber, 2008. Remarks. When he proposed this genus, Bǎcescu (1976b) cited one of the included species with a masculine ending, in the combination Curtipleon carinatus.…”
