On the Mysid crustacean genus Heteromysis (Mysidae: Heteromysinae) of the Tasman Sea, with notes on the tribe Heteromysini

James K. Lowry (1942Lowry ( -2021 was one of the most prolific crustacean taxonomists of the late 20th through early 21st century, authoring some 214 publications over a period of some 55 years in which he named some 800 new taxa including 5 suborders, 62 families, 129 genera, and 548 species of primarily amphipod crustaceans. The present work provides a complete list of Jim Lowry's scientific publications along with the new taxa that he described therein.

“…Another two potential generic diagnostic characters, found in D. lowryi sp. nov., but not studied in other heteromysids, except in the genus Heteromysis, are the overlap of the posterolateral lobes of the abdominal segment 6 (Figs 2F, 6E), not overlapping in Heteromysis (Daneliya, 2021), and the presence of the subapical wing-like extensions on the maxilliped 1 dactylar claw (Figs 4A, 7E). Panampunnayil & Biju (2007) distinguished the genus Kochimysis from Deltamysis on the basis of the male lobe presence on the antennular peduncle, the articulation absence on the antennal scale, the presence of the lacinia mobilis on the mandible and the wide segment 2 of the mandibular palp, equal size of the maxilla 2 endopod segments and the oval shape of its segment 2.…”

“…In the current paper I report about the second part on the subfamily Heteromysinae Norman, 1892, dedicated this time to the genus Deltamysis Bowman & Orsi, 1992, of the tribe Mysidetini Holt & W. M. Tattersall, 1906. In the first part, on the genus Heteromysis S. I. Smith, 1873, published in the same journal (Daneliya, 2021), after the revision of Heteromysoides Băcescu, 1968 (tribe Heteromysini Norman, 1892) I also transferred H. nana Murano, 1998, andH. songkhlaensis Yolanda, Sawamoto &Lheknim, 2019, to Deltamysis. Here I describe a new species, D. lowryi sp.…”

On the mysid crustacean genus Deltamysis (Mysidae: Heteromysinae), with a new species and a new record from Australia

Daneliya

2023

The genus Deltamysis, in the tribe Mysidetini (Mysidae: Heteromysinae), previously contained a single species, D. holmquistae, before two additional species, D. nana and D. songkhlaensis, were transferred from Heteromysoides of the related tribe Heteromysini. A new member of the genus, D. lowryi sp. nov., found at the mouth of the Clarence River, New South Wales, in 1988, is described here from the Australian Museum collection. The collection also contained two specimens of D. holmquistae from the eastern Australian coasts of the Coral Sea and the Tasman Sea, not previously recorded from Australia. Deltamysis lowryi sp. nov. differs from the other three species of the genus by the structure of the telson, which has a wide, shallow cleft, armed with a number of spinules, and notably shortened subterminal spiniform setae. The diagnosis and the generic composition of the tribe Mysidetini, and the diagnoses of the genus Deltamysis and all its four species are updated. Deltamysis has so far been the only genus of the marine subfamily Heteromysinae diversifying in brackish estuarine water. The genus has a clear western Indo-Pacific natural occurrence, but has been introduced also to the Eastern Pacific and more recently to the Atlantic coasts of North America.

“…Deep-water mysids of the southeast Australia have different origin compared to the shallow-water mysids of this area. The latter are related to the tropical West Indo-Pacific fauna (Daneliya, 2021). The deep-water fauna has not been affected by the currents and general climate of the ocean surface, which provided relatively isolated favourable conditions for the existence and development of the ancient mysid subfamily Boreomysinae.…”

Mysid subfamily Boreomysinae (Crustacea: Mysida: Mysidae) in the southeast Australian deep-sea

Daneliya¹

2023

The deep-water mysid crustaceans of Australia have been barely known. Recent explorations of RV Investigator (CSIRO) in the southeast Australian waters discovered a unique fauna. In this special study of the marine subfamily Boreomysinae (family Mysidae) in Australia, five species from both genera Boreomysis and Neobirsteiniamysis are reported, including two new species for science: B. inopinata sp. nov., B. sibogae, B. sphaerops, B. urospina sp. nov. and N. inermis. Among the members of the subfamily, only B. sibogae has been previously known from Australia. The genus Neobirsteiniamysis and its bipolar-amphitropical species N. inermis are firstly recorded in Australia. Boreomysis inopinata sp. nov. has additional spinules on the outer spine of the antennal scale, which are not found in other species of the subfamily. Boreomysis urospina sp. nov. has the longest first segment of the uropodal exopod, laterally terminated by three spiniform setae; and its uropodal endopod is armed with up to five medial spiniform setae, the largest number in the subfamily. This species is included in a newly established subgenus Petryashovia subgen. nov., which unites epi-mesopelagic boreomysines, lacking the rostral projection, having rather small ventrolateral lobes of the carapace, and the 1-segmented propodus of the pereopods. The subfamily and generic diagnoses are updated. Additionally, a fragment of the mtDNA COI gene was sequenced for most of the studied species.
