A Phylogeny and Classification of the Amphipoda with the establishment of the new order Ingolfiellida (Crustacea: Peracarida)

A classification is proposed for the order Amphipoda. The Amphipoda includes six suborders, the Pseudingolfiellidea, Hyperiidea, Colomastigidea, Hyperiopsidea, Senticaudata (described in a previous contribution (Lowry & Myers 2013)) and Amphilochidea. The suborder Ingolfiellidea is raised to order status. A cladistic tree, based on morphology, is presented illustrating the relationships of the Amphipoda at parvorder level. A tree for the families of the Physomatidira and Physocephalatidira, a tree for the Maxillipiidira, Oedicerotidira, Eusiridira and Amphilochidira and a tree for the Synopiidira, Haustoriidira and Lysianassidira, are provided. Families are listed together with their included genera. New families are diagnosed.

Redescriptions of Schellenberg's types of Lysianopsis subantarctica and Paralysianopsis odhneri (Amphipoda, Lysianassidae)

Schellenbergs types of Lysianopsis subantarctica and Paralysianopsis odhneri are redescribed. Lysianopsis subantarctica is shown to be closely related to L. holmesi (J. L. Barnard). The genus Paralysianopsis is rediagnosed and placed in the family Lysianassidae sensu stricto.

A new south american genus and species in the amaryllidid group of lysianassoid Amphipoda

Erikus dahli, a new genus and species in the amaryllidid group of lysianassoid amphipods, is described and illustrated from South American material.

New species of Floresorchestia from Micronesia living in unusual habitats (Crustacea, Amphipoda, Talitridae)

The first freshwater talitrid, Floresorchestia pohnpei sp. nov., is described from the island of Pohnpei, Micronesia. Floresorchestia palau sp. nov. is described from supralittoral and shallow-water marine habitats in Palau, Micronesia.

The genus Elasmopus (Crustacea: Amphipoda: Maeridae) in Australian waters

Eight new species and one new record of Elasmopus Costa, 1853 are described from Australian waters including the extended offshore territories of Cocos (Keeling) Islands (Indian Ocean), Christmas Island (Indian Ocean), Ashmore Reef (Timor Sea), Norfolk Island (Tasman Sea) and Lord Howe Island (Tasman Sea). Range extensions are reported for seven described Australian species. Twenty-three species are now known from Australian waters. Elasmopus arafura sp. nov., E. carteri sp. nov., E. hyperopia sp. nov., E. leveque sp. nov., E. mcluerensis sp. nov., E. otus sp. nov., E. shepherdi sp. nov. and E. woodjonesi sp. nov. are described herein.

The tropical talitrid genus Floresorchestia (Crustacea, Amphipoda, Talitridae).

Floresorchestia floresiana (Weber, 1892) from Flores, F. anomala (Chevreux, 1901) from the Seychelles, F. malayensis (Tattersall, 1922) from Singapore and F. thienemanni (Schellenberg, 1931) from Java are redescribed based on original type material or newly collected material from near the type locality. Nine new species are described, in the widespread Indo-West Pacific and Caribbean talitrid genus Floresorchestia: F. andrevo sp. nov. and F. itampolo sp. nov. from Madagascar; F. kalili sp. nov. from the Bismarck Archipelago, Papua New Guinea; F. laurenae sp. nov. from Timor-Leste; F. oluanpi sp. nov. from southern Taiwan; F. papeari sp. nov. from Tahiti; F. serejoae sp. nov. from far north Queensland, Australia; F. seringat sp. nov. from Singapore; and F. yap sp. nov. from Micronesia; plus Floresorchestia sp. 1 from Hainan Island, South China Sea, Floresorchestia sp. 2 from Kilakarai and other sites in south-eastern India and Floresorchestia sp. 3 from Phuket Island, Thailand. Floresorchestia contains 28 species. In this paper all are catalogued and diagnosed.

The Tryphosa group (Crustacea: Amphipoda: Lysianassoidea: Lysianassidae: Tryphosinae).

The Tryphosa group is established within the tryphosine amphipods. It contains eight genera worldwide (Bruunosa Barnard & Karaman, 1987; Glorieusella gen. nov.; Gronella Barnard & Karaman, 1991; Metambasia Stephensen, 1923; Pseudonesimus Chevreux, 1926; Schisturella Norman, 1900; Thrombasia J.L. Barnard, 1966; and Tryphosa Boeck, 1871). As part of the Tryphosa group we describe the new genus Glorieusella from Madagascar and four new species (Schisturella rosa sp. nov., Thrombasia evalina sp. nov., Thrombasia umina sp. nov., Thrombasia saros sp. nov.) from eastern Australia.

A generic review of the lysianassoid family Uristidae and descriptions of new taxa from Australian waters (Crustacea, Amphipoda, Uristidae).

In this paper we review the genera of the family Uristidae and report for the first time from Australian waters: the new genus and species Des griffini; the genus Euonyx with two new species; Koroga megalops; the genus Parschisturella with three new species; and Stephonyx arabiensis plus one new species. We provide keys to species in the genera Abyssorchomene, Euonyx, and Parschisturella. Ten genera and 24 species of uristid lysianassoids are now known from Australian waters.

A new species of Cerapus from Cudjoe Channel, Lower Florida Keys, USA, with notes on male behaviour (Crustacea: Amphipoda: Corophioidea)

Cerapus cudjoe is described from Cudjoe Channel in the Lower Florida Keys, USA, where it lives primarily on the hydroid, Cnidoscyphus marginatus (Allman), in channels subject to strong tidal flow. The species is characterized by the shape of the palm of male gnathopod 2, and the huge peduncular hook on male uropod 1 which distinguishes it from all congeners. Males were observed swimming during slack tide and actively seeking females in presumed precopulatory behaviour.

A redescription of Cerapus tubularis say, 1817, based on material of the first reviewer, S.I. Smith, 1880, (Crustacea: Amphipoda: Corophioidea)

Cerapus tubularis Say, 1817, type species of the genus, is redescribed, based on material used by the first reviewer (Smith, 1880). Because of confusion concerning the identity of C. tubularis, a neotype is selected. The genus is redefined, based on the type species.
