We provide an overview of the World Amphipoda Database (WAD), a global species database that is part of the World Register of Marine Species (WoRMS). Launched in 2013, the database contains entries for over 10,500 accepted species names. Edited currently by 31 amphipod taxonomists, following WoRMS priorities, the WAD has at least one editor per maj...

An annotated checklist of the marine amphipods recorded from Indian waters is compiled from the available peer-reviewed literature. A total of 266 species belonging to 133 genera and 56 families are listed. The maximum numbers of species were recorded from the South Indian Ecoregion (177 species, 98 genera, 47 families), followed by the Western Ind...

A new species of Glossocephalus, G. aurantium sp. nov., is described based on two female specimens collected from the Monterey Canyon, California, eastern Pacific Ocean. It was found associated with an undescribed lobate ctenophore. Glossocephalus aurantium is readily distinguished from its congeners by the large crescent-shaped bulbous eye fields...

Megalanceoloides remipes is a rare deep-sea species known from very few specimens. Until recently (Zeidler 2019) it was known only from the type, an incomplete female, and one other specimen, probably a juvenile female (Vinogradov 1964). Another specimen, an ovigerous female, described by Gasca & Haddock (2016) and compared to the previous two, was...

This is the first comprehensive taxonomic review of the family Lycaeidae. This study is based primarily on the extensive collections of the Natural History Museum, Denmark (NHMD, formerly ZMUC) and the US National Museum of Natural History, Smithsonian Institution, Washington DC, USA (USNM), and on additional material from the South African Museum...

Lanceola loveni antarctica and L. sphaerica are rare deep-sea species known from very few specimens. Until recently (Zeidler 2019) L. loveni antarctica was known only from the types, seven specimens (7–27 mm), from the Indian Ocean Sector of the Antarctic (Vinogradov 1962). Similarly, L. sphaerica, originally described as a variety of L. clausi (Vi...

This is the first comprehensive taxonomic review of the family Brachyscelidae. The family is currently mono-generic following the review of Zeidler (2016). There are 17 nominal species referable to the genus Brachyscelus in the literature including two old references to species that most likely represent species of Brachyscelus. However, most are r...

New and additional records of hyperiidean amphipods of the infraorder Physosomata from the Antarctic Zone of the Southern Ocean, based on specimens in the USNM, are documented. They represent several range extensions for species previously recorded from the region as well as 14 new records with another three recorded from within a few degrees north...

The hyperiidean amphipod Brachyscelus rapacoides Stephensen, 1925 is recorded from the scyphozoan jellyfish Rhopilema nomadica Galil, 1990, a new record of association for the genus Brachyscelus, as well as the first record of hyperiid infestation of a non-indigenous scyphozoan host. Because of some past confusion concerning the status of B. rapaco...

Hyperiidean amphipods are a major prey for fish and seabirds. In the Southern Ocean, they are particularly abundant, with distributions ranging from the Polar Frontal Zone to Antarctic shelf waters. The species Hyperiella dilatata has previously been reported to show a peculiar anti-predatory behaviour: It captures chemically protected, gymnosome p...

The generic name Euscelus was originally proposed by Schoenherr (1833: 205) for a genus of Leaf Rolling weevils (Insecta: Coleoptera: Attelabidae). It is a valid name, in current use, for a relatively large genus of weevils, widespread in northern South America and central America, including the West Indies and the Caribbean (e.g. Hamilton 2007; Le...

The systematics and phylogenetic relationships of the families and genera of the superfamily Platysceloidea are examined, following a thorough examination of the morphology of an example of the type species of each genus, or a substitute species if the true identity of the type species is in doubt. The mouthparts are described for each type species...

Very large swarms of the red jellyfish Crambione mastigophora in north-western Australia disrupt swimming on tourist beaches causing economic impacts. In October 2012, jellyfish stranding on Cable Beach (density 2.20 ± 0.43 ind. m-2) was estimated at 52.8 million individuals or 14,172 t wet weight along 15 km of beach. Reports of strandings after t...

A new species of Glossocephalus, G. rebecae sp. nov., is described from deep-water in the Monterey Bay region of California, Eastern Pacific Ocean. It seems to be associated exclusively with the mesopelagic ctenophore Bathocyroe fosteri. This association has been observed from 541–830 m depth. It is readily distinguished from G. milneedwardsi Boval...

This is the first comprehensive review of the genus Hyperoche since that of Bovallius (1889). This study is based primarily on the extensive collections of the ZMUC but also on more recent collections in other institutions. Seven valid species are recognised in this review, including one described as new to science. Two new characters were discover...

A taxonomic review of the hyperiidean amphipod families Mimonectidae and Proscinidae, superfamily Sciniodea, is presented, based predominantly on collections held by the Zoological Museum, University of Copenhagen, Denmark. Prior to this review the family Mimonectidae consisted of two genera, Mimonectes with five species and Pseudomimonecteswith on...

A new species of Mimonecteola, M. antarctica sp. nov., is described from two specimens collected by the R/V Eltanin from the Amundsen Sea (Pacific Sector) and north-west of Elephant Island (Atlantic Sector). It is most similar to M. carlsbergi Zeidler, 2009 but is readily distinguished by the relatively shorter, and more feeble, fifth pereopoda and...

An unusual new species of narcomedusa from Tasmania is described. It differs from all other species of narcomedusae in having two whorls of tentacles, as well as a beveled opening in the apical surface containing peculiar 'sky-scraper-like' protruding structures, which we have interpreted as gonads. We place this unusual form in its own family, the...

An overview of the Ctenophora of Australia is presented based on limited collecting efforts, together with the description of seven species new to science. Euplokamis evansae sp. nov. (Cydippida: Euplokamididae), has only been found in Tasmanian waters; it is distinguished from its congeners in the comb rows being about 4/5 of the body length, the...

The medusae (Scyphozoa, Cubozoa, Hydrozoa, including Siphonophora) of Moreton Bay are reviewed based on recent collections and literature records. Seven new species are described. Euphysora juliephillipsi sp. nov. differs from its congeners in having a long narrow apical projection with complete apical canal, moniliform main tentacle with a termina...

A taxonomic review of the superfamily Lanceoloidea is presented, based predominantly on collections held by the Zoological Museum, University of Copenhagen, Denmark. Prior to this review the superfamily consisted of three families, Lanceolidae with five genera, Chuneolidae with one genus and Microphasmidae with three genera. The family Lanceolidae...

The generic name Clarencia was originally proposed by Sloane (1917) for a genus of carabid beetles ( Insecta, Coleoptera, Carabidae). It is a valid name in current use for a small endemic genus of Australian/Papua New Guinean ground beetles, recently revised by Baehr (2005). Clarencia K. H. Barnard, 1931, was established as a monotypic genus of Ant...

Cladonema timmsii, sp. nov., is described from Blue Lagoon, an inland saline lake on Eyre Peninsula, near Cactus Beach, due south of Penong, Australia. It is a small medusa with a bell height and diameter of about 2.0mm. It differs from its congeners in having (1) sexually dimorphic gonads, i.e., the males bearing six radially arranged gonadal pouc...

A taxonomic review of the families and genera of the hyperiidean amphipod superfamily Phronimoidea is presented. The systematic relationship of genera is examined in detail. The current genera seem to be well-defined taxonomic units but some such as Themisto and Hyperoche are in need of thorough taxonomic revision. The genera of the families Phroni...

A taxonomic review of the superfamily Lycaeopsoidea is presented. The superfamily currently consists of one family represented by one genus with two species. A detailed morphological examination of many specimens, of both species, supports the superfamily status, based on the extreme sexual dimorphism and characters of the antennae and mouthparts u...

Australomedusa thrombolites sp. nov. is described from Lake Clifton, Yalgorup National Park. It is a small medusa with a bell height (BH) of about 1.5 mm. It differs from its only other congener, A. baylii, primarily in the shape and location of the gonads, and in having only 3–5 tentacles per cluster (verses 5–9). Furthermore, in preserved specime...

The medusae and ctenophores of the Nuyts Archipelago are reported for the first time. In all, the collection includes at least 17 species of Hydromedusae (eight described here as new to science), one species of Siphonophorae, one species of Scyphomedusae, and two species of Ctenophora (one possibly new to science). The localized evolutionary radiat...

A taxonomic review of the hyperiidean superfamily Vibilioidea is presented, based on material held by most of the major museums in the world. Three families are recognised as belonging to the superfamily. It is proposed to remove Cyllopus from the family Vibiliidae, based on the positioning of the antennae and other minor characters inconsistent wi...

A taxonomic review of the hyperiidean amphipod family Cystisomatidae is presented, based on material held by most of the major museums in the world. A new superfamily, Cystisomatoidea, is proposed to accommodate the family Cystisomatidae, based on the unique method of brooding the young, the remnant second antennae in both sexes, and other minor ch...

A taxonomic review of the genus Oxycephalusis provided with a key to species. Only three species are recognised in this review:O.piscatorMilne-Edwards, 1830, O.latirostris Claus, 1879 and O.clausi Bovallius, 1887. The systematic limits of these three species are redefined and clarified and all species are illustrated. O.longipes Spandl, 1927 is sho...

A revised diagnosis for the family Anapronoidae is provided. The only previously described species Anapronoe reinhardti is redescribed and a new species, A. bowmani sp. nov., from off California is described. The orientation of the second antennae of the male, folded diagonally across the head, is unique amongst the Hyperiidea.

Most of the collection of Crustacea of the nineteenth century French naturalist Guérin-Méneville (1799-1874), is held in the General Invertebrates Collection of the Academy of Natural Sciences of Philadelphia. This paper lists the hyperiid amphipods from that collection, together with notes on their systematic status. Illustrations are given for ma...

A freshwater amphipod Austrochiltonia dalhousiensis sp. nov. is described and illustrated. It is endemic to a few artesian springs amongst the Dalhousie Springs complex in the north of South Australia. Morphologically it is very similar to other species of Austrochiltonia found in mound springs near Lake Eyre South but preliminary electrophoretic a...

The status of Typhis rapax H. Milne Edwards, 1830, has been uncertain due to the brief original description and lack of illustrations. Stephensen (1925) having examined a specimen labeled T. rapax, presumably from the collection of Milne Edwards, determined that it was the same as Hemityphis tenuimanus Claus, 1879. This synonymy has been accepted b...

An examination of fresh material of Clarencia chelata K. H. Barnard, 1931, collected from the Prydz Bay region, Antarctica, has revealed a number of characters not recognised previously or diagnosed incorrectly. New morphological information is provided and the systematic position of Clarenciidae is re-evaluated and a new superfamily Clarencioidea...

A new species of pelagic amphipod, Lestrigonus ducrayi sp. nov., from eastern Australia, is described and illustrated. It is very similar to Lestrigonus bengalensis Giles, 1887, but is readily distinguished by a relatively shorter telson (about one-third peduncle uropod 3) and, in mature males, pereonites 1–5 are fused as in females. The two specie...

The Australian freshwater crayfish genus Gramastacus, previously consisting of two species known only from type localities, is revised utilising newly collected material ranging from The Grampians, Victoria, to the south-east, of South Australia. Morphological and biochemical studies demonstrate that Granzastacus is monotypic with G. insolitus Riek...

Hyperiid amphipods (35 species) were collected at eight regular sampling stations, spaced evenly between Townsville and the Great Barrier Reef, over 1 year (October 1972 to October 1973). The distribution and abundance of the Hyperiidea in northern Queensland, where hyperiids were generally most abundant during October-December and April-July, are...

Plankton samples collected between Townsville and the Great Barrier Reef during the period from October 1972 to October 1973 were subsampled for hyperiid amphipods. Thirty-five species of Hyperiidea representing 10 families and 26 genera were found. Twenty-two species are new records for the Great Barrier Reef region and 16 are new records for Aust...
