The archaeological record of Wallacea remains exceptionally fragmentary. This is especially the case for late Holocene human occupation of the region when lifestyle and culture in marginal island environments is relatively unknown. Here we report on the archaeology of Jareng Bori rockshelter, a Metal-Age site spanning c. 1800 cal. BP up to the late historic period and situated on the eastern coast of Pantar Island in the Lesser Sunda Islands of eastern Indonesia. We use osteoarchaeological (human and vertebrate remains), invertebrate zooarchaeological (crustacean and molluscan remains), technological (lithics, shell, and pottery) and chemical sourcing (obsidian and metal) datasets to discuss networking, migration, and human subsistence strategies during this recent period of history. While some communities were no doubt living in open village settlements where they were producing pottery, the data indicate that aspects of maritime life-ways continued much as in earlier Pleistocene settlements, with people using rockshelters like Jareng Bori to pursue a range of subsistence activities focused on the shoreline. Shellfishing of rocky and reef intertidal species and fishing for mostly small herbivorous and omnivorous fishes was practised, while domestic animals only appear in the late historic period. Wider regional cultural interactions and networking are epitomized by obsidian exchange, dental modification practices, and pottery decorations, while lithic analyses indicates continuity of stone tool technology up until recent times.

Elucidation of the evolutionary history of the subgenus Mus, including the House Mouse Mus musculus, is essential to understanding species diversification mechanisms in the Indomalayan region, which is a global biodiversity hotspot. In terms of interspecific relationships, the topography of India, Myanmar, and other Southeast Asian regions has been proposed to explain the speciation process and ecological niche diversification followed by range overlap after speciation. Recent research into mitochondrial DNA clocks has created the opportunity to reconstruct the detailed dynamics of M. musculus as affected by human activity. The resultant evolutionary scenarios are in good accordance with archaeological evidence observed in Asia, especially in China, Korea, and Japan.

Two new species, Melinnopsis gardelli sp. nov. and Melinnopsis chadwicki sp. nov. (Annelida, Ampharetidae, Melinninae), are described from deep waters off the east coast of Australia. One hundred and 11 specimens were collected during RV Investigator voyage IN2017_V03 in May–June 2017 using a beam trawl at lower bathyal depths (1000–2500 m). This is the first record of Melinnopsis from the eastern Australian coast. The two new species are morphologically similar, but differ by methyl blue staining pattern, shape of thoracic uncini and pigmented glandular bands above the nuchal slits. Melinnopsis gardelli sp. nov. has a conspicuous stained band on the dorsum ending between chaetigers 9 and 10, uncini with three teeth above the rostral tooth and lacks glandular bands, while M. chadwicki sp. nov. has a faint stained band on the dorsum ending at chaetiger 5, uncini with two teeth above the rostral tooth and possesses glandular bands. They also show differences in bathymetric distribution as M. gardelli sp. nov. was collected around 2500 m and M. chadwicki sp. nov. around 1000 m depth. Phylogenetic relationships among the new species and other members of the family Ampharetidae were assessed using the nuclear 18S and the mitochondrial 16S and cytochrome oxidase subunit I (COI) gene fragments. The results revealed that M. gardelli sp. nov. and M. chadwicki sp. nov. form a monophyletic clade and are genetically distinct from each other and all other analysed species. This is the first time molecular data have been used to describe a species in the genus Melinnopsis.

The fauna of Ceriantharia (tube-anemones) in the South Pacific is poorly studied with only four shallow-water species formally described and these animals are known from few regions in very specific reports. Cerianthids are organisms that live in a tube constructed with a special type of cnidae and are currently grouped in an exclusive subclass of Anthozoa. This study addresses specimens from three natural history collections, the Australian Museum and the Museum and Art Gallery of the Northern Territory (both Australia), and the National Institute of Water & Atmospheric Research (NIWA) Invertebrate Collection (New Zealand), focusing on specimens from the Coral Sea, Tasman Sea and Antarctic Ocean. As a result, four new species are described and one synonymized. This highlights the ongoing need for taxonomic studies in the region, especially for marine organisms. Also, in this study, we offer tables with morphological characters that can be useful for species identification in each genus.

The systematic taxonomy of three currently accepted species of Austrochloritis Pilsbry, 1891 from central eastern New South Wales (A. nundinalis Iredale, 1943, A. niangala Shea & Griffiths, 2010, and A. kaputarensis Stanisic, 2010) is revised based on comparative morpho-anatomy and mitochondrial phylogenetics. In addition, the status of two undescribed candidate taxa identified as Austrochloritis spp. NE3 and SN39, respectively, is assessed. These species and candidate species are closely related to the type species of the genus, Austrochloritis porteri (Cox, 1866) from southern Queensland based on a recently published mitochondrial phylogeny. Comparative analyses of shell and reproductive anatomy revealed that the members of the A. porteri clade exhibit a rather similar morphology overall. Based on subtle, yet consistent differences in shell and reproductive features, we consider A. nundinalis as an accepted species. The species A. niangala, A. kaputarensis, and NE3 are considered as synonyms of each other and preference is given to the name A. niangala by First Reviewers Choice. The candidate taxon SN39 represents a new species, which is herein described as Austrochloritis copelandensis sp. nov.

Caprellids from mesophotic and deep-sea waters from Australia have been scarcely studied. A new genus Pseudoliropus gen. nov., and two new species Pseudoliropus keablei and Pseudoprotella australiensis sp. nov. are described based on material collected from 56 to 1125 m deep during surveys on board the vessels RV Sprightly (1973), FRV Kapala (1977–1986) and RV Southern Surveyor (2005) along the coast of the Northern Territory, Queensland, New South Wales, Victoria and Tasmania. Pseudoliropus is superficially very close to Liropus but can be readily distinguished by the absence of a mandibular molar (present in Liropus) and 2-articulate mandibular palp (3-articulate in Liropus). Pseudoprotella australiensis can be differentiated from all the remaining species of Pseudoprotella mainly on the basis of the unique body ornamentation (acute projection on the head, pereonites with abundant tiny tubercles scattered over the surface, and rows of lateral tubercles on the proximal end of pereonites 2–4). Further collections in deep ecosystems are mandatory to properly understand global amphipod diversity in Australian waters.
