- Description: The Australian Orchesellidae includes only 11 nominal species in four genera: Australotomurus Stach, 1947, Alloscopus Börner, 1906, Heteromurus Wankel, 1860, and Falcomurus Mandal, 2018. Here we describe Dicranocentrus dolosus sp. nov. from Cocos and Keeling Islands, the first species of the genus to be recorded from Australia. The new species is similar to D. inermodentes (Uchida, 1944) and D. indicus Bonet, 1930, but differs from both by the combination of the ventral head, mesothoracic and dental chaetotaxy. We also revisit Australotomurus based on previous studies to better interpret the dorsal macrochaetotaxy of the genus, and provide a synthetic map of chaetae to guide future studies on scaleless Orchesellidae. Finally, we present updated diagnoses to all genera and species of Australian Orchesellidae, as well as an identification key to all species. © 2022 Magnolia Press.

- Description: Soil-dwelling Entomobryomorphan Collembola from the Northeast of Iran were sampled for the first time as part of a biodiversity surveying study with the aim of improving ecosystem conservation. Materials were obtained by sampling in three different ecosystems including forest, rangeland and agricultural fields between 2018 and 2019. The specimens were cleared using either Nesbitt’s fluid or lactic acid and permanent microscopic slides were prepared using Hoyer’s medium. As the result of this study, twenty-nine species belonging to twenty-two genera and five families of the order Entomobryomorpha were identified. Among them, two genera and eight species are recorded for the first time from Iran. The new records are Desoria trispinata (MacGillivray, 1896), Drepanosira hussi Neuherz, 1976, Heteromurtrella sp., Orchesella flavescens (Bourlet, 1839), Willowsia bartkei Stach, 1965, Agrenia sp., and Isotomiella gracilimucronata Rusek, 1981.

- Description: We examined the density, diversity, and seasonal fluctuation of soil inhabiting Collembola in different ecosystems: agricultural, rangeland, and forest ecosystems in the North Khorasan province of Iran from June 2018 to May 2019. The sampling program was conducted monthly on the three sites. Density was measured on the number of individuals per square meter. Species diversity was calculated using Shannon–Wiener index, Simpson’s diversity, and species richness by Rarefaction method. Fifty-three species belonging to 42 genera and 17 families were collected and identified. The density of Collembola in the forest was higher than in either rangeland or agroecosystem. Highest densities were recorded during October and April in the forest. A similar seasonal trend was observed in the rangeland and in the agroecosystem. The lowest densities in agroecosystem and rangeland were recorded during June and from forest in January. PERMANOVA analysis showed that the soil Collembola community differed between the three ecosystems. The SIMPER analysis revealed that the agriculture sites show the highest similarity (68.3), followed by pasture (51.8), and then forest (49.7). Indices of diversity and species richness values are discussed in light of land use. We found that forest harboured a higher density and diversity of Collembola compared to rangeland and agroecosystems. © TÜBİTAK.

- Description: The onychiurid fauna of Australia is revised and found to comprise six species belonging to five genera. All species are already described and are widespread in the Northern Hemisphere so they are considered to be introduced to Australia. For the most part, they are only known in Australia from agricultural and horticultural soils and home gardens as well as worm beds. A dichotomous key to the species is presented together with updated names, relevant synonymies, a brief description of each and comments on their distribution and ecology. The six species separated in the key are Protaphorura fimata (Gisin, 1952), Thalassaphorura encarpata (Denis, 1931), Thalassaphorura cryptopyga (Denis, 1931), Orthonychiurus folsomi (Schäffer, 1900), Deuteraphorura cebennaria (Gisin, 1956) and Onychiurus ambulans (Linnaeus, 1758). A seventh species is listed here but in family Tullbergiidae, Metaphorura affinis (Börner, 1902). It is included as it could be confused with the Onychiurinae in the field. In Australia and overseas, onychiurids have been associated with root damage to plants in home gardens and field crops, and we discuss their pest status using data from assessments of field crop damage in Australia. The aim of this paper is to provide an identification guide to field workers so that they can decide whether control methods are required. © 2022 The Authors.

- Description: The pan-Antarctic distributions of several collembolan species have been supported by morphology for over 120 years. However, for most species where molecular data are available, these are now known to belong instead to several species, and most classified as short-range endemics. One such species, Friesea grisea, had a pan-Antarctic distribution that has been in question, but until recently, specimens of F. grisea from the type locality on South Georgia have not been included in any molecular appraisal. Here, we compare the molecular identity of specimens of F. grisea, from South Georgia, with other Antarctic and sub-Antarctic species using the mitochondrial COI gene. A Bayesian phylogenetic analysis for 14 species of Friesea from southern regions, including F. grisea sensu stricto with species previously identified as ‘F. grisea’ (F. antarctica, F. gretae and F. propria) confirms the distinctness of the South Georgian specimens based on molecular data, and these results are confirmed morphologically. The genus Friesea is one of the most speciose genera of Collembola known in the Antarctic region, and we provide an annotated key (dichotomous and interactive versions) to all Friesea species in the sub-Antarctic and Antarctica. We compare the biogeography of Friesea to other Collembola from the region to highlight our current understanding of species boundaries and island linkages. © 2021 Royal Swedish Academy of Sciences.

- Description: Falcomurus Mandal is currently a monotypic genus of Heteromurinae described from India in 2018. Its key characters are the first antennal segment subdivided, the second undivided and the third annulated, the first abdominal segment lacking macrochaetae, and the presence of a sinuous modified macrochaeta on the proximal dens. Some details of its morphology were recently put in doubt, and so its genus status and affinities remain uncertain. Here, we revise the genus based on the type material of Dicranocentrus litoreus Mari-Mutt, as well as provide the description of two new species from Australian archipelagos and a reinterpretation of the chaetotaxy of Falcomurus chilikaensis Mandal and D. halophilus Mari-Mutt. After our revision, Falcomurus shows a well-conserved chaetotaxy and overall morphology, which allowed us to provide an updated generic diagnosis. While the antennae morphology of Falcomurus resembles that of Dicranocentrus Schött, its dorsal sensillar and macrochaetotaxy suggest it is closely related to HeteromurusWankel, as originally stated by Mandal. The main features useful to separate Falcomurus species are the head, mesothorax and fourth abdominal segment chaetotaxy. We also provide a key to its five species, a comparative table and notes on the affinities and distribution of Falcomurus. © 2021 by the authors.

- Description: Originally the genus Entomobrya (Collembola: Entomobryidae) comprised 25 species names in Australia including 7 subspecies of which 13 were exotic (50%) and the rest native. All native species had been either described by H. Schött or H. Womersley and had not been examined since 1942. Specific characters they used were few, mainly colour pattern and gross morphological features such as unguis, unguis teeth and mucronal form. Chaetotaxic characters have now been developed. We now here recognise 47 species of Australian Entomobrya and Hymalanura based on a large collection made over 50 years. Six species (12%) are now recognised as introduced, 37 are new and three unresolved because of lack of specimens in good condition. Detailed descriptions and figures are supplied. Several new species are short-range endemics of conservation significance, others are specialised as to habitat, but most are widespread. Entomobrya is now the most species rich genus of Australian Collembola. A phylogenetic tree based on morphological and biological characters revealed clusters of exotic and montane habitat specialists, indicating that the genus is paraphyletic and so confirms other authors' work based on molecular characters. A key is supplied to Australian genera of Entomobryomorpha. A new genus record, Himalanura, is recognised extending its range to the Southern Hemisphere and 5,000 km further southeast. © 2020 Magnolia Press.

- Description: The invertebrate terrestrial fauna of Antarctica is being investigated with increasing interest to discover how life interacts with the extreme polar environment and how millions of years of evolution have shaped their biodiversity. Classical taxonomic approaches, complemented by molecular tools, are improving our understanding of the systematic relationships of some species, changing the nomenclature of taxa and challenging the taxonomic status of others. The springtail Friesea grisea has previously been described as the only species with a “pan-Antarctic” distribution. However, recent genetic comparisons have pointed to another scenario. The latest morphological study has confined F. grisea to the sub-Antarctic island of South Georgia, from which it was originally described, and resurrected F. antarctica as a congeneric species occurring on the continental mainland. Molecular data demonstrate that populations of this taxon, ostensibly occurring across Maritime and Continental Antarctica, as well as on some offshore islands, are evolutionarily isolated and divergent and cannot be included within a single species. The present study, combining morphological with molecular data, attempts to validate this hypothesis and challenges the taxonomic status of F. antarctica, suggesting that two additional new species, described here as Friesea gretae sp. nov. and Friesea propria sp. nov., are present in Continental Antarctica. © 2020 by the authors.

Hemilobella matildae sp. nov. Smolis and Greenslade is characterised by elongated tubercles laterally on body and an elongated ogival labrum. Sphaeronura ameliae sp. nov. Smolis and Greenslade differs from other taxa in the genus in chaetotaxic features and the presence of a male ventral organ. A new record of Australonura scoparia is included. The high species richness of lowland rainforests, in which these log inhabiting saproxylic species were found, is noted, and the contribution that extreme events such as cyclones in maintaining the fallen timber habitat is emphasised. The bright colour of these species may be caused by sequestered pigments from the slime moulds on which they feed. The colour probably also acts as a warning to predators that individuals are distasteful. A description of the distributions, characteristics, distinctiveness and possible genesis of Australian fauna of the subfamily Neanurinae is presented, and a checklist of species and key to all Australian genera of the subfamily is included. Species in this subfamily are predominately short-range endemics so should be surveyed whenever wet forests are under threat from logging or urban expansion. © 2020 Australian Entomological Society

- Description: Collembola are a basal group of Hexapoda renowned for both unique morphological characters and significant ecological roles. However, a robust and plausible phylogenetic relationship between its deeply divergent lineages has yet to be achieved. We carried out a mitophylogenomic study based on a so far the most comprehensive mitochondrial genome dataset. Our data matrix contained mitogenomes of 31 species from almost all major families of all four orders, with 16 mitogenomes newly sequenced and annotated. We compared the linear arrangements of genes along mitochondria across species. Then we conducted 13 analyses each under a different combination of character coding, partitioning scheme and heterotachy models, and assessed their performance in phylogenetic inference. Several hypothetical tree topologies were also tested. Mitogenomic structure comparison revealed that most species share the same gene order of putative ancestral pancrustacean pattern, while seven species from Onychiuridae, Poduridae and Symphypleona bear different levels of gene rearrangements, indicating phylogenetic signals. Tomoceroidea was robustly recovered for the first time in the presence of all its families and subfamilies. Monophyly of Onychiuroidea was supported using unpartitioned models alleviating LBA. Paronellidae was revealed polyphyletic with two subfamilies inserted independently into Entomobryidae. Although Entomobryomorpha has not been well supported, more than half of the analyses obtained convincing topologies by placing Tomoceroidea within or near remaining Entomobryomorpha. The relationship between elongate-shaped and sphericalshaped collembolans still remained ambiguous, but Neelipleona tend to occupy the basal position in most trees. This study showed that mitochondrial genomes could provide important information for reconstructing the relationships among Collembola when suitable analytical approaches are implemented. Of all the data refining and model selecting schemes used in this study, the combination of nucleotide sequences, partitioning model and exclusion of third codon positions performed better in generating more reliable tree topology and higher node supports than others. © 2020 Sun et al.

- Description: 'Temeritas regalis' (Womersley, 1939) was formerly common in the Mt Lofty Ranges extending from as far north as Alligator Gorge/Mt Remarkable/Wirrabara in the Southern Flinders to Myponga, 60 km south of Adelaide. The species is a South Australian endemic and belongs to a pantropical wide genus. It was collected several times in the 1930's and fourteen times in the 1970's but it has not been seen since 1978. In spite of collecting efforts from its typical habitat in the Mt Lofty Ranges and Southern Flinders Ranges and at Mt Bold on 21 occasions in the last 20 years, no further specimens have been found. It appears that populations have shrunk in size or may have disappeared altogether since the 1980s due to a number of factors mainly: climate change, drought, habitat alteration and/or expansion of invasive plants, invertebrates and 'Phytophthora'. Consequently, it is suggested that the apparent population decrease and possible local extinctions are real and, as a result, this species complies with the IUCN criteria A1 and B, and should be listed as endangered under the South Australian legislation.

- Description: Offshore islands are often important in conservation because of the presence of locally endemic species and for acting as refuges for native wildlife from the impacts of invasive species and inappropriate development. Barrow Island, a small, semi-arid island off the Pilbara coast of northwestern Australia, has maintained the integrity of its terrestrial and aquatic biota despite sporadic incursions by invasive species and the operation of commercial oil extraction and liquified natural gas processing for over 50 years. We collate information from a wide range of sources to provide a framework to inform the ongoing management of the terrestrial and aquatic fauna and flora species that have conservation significance on the island. These include endemic flora and fauna; species listed as threatened by state, national and international authorities; species that are rare or extinct in other parts of their original range; species of biogeographic significance; and migratory birds and marine fauna of national and international significance. In addition, Barrow Island has been of value in acting as a source area for translocations of vulnerable and endangered mammal species that have been eradicated in other parts of their range. The many species with conservation significance and their use in successful translocation programs demonstrates the island’s national and international importance for conservation. In addition, Barrow Island provides exemplary opportunities for research on effective co-management of development and conservation, on mitigation and prevention of the invasion and impacts of exotic species, and on the influence of historical biogeographic processes on the distributions and evolution of biota. © Royal Society of Western Australia 2019.

- Description: Biological invasions are one of the major threats to Antarctic native biodiversity and to ecosystems integrity. Regional environmental change and increasing human activity in Maritime Antarctica facilitates the introduction, establishment and colonisation of an increasing number of non-indigenous species. Systematic monitoring is an essential tool for the early detection of the arrival of non-indigenous arthropods. In this study, we compiled the results of a long-term monitoring effort from 2011 to 2017 to survey non-native collembolan species on Deception Island, a highly visited terrestrial site in South Shetland Islands (Maritime Antarctica). Results include the first record of Ceratophysella succinea (Gisin) (Hypogastruridae) in Antarctica. Moreover, the global dataset indicates that the total number and the list of cumulatively occurrence localities for non-native species observed on the island has increased over this monitoring period. This suggests that repeated monitoring is advisable to characterise the full extent of microarthropod introductions into a high biosecurity risk area and improve the effectiveness of surveillance efforts.
