This study recognises five Australian species of Hirsutonuphis, of which three are newly described; a key to adults is provided. Juvenile stages of the three new species, ranging from recently settled to near adult individuals, are described, with emphasis on the appearance and replacement of provisional and permanent hooks. Anterior pseudocompound hooks are generally preceded by compound falcigers. Two types of anterior provisional subacicular hooks, representing relict structures, occur in juveniles. Posterior provisional hooks, representing precursor subacicular hooks, occur in juveniles and the most posterior segments of adults. This study demonstrates that while setal progression in the genus shows species specific differences, it follows a pattern that is similar for allied genera but not identical for the whole family.

Three New Species

Australian mites in the genus Asca were last reviewed in 1956 when the first three Australian species were described. We here provide diagnoses for those species, describe three new species (Asca macromela, A. grostali and A. mindi) from the leaves of rainforest trees, and report on the occurrence in Australia of a species described from New Zealand (A. porosa Wood) and of a cosmopolitan thelytokous species (A. garmani Hurlbutt). Keys to the eight species and the three species-groups they represent are provided. Examination of 13 266 leaves from 193 species of woody plants in eastern Australian forests indicated that Asca mites are abundant and diverse inhabitants of tropical rainforest canopies, but decline in both diversity and abundance with increasing latitude.

Three new species of Aloninae cladocera from Central and South Brazil are described. Two of them, Acroperus tupinamba sp. n. and Alona yara sp. n., were previously recorded from the area as European taxa Acroperus harpae (Baird, 1834) and Alona quadrangularis (O.F. Müller, 1776), respectively. Acroperus tupinamba differs from the other species of Acroperus in smaller size, long posterior setae of the valves, shorter and wider postabdomen, short setules near the base of postabdominal claw, long apical spines of antenna, and peculiar morphology of limb IV exopodite. Alona yara differs from A. quadrangularis and A. kolweizii Van Damme & Dumont, 2008 in the number of ventral setules on ventral face of limb I, from A. boliviana Sinev et Coronel, 2006 in the shape of the body and postabdomen, narrow labral keel, and absence of projections on epipodites IV–V. The third new species, Celsinotum candango sp.n. differs from all other species of the genus in proportions of postabdomen. It differs from Australian species (C. hypsophilum Frey, 1991, C parooensis Frey, 1991, and C. platamoides Frey, 1991) in a less developed dorsal keel, lateral head pores located close to midline, longer spine on basal segment of antennal exopodite, and in the presence of extremely large projections on exopodites IV–V. Celsinotum candango differs from Brazilian C. laticaudatum Smirnov & Santos-Silva, 1995 in a shorter spine on basal segment of antenna exopodite, in the shape of postabdomen and in morphology of postabdominal denticles. At present, Aloninae fauna of Brazil includes 35 species, and true diversity is undoubtedly higher, with more new species to be expected in the country.

Species Specific

The collection of several paradoxosomatid species in the context of ecological studies prompted an investigation into the morphology and species-level characteristics of Australian millipedes in the tribe Australiosomatini Brölemann, 1916 (Polydesmida : Paradoxosomatidae). Three new species are described: Akamptogonus caragoon, sp. nov., Australiosoma fulbrighti, sp. nov. and Australiosoma combei, sp. nov. Notes or re-descriptions are provided for nine additional species belonging to the tribe. Scanning electron microscopy was utilised to examine details of the antennal sensory fields, the fifth sternite lamella and associated pores. The presence of the fifth sternite lamella in adult males is considered a synapomorphy for the family Paradoxosomatidae, whereas the prominent tubercle on the first femur in males (adenostyle) represents a synapomorphy of the subfamily Australiosomatinae. With the description of two new species in the genus Australiosoma Brölemann, 1913 a revision of the genus was undertaken with the purpose of constructing a species-level phylogeny. The most commonly described and utilised species-specific characteristics were scored in a data matrix and analysed using PAUP. The analysis resulted in a single, fully resolved tree of the following structure: Hoplatria clavigera ((A. clavigerum, A. inusitatum) (((A. rainbowi, A. nodulosum) A. michelseni) (A. laminatum (A. combei, A. fulbrighti))).

Sandy Sediments

The genus Aponuphis, previously known from the eastern North Atlantic and the Mediterranean, is newly reported from Australia. Three new species are described from off Sydney to Wollongong, New South Wales in sandy sediments, in depths of 25–70 m, bringing the number of recognized Aponuphis species to ten. Aponuphis annae n. sp. and A. bellani n. sp. are abranchiate, whilst A. danicae n. sp. has branchiae over a short region of its body. The tubes of A. annae and A. danicae have a fragile mucous consistency with attached sand grains and that of A. bellani is transparent, tight-fitting and smooth. Two specimens of A. annae were collected with developing juveniles in their tubes demonstrating their direct development but the reproductive mode of the other two species is not known. The distinguishing characteristics of all recognized species are tabled and a key to the three Australian species is presented.

In this review of Australian phreodrilid oligochaetes, several descriptions are amended, some species are reclassified and additional distribution data are provided for most species. One new genus (Nesodrilus) and 11 new species (Phreodrilus diemenensis, Phreodrilus melaleucensis, Phreodrilus mitodes, Antarctodrilus acanthaseta, Antarctodrilus micros, Antarctodrilus horwitzi, Nesodrilus southwellensis, Insulodrilus parviseta, Insulodrilus unisetoides, Insulodrilus bifidus and Astacopsidrilus myothyros) are described from Australia. Insulodrilus lacustris (Benham, 1903) is recorded in Australia for the first time, while Phreodrilus mauienensis Brinkhurst, 1971, and Astacopsidrilus campbellianus (Benham, 1909), comb. nov., are removed from the Australian species list. The latter is the first phreodrilid to be recorded on Macquarie Island. One new species, Insulodrilus novaezelandiae, is described from New Zealand and three new species, Antarctodrilus spinosus, Nesodrilus isochaeta and Astacopsidrilus beckettae, are described from Campbell Island. Aspects of phreodrilid zoogeography and anatomy are discussed.

The genus Lepidocyrtus Bourlet is currently considered to consist of eight subgenera of which Setogaster Salmon is one. Here we describe three new species in this subgenus, L. agricolus sp. nov., L. coorongensis sp. nov., and L. nashi sp. nov. It appears to be the most widespread and numerically dominant subgenus of Lepidocyrtus in Australia. The three new species live in different habitats and in different parts of the continent. It is assumed they are endemic species, one is likely to be a short range endemic. The characters and a list of species of the Lepidocyrtus praecisus-group, and an identification key for the Australian species of genus Lepidocyrtus are provided.

The phylogenetic relationships of 26 Australian species of Scirtes Illiger, Ora Clark and Exochomoscirtes Pic (Scirtidae) were investigated using adult morphology, particularly male and female genitalia, larval morphology and molecular data from the mitochondrial cytochrome c oxidase subunit I (COI) gene and the nuclear genes elongation factor 1-alpha (EF1- a) and topoisomerase I (TOP1). Four species of Scirtes and one of Ora from Europe, Southeast Asia and Japan were included. The genus Scirtes is shown to be paraphyletic with respect to the genera Ora and Exochomoscirtes. Australian Scirtes were shown to belong to four species groups: Scirtes elegans group (Yoshitomi 2009); S. helmsi group (Watts 2004); S. japonicus group (Nyholm 2002); and S. haemisphaericus group (Yoshitomi 2005). The prehensor and bursal sclerite of 15 species are illustrated as well as habitus illustrations of S. zwicki sp. nov. and S. albamaculatus Watts. Three new species from Australia are described: Scirtes lynnae, S. zwicki and S. serratus spp. nov. Scirtes nehouensis Ruta & Yoshitomi 2010 is synonymised with S. emmaae Watts 2004. Scirtes pygmaeus Watts, 2004 is synonymised with S. pinjarraensis Watts, 2006. Scirtes rutai nom. nov. is proposed as a replacement name for S. beccus Ruta, Kiałka & Yoshitomi, 2014 from Sabah as it is preoccupied by S. beccus Watts, 2004 from Australia.

This paper represents a revision of the tribe Linnaemyini in Australia but also includes the description oftwo new species of Chaetophthalmus Brauer & Bergenstamm from Papua New Guinea, being the first species of this genus to be described from outside Australia. Apalpus Malloch is regarded as a synonym of Chaetophthalmus and a key is provided to separate Chaetophthalmus from Linnaemya Robineau- Desvoidy. Keys are also provided to species of Chaetophthalmus (21 species) and Linnaemya (five species). Three new synonymies are proposed in Chaetophthalmus: C. biseriatus Malloch = C. dorsalis (Malloch); C, nudistylum (Macquart) = C. bicolor (Macquart); and C, pallipes (Curran) = C. bicolor (Macquart). Eleven new species are described in Chaetophthalmus: alienus; collessi; flavocaudus; flavopilosus; formosioides; fullerae; innotatus; longimentum; occlusus; setosus; tonnoiri. Three new species are described in Linnaemya: metocha; sarcophagoides; setulosa; L. vulpinoides (Baranov) is recorded from Australia for the first time. Descriptions of the first-instar larva of some species of both Chaetopthalmus and Linnaemya are provided.
