Syphacia (Syphacia) brevicaudata sp. nov. is described from the desert rodents Pseudomys desertor Troughton, 1936 and P. hermannsburgensis (Waite, 1896); Syphacia (Syphacia) pseudomyos sp. nov. is described from P. hermannsburgensis from western Queensland and central Northern Territory, Australia. Syphacia (Syphacia) brevicaudata is distinguished from all other species of Syphacia by having a suite of characters including an oval, dorsally and ventrally constricted cephalic plate, no cervical alae, a relatively short tail and two pairs of post-anal papillae. Syphacia (Syphacia) pseudomyos is distinguished from all other species of Syphacia by having a suite of characters including an oval, dorsally and ventrally constricted cephalic plate, no cervical or lateral alae, one pair of post-anal papillae, a relatively short tail and large eggs. Females of a putative species were distinct due to the lack of a cephalic plate but had other characters consistent with the genus. Two other putative species of Syphacia, females only, also collected from P. hermannsburgensis and having oval dorsally and ventrally constricted cephalic plates, could be distinguished from their congeners by a combination of characters including the presence of cervical alae, Syphacia sp. 2, and a protruding vulva, Syphacia sp. 3. These new species are the first records of oxyurid nematodes from the genus Pseudomys, and from Australian arid-zone rodents.

A new assemblage containing twenty-two species of trilobites and agnostids is described from the Goyder Formation (Cambrian Series 3) in the Ross River Syncline and Gardiner Ranges of the Amadeus Basin, Northern Territory, central Australia. New trilobite taxa described include the genus, Trephina gen. nov., and four new species Adelogonus prichardi sp. nov., Hebeia stewarti sp. nov., Liostracina joyceae sp. nov., and Trephina ranfordi sp. nov. Two agnostid taxa previously known only from Antarctica, Ammagnostus antarcticus Bentley, Jago & Cooper, 2009 and Hadragnostus helixensis Jago & Cooper, 2005, are also documented. Of the two agnostid species, the latter is the most age diagnostic, previously reported from the Cambrian Series 3 (Guzhangian; late Mindyallan; Glyptagnostus stolidotus Zone) Spurs Formation in Northern Victoria Land. This age for the Goyder Formation assemblage is supported by the co-occurrence of the trilobites Biaverta reineri Öpik, 1967, Blackwelderia repanda Öpik, 1967, Henadoparia integra Öpik, 1967, Monkaspis cf. travesi (Öpik, 1967), Nomadinis pristinus Öpik, 1967, Paraacidaspis? priscilla (Öpik, 1967), and Polycyrtaspis cf. flexuosa Öpik, 1967, also known from the late Mindyallan (G. stolidotus Zone) successions of the neighbouring Georgina Basin (Northern Territory and Queensland). The generic assemblage of the Goyder Formation is also similar to those from the Guzhangian (Mindyallan) of other parts of Australia (New South Wales, South Australia, and Western Australia), in addition to East Antarctica and North and South China.

A New Species

Abstract Culex longitubus Somboon, Namgay & Harbach is described as a new species of the Mimeticus Subgroup of the subgenus Culex. The larva is most similar to the larva of Cx. tianpingensis Chen from China, but is distinguished by the length of the siphon and the anal papillae, the form of the comb scales and pecten spines, and the development of setae 7-P, 13-T, 1-X, and 4-X. The adults have wing markings and male genitalia similar to those of species of the Mimeticus Complex. Phylogenetic analysis of COI sequences revealed that the new species is closely related to Cx. murrelli Lien of the Mimulus Complex. The immature stages of the new species were found in stagnant pools and marshes at high altitudes in several districts of Bhutan.

Abstract Among Antarctic amphipods of the genus Eusirus, a highly distinctive clade of giant species is characterized by a dorsal, blade-shaped tooth on pereionites 5–7 and pleonites 1–3. This lineage, herein named ‘crested Eusirus’, includes two potential species complexes, the Eusirus perdentatus and Eusirus giganteus complexes, in addition to the more distinctive Eusirus propeperdentatus. Molecular phylogenies and statistical parsimony networks (COI, CytB and ITS2) of crested Eusirus are herein reconstructed. This study aims to formally revise species diversity within crested Eusirus by applying several species delimitation methods (Bayesian implementation of the Poisson tree processes model, general mixed Yule coalescent, multi-rate Poisson tree processes and automatic barcode gap discovery) on the resulting phylogenies. In addition, results from the DNA-based methods are benchmarked against a detailed morphological analysis of all available specimens of the E. perdentatus complex. Our results indicate that species diversity of crested Eusirus is underestimated. Overall, DNA-based methods suggest that the E. perdentatus complex is composed of three putative species and that the E. giganteus complex includes four or five putative species. The morphological analysis of available specimens from the E. perdentatus complex corroborates molecular results by identifying two differentiable species, the genuine E. perdentatus and a new species, herein described as Eusirus pontomedon sp. nov.

Three new species are described in the genus Drymopsalta Ewart, previously known only from D. crepitum Ewart and D. daemeli Distant. The three new species occur in Southern Queensland and Northern Territory. D. wallumi sp. nov. occurs along coastal S.E. Queensland, whereas D. hobsoni sp. nov. is restricted to the Bringalily State Forest, near Inglewood, southern inland Queensland. D. acrotela sp. nov. is found in the Litchfield National Park and other locations near Jabaluka, Cahills Crossing, E. Alligator River and Nourlangie, all across the northern Northern Territory. D. crepitum occurs on the Cape York Peninsular extending into the southern Gulf, while D. daemeli occurs in two localised regions in central coastal N.S.W. Each of the species inhabits heath vegetation, often spilling-over into adjacent tree foliage. The species of Drymopsalta are small and inconspicuous cicadas (<15 mm body length) with relatively high frequency songs (~15 to 22 kHz). The temporal structures of the normal calling songs follow a similar pattern in each species, consisting of the emission of short chirps (comprising 2–16 ticks). Between the chirps are emitted one (D. wallumi, D. hobsoni, D. acrotela), two (D. daemeli) or 1–9 (D. crepitum) intervening single ticks. The species can be distinguished by the timing and the number of these single ticks relative to the adjacent chirps with the notable exception of D. hobsoni and D. acrotela. The calling songs of these two allopatric species are indistinguishable, an unusual feature in Australian cicadas. Two additional song variants are described, a more unstructured chirping song without intervening single ticks observed in each of the species except D. crepitum, and periodic extended buzzing echemes emitted within the calling songs (excepting the D. wallumi song).

Two New Species

The genus Agrotera Schrank, 1802 is revised for Australia and the generic definition is refined based on the male genitalia. The genera Leucinodella Strand, 1918 stat. rev. with L. leucostola (Hampson, 1896) comb. nov., Nistra Walker, 1859 stat. rev. with N. coelatalis Walker, 1859 comb. rev., Sagariphora Meyrick, 1894 stat. rev. with S. magnificalis (Hampson, 1893) comb. nov., and Tetracona Meyrick, 1884 stat. rev. with T. amathealis (Walker, 1859) comb. rev. and T. pictalis Warren, 1896 comb. rev. are removed from synonymy with Agrotera, as they lack the synapomorphies of Agrotera. Two new species, Agrotera genuflexa sp. nov. from Northern Territory, Queensland and New South Wales, and A. longitabulata sp. nov. from Queensland, are described. The taxonomic status of the Australian species of Agrotera is discussed, and a key to all species, based on males, is provided. The adults and genitalia of the new species and some related species are figured.

Subjective Synonym

The new Ordovician palaeotaxodont family Nucularcidae and the new genus Nucularca are described. Included in Nucularca are four previously described species that have taxodont dentition: N. cingulata (Ulrich) (the type species), N. pectunculoides (Hall), N. lorrainensis (Foerste), and N. gorensis (Foerste). All four species are of Late Ordovician (Cincinnatian Katian) age and occur in eastern Canada and the northeastern USA. Ctenodonta borealis Foerste is regarded as a subjective synonym of Nucularca lorrainensis. No new species names are proposed. The Nucularcidae includes the genera Nucularca and Sthenodonta Pojeta and Gilbert-Tomlinson (1977). Sthenodonta occurs in central Australia in rocks of Middle Ordovician (Darriwilian) age. The 12 family group names previously proposed for Ordovician palaeotaxodonts having taxodont dentition are reviewed and evaluated in the Appendix.

A New Species

1. A detailed morphological study has been made of certain nematodes occurring in the basidiomycetous fungi, Entoloma rhodipolium, Pleurotus corticalus, P. ostreatus, Hygrophorus virgineus and Tricholoma cunifolium.2. From the first three of these, males and females of two species of eelworms have been obtained which are placed in the genus Iotonchium Cobb, 1920. One of these is Iotonchium fungorum (Butschli, 1878) n. comb., originally described by Butschli under the name of Tylenchus fungorum', the other is a new species which is named I. bifurcatum n. sp.3. The males of both species have peculiar lobed, dorso-ventrally flattened heads and a poorly developed mouth spear. The bursa is very large, the spicules have posterior prolongations which arc extruded through the cloaca and ventral post-anal papillae are present. A gubernaculum is absent.
