Myrmicine Ants

Monomorium Mayr is a speciose, cosmopolitan genus of myrmicine ants that has had a challenging systematic history, comprising numerous lineages whose relationships are problematic. This study employed an extensive sampling of mostly Australian taxa, along with exemplars of other genera of Solenopsidini, to examine relationships among the continent’s Monomorium fauna. Sequences from elongation factor 1α F2, wingless and cytochrome oxidase subunit 1 (COI) were analysed using Bayesian and maximum likelihood methods. The resultant phylogeny resolved Australian Monomorium into two major clades separated by exemplars from other genera; one comprised predominantly species with 11-segmented antennae (corresponding to Monomorium s. str. in a recent study of Myrmicinae) along with three Paleotropical species. The second clade included Australian species with 12-segmented antennae, two New Zealand species and two from New Caledonia. Two Australian cryptobiotic species were resolved as sister to Clade 2. COI analysis indicated that some species (M. fieldi Forel, M. leave Mayr and M. leae Forel) possibly represent cryptic species complexes. The New Zealand M. antipodum Forel was recovered as a valid species, and is closely related to an eastern Australian population. We resurrect the genus Chelaner Emery for species in the second clade (with 12-segmented antennae) and outline morphological characters to separate Chelaner from Monomorium s. str. Fifty-three species of Chelaner are treated as either stat. nov. or stat. rev.

Crypturgus subcribrosus Eggers is removed from synonymy under C. cinereus (Herbst) and reinstated as a valid species based on evidence from DNA sequence data and morphological features. Phylogenetic analyses of Elongation Factor 1α and Cytochrome Oxidase I sequences in conjunction with morphological characters revealed a sister relationship between C. subcribrosus and two Nearctic species of Crypturgus, with C. cinereus unrelated to any of these taxa. Type material of C. cinereus has been located and lectotype with paralectotypes are designated. Amended diagnoses that include DNA barcodes are presented for C. subcribrosus and C. cinereus together with an identification key to the Fennoscandian species of Crypturgus.

AbstractThe lithobiomorph centipede Henicops is widely distributed in Australia and New Zealand, with five described species, as well as two species in New Caledonia and Lord Howe Island. Parsimony, maximum likelihood and Bayesian analyses of ca. 800 aligned bases of sequence data from 16S rRNA and 28S rRNA were conducted on a dataset including multiple individuals of Henicops species from populations sampled from different parts of species' geographic ranges, together with the allied henicopines Lamyctes and Easonobius. Morphological characters are included in parsimony analyses. Molecular and combined datasets unite species from eastern Australia and New Zealand to the exclusion of species from Western Australia, New Caledonia and Lord Howe Island. The molecular data favour these two geographic groupings as clades, whereas inclusion of morphology resolves New Caledonia, Lord Howe Island, southwest Western Australia and Queensland as successive sisters to southeastern Australia and New Zealand. The basal position of the Lord Howe Island species in the phylogeny favours a diversification of Australasian Henicops since the late Miocene unless the Lord Howe species originated in a biota that pre-dates the island. The molecular and combined data resolve the widespread morphospecies H. maculatus as paraphyletic, with its populations contributing to the geographic groupings New South Wales + New Zealand and Tasmania + Victoria.

This study examines the phylogeny, taxonomy, distribution and biology of the gasteruptiid subfamily Hyptiogastrinae and, at the same time, presents an overview of the family. Following a cladistic analysis of 35 discrete morphological characters, two monophyletic genera are recognised, Hyptiogaster Kieffer and Pseudofoenus s. l. Kieffer. As a consequence, the genera Aulacofoenus Kieffer, Crassifoenus Crosskey, and Eufoenus Szépligeti are synonymised with Pseudofoenus. A total of 88 species are recognised for the subfamily, 10 species of Hyptiogaster, which are restricted to mainland Australia, and 78 species of Pseudofoenus, 40 of which are described as new. Pseudofoenus has a restricted Gondwanan distribution and is found in Australia including Tasmania (65 spp.), New Guinea and New Britain (5 spp.), the south-west Pacific (New Caledonia, New Hebrides and Fiji – 2 spp.), New Zealand (4 spp.) and South America (2 spp.). No new species have been recorded from either New Zealand or South America. For Pseudofoenus, information on the distribution of each species, their biology (if known) and an identification key are presented.Following a taxonomic revision, the following new species are described: P. baileyi, sp. nov., P. baitetaensis, sp. nov., P. beverlyae, sp. nov., P. caperatus, sp. nov., P. cardaleae, sp. nov., P. carrabinensis, sp. nov., P. claireae, sp. nov., P. collessi, sp. nov., P. coorowensis, sp. nov., P. crosskeyi, sp. nov., P. douglasorum, sp. nov., P. eliseae, sp. nov., P. ericae, sp. nov., P. eustonensis, sp. nov., P. feckneri, sp. nov., P. gressitti, sp. nov., P. gullanae, sp. nov., P. hackeri, sp. nov., P. imbricatus, sp. nov., P. iqbali, sp. nov., P. kadowi, sp. nov., P. karimuiensis, sp. nov., P. kelleri, sp. nov., P. leinsterensis, sp. nov., P. macdonaldi, sp. nov., P. malkini, sp. nov., P. marshalli, sp. nov., P. masneri, sp. nov., P. mitchellae, sp. nov., P. morganensis, sp. nov., P. nalbarraensis, sp. nov., P. pumilis, sp. nov., P. schmidti, sp. nov., P. stevensi, sp. nov., P. tasmaniensis, sp. nov., P. taylori, sp. nov., P. umboiensis, sp. nov., P. walkeri, sp. nov. and P. zborowskii, sp. nov. The synonymy of Aulacofoenus, Crassifoenus and Eufoenus with Pseudofoenus result in the following new combinations: from Aulacofoenus: P. bungeyi (Jennings & Austin), comb. nov., P. deletangi (Schletterer), comb. nov., P. fallax (Schletterer), comb. nov., P. fletcheri (Jennings & Austin), comb. nov., P. goonooensis (Jennings & Austin), comb. nov., P. infumatus (Schletterer), comb. nov., P. kurmondi (Jennings & Austin), comb. nov., P. loxleyi (Jennings & Austin), comb. nov., P. marionae (Jennings & Austin), comb. nov., P. perenjorii (Jennings & Austin), comb. nov., P. swani (Jennings & Austin), comb. nov., P. thoracicus (Guérin Menéville), comb. nov., P. whiani (Jennings & Austin), comb. nov. and P. wubinensis (Jennings & Austin), comb. nov.; from Crassifoenus: P. houstoni (Jennings & Austin), comb. nov., P. grossitarsis (Kieffer), comb. nov and P. macronyx (Schletterer), comb. nov.; and from Eufoenus: P. antennalis (Schletterer), comb. nov., P. australis (Westwood), comb. nov., P. crassitarsis (Kieffer), comb. nov., P. darwini (Westwood), comb. nov., P. extraneus (Turner), comb. nov., P. ferrugineus (Crosskey), comb. nov., P. floricolus (Turner), comb. nov., P. inaequalis (Turner), comb. nov., P. melanopleurus (Crosskey), comb. nov., P. minimus (Turner), comb. nov., P. nitidiusculus (Turner), comb. nov., P. patellatus (Westwood), comb. nov., P. pilosus (Kieffer), comb. nov., P. reticulatus (Crosskey), comb. nov., P. rieki (Crosskey), comb. nov., P. ritae (Cheesman), comb. nov. and P. spinitarsis (Westwood), comb. nov.

A New Species

Abstract Frullania is a large and taxonomically complex genus. Here a new Frullania, F. toropuku von Konrat, de Lange & Larraín, sp. nov. is described from New Zealand. Frullania toropuku is placed in F. subg. Microfrullania. The new species is readily recognised by a combination of morphological characters associated with branching, the perianth, sexuality, and sporophyte, which distinguish it from all other New Zealand and regional species of Frullania. However, morphologically F. toropuku most closely resembles the widespread F. rostrata, which might well be regarded as a Southern Hemisphere equivalent of the Holarctic F. tamarisci species-complex in terms of its cryptic diversity. A combination of morphological characters associated with branching, the perianth, sexuality, and sporophyte distinguish F. toropuku from all other New Zealand and regional species of Frullania. A comparison is made between F. toropuku and morphologically allied species of botanical regions outside the New Zealand region and an artificial key is provided. In a prior investigation, maximum parsimony and maximum likelihood analyses of nuclear ribosomal ITS2 and plastidic trnL-trnF sequences from purported related species confirms its independent taxonomic status and corroborates its placement within F. subg. Microfrullania. The ongoing studies of Frullania species-complexes reveal the urgent need for more species-level phylogenies with extensive population sampling to approximate the actual diversity of Frullania, and to elucidate speciation processes and distribution range formation.

The genus Profundiconus Kuroda, 1956 is reviewed. The morphological characters of the shell, radular tooth and internal anatomy of species in Profundiconus are discussed. In particular, we studied Profundiconus material collected by dredging in deep water during different scientific campaigns carried out in the Solomon Islands, Madagascar, Papua New Guinea and New Caledonia. We reconstructed a phylogeny of 55 individuals based on partial mitochondrial cox1 gene sequences. The phylogeny shows several clades containing individuals that do not match any of the known species of Profundiconus based on their shell and radular morphologies, and are introduced here as five new species: Profundiconus maribelae sp. nov. from the Solomon Islands; P. virginiae sp. nov. from Chesterfield Plateau (New Caledonia); P. barazeri sp. nov. from Chesterfield Plateau and the Grand Passage area (New Caledonia); P. puillandrei sp. nov. from Norfolk Ridge (New Caledonia), Kermadec Ridge (New Zealand) and possibly Balut Island (Philippines); and P. neocaledonicus sp. nov. from New Caledonia. Furthermore, Profundiconus teramachii forma neotorquatus (da Motta, 1984) is raised to specific status as P. neotorquatus (da Motta, 1984).

Species Richness And Abundance

AbstractAmong the few crustacean taxa that managed to inhabit terrestrial environments, Oniscidea includes the most successful colonizers in terms of species richness and abundance. However, neither morphological traits nor molecular markers have definitively resolved phylogenetic relationships among major Oniscidea clades or established the monophyly of the taxon. Herein, we employed the highly conserved, nuclear protein-coding genes Sodium-Potassium Pump (NAK) and Phosphoenolpyruvate Carboxykinase (PEPCK), along with the traditionally used 18 s and 28 s ribosomal RNA genes, in an attempt to clarify these questions. Our dataset included sequences representing all major Oniscidea clades and closely related aquatic taxa, as suggested by previous studies. We applied Bayesian Inference and Maximum Likelihood methods and produced a robust and fully resolved phylogenetic tree that offers strong evidence against the monophyly of Oniscidea. The amphibious genus Ligia appears to be more closely related to representatives of marine suborders, while the phylogenetic pattern of the remaining Oniscidea implies a complex history of the transition from the marine environment to land. With the exception of the basal clade, all other established major clades have been recovered as monophyletic, even though relationships within these clades call for a revised interpretation of morphological characters used in terrestrial isopod taxonomy.

A section-based taxonomy of Cortinarius, covering large parts of the temperate North and South Hemispheres, is presented. Thirty-seven previously described sections are reviewed, while another forty-two sections are proposed as new or as new combinations. Twenty additional clades are recovered but not formally described. Furthermore, six new or combined species names are introduced, and one species is neotypified. The structure is supported by morphological characters and molecular evidence, based on two (nrITS and nrLSU) and four (nrITS, nrLSU, rpb1 and rpb2) loci datasets and analysed by Maximum Likelihood methods (PhyML, RAxML). Altogether 789 Cortinarius samples were included in the study.

Abstract Paepalanthus is a diverse monocot genus with remarkable diversity distributed in the Neotropical highlands of South America. The genus comprises 410 species arranged in subgenera, sections, subsections and series. Added to this complex classification, Paepalanthus shows considerable morphological heterogeneity and includes three other genera in it, Actinocephalus (Körn.) Sano, Lachnocaulon Kunth and Tonina Aubl. A broadly sampled phylogenetic inference for the genus is still missing, precluding a better understanding of its delimitation and further studies in the group. Here we present the most comprehensive phylogenetic study for Paepalanthus to date, as well as morphological survey of characters that delimit the main lineages found. We assembled a morphologically and geographically representative sampling of Paepalanthus and associated genera comprising 356 accessions in a combined dataset of plastid (trnL-F, psbA-trnH) and nuclear (ITS, ETS) regions. Bayesian inference and maximum likelihood methods were used for phylogenetic reconstruction. We found that Paepalanthus and 16 of its 28 infrageneric categories are not monophyletic, as well as the closely related genus Actinocephalus. Thirty-six well-supported clades are recognized. Morphological characters show high levels of homoplasy, and concepts traditionally used in the classification of Paepalanthus were found to be inconsistent. We confirmed that Paepalanthus as currently circumscribed is not monophyletic and revealed several new relationships in Eriocaulaceae. To make Paepalanthus monophyletic, the genus must be re-circumscribed. These results also provide a foundation for future investigations of the diversification and evolution of flora of the Neotropical highlands of South America.

AbstractFive new Helicopha species are described from New Caledonia: H. paniensis sp.n., H. amieuensis sp.n., H. einap sp.n., H. ramea sp.n. and H. dognyensis sp.n. The new species are all endemic to New Caledonia and described herein. Distributional data is included on maps for all eight New Caledonian Helicopha species. A key to the males of New Caledonian Helicophidae is presented. Phylogenetic analyses performed on morphological characters of the males of Helicophidae species show that the New Caledonia Helicopha are monophyletic, but the relationship between the Australian and New Caledonian Helicopha species is at present not fully understood. Analyzing with equally weighted characters leaves the Australian Helicopha as the sistergroup to the New Caledonian Helicopha. When characters are weighted using implied weights and concavity constant of 2, the New Zealand Zelolessica split the New Caledonian and Australian Helicopha, leaving Helicopha paraphyletic. The monotypic New Caledonian genus Briama is closely related to Helicopha in all results.
