Close examination of specimens of the Ozothamnus ledifolius species complex (O. ledifolius, O. ericifolius and O. purpurascens) collected throughout Tasmania, Australia, revealed the existence of more taxa than hitherto recognised. An integrative approach employing morphological, genotyping and environmental data of specimens resolved the complex, and showed good support for O. ledifolius and O. ericifolius as currently circumscribed, further clarifying the existence of four additional, distinct taxa: Ozothamnus purpurascens, with revised and clarified typification; O. reflexus comb. & stat. nov., a taxon to which the name O. purpurascens was previously misapplied; O. buchananii spec. nov., a novel taxon from mid–high elevations in north-eastern Tasmania; and O. floribundus spec. nov., a rare and highly localised novel taxon in lowland south-eastern Tasmania.

Ordination Analysis

The Banksia integrifolia (Proteaceae : Grevilleoideae) species complex currently comprises three varieties: var. aquilonia from northern Queensland; var. integrifolia from coastal Victoria and New South Wales; and var. compar, which is polymorphic and comprises two forms, a coastal form from southern Queensland and a montane form from north-eastern New South Wales and south-eastern Queensland. Ordination analysis of morphological characters of adults and seedlings indicates that the montane populations of var. compar comprise a separate taxon, which is phenetically closer to var. integrifolia than it is to typical var. compar. Banksia integrifolia var. aquilonia is phenetically quite distinct from the remaining taxa. The new names and combinations Banksia integrifolia subsp. monticola K.R. Thiele, B. integrifolia subsp. aquilonia (A.S. George) K.R. Thiele and B. integrifolia subsp. compar (R.Br.) K.R. Thiele are published.

Integrative taxonomic approaches are increasingly providing species-level resolution to ‘cryptic’ diversity. In the absence of an integrative taxonomic approach, formal species validation is often lacking because of inadequate morphological diagnoses. Colouration and chaetotaxy are the most commonly used characters in collembolan taxonomy but can cause confusion in species diagnoses because these characters often have large intraspecific variation. Here, we take an integrative approach to the genus Dicranocentrus in China where four species have been previously recognised, but several members of the genus have been morphologically grouped as a species complex based on having paired outer teeth on unguis and seven colour patterns. Molecular delimitations based on distance- and evolutionary models recovered four candidate lineages from three gene markers and revealed that speciation events likely occurred during the late Neogene (4–13million years ago). Comparison of intact dorsal chaetotaxy, whose homologies were erected on the basis of first instar larva, further validated these candidates as formal species: D. gaoligongensis, sp. nov., D. similis, sp. nov., D. pallidus, sp. nov. and D. varicolor, sp. nov., and increase the number of Dicranocentrus species from China to eight. Our study further highlights the importance of adequate taxonomy in linking morphological and molecular characters within integrative taxonomy.

Abstract Piresia, a small genus of herbaceous bamboos, has a geographical disjunction between the Caribbean and northern/western South America and the north-eastern Atlantic Forest in Brazil. Piresia leptophylla is reported from western Amazonia (WA) and the north-eastern Atlantic Forest (NAF), but its occurrence in western Amazonia is questionable. Using an integrative approach, we combined traditional morphological analysis, anatomy and niche modelling. The results revealed few macromorphological differences between WA and NAF specimens (only plant height, leaf length, lodicule dimensions, shape and position), contrasting with consistent differences in leaf anatomy (macrohairs and cruciform silica bodies in the costal zone of the adaxial/abaxial leaf surfaces, crenate silica bodies on the abaxial leaf surface, lack of panicoid hairs on the abaxial leaf surface, bicellular microhairs and lobed papillae over the abaxial leaf surface, and sparse but elongated fusoid cells in the mesophyll of WA specimens) and in niche patterns. The anatomical/micromorphological characters suggest environmental adaptations to the Amazonian and ‘restinga’ forests, respectively. We therefore propose the segregation of the WA populations into a new species, Piresia tenella sp. nov. We provide a formal description, photographs, a line illustration, a distribution map and discussion of the conservation status for the new species.

The Noctuidae fauna of Kazakhstan is species-rich and still poorly studied. During a lepidopterological expedition to Almaty Region in the south-eastern part of Kazakhstan, a single female of an unknown Noctuidae species belonging to the subfamily Oncocnemidinae was collected by the senior author of the present paper. The species resembles externally members of the genus Lophoterges Hampson, 1906, especially Lophoterges fatua (Püngeler, 1904), but examination of its genitalia structure revealed that the species is not only undescribed and remarkably different from all known Lophoterges species, but belongs to another genus, Epimecia Guenée, 1839. Up to date, the genus Epimecia was considered as monotypic (Ronkay & Ronkay 1995; Kononenko 2016) and included only Epimecia ustula (Freyer, 1835), which is widely but disjunctively distributed from south-eastern France through the southern Alps, the Balkans, Turkey, Ukraine, southern European part of Russia and western Kazakhstan to southern Ural, north-eastern Kazakhstan and southern Siberia (Ronkay & Ronkay 1995; Kononenko 2016; Titov et al. 2017). The second, peculiar Kazakhstan species of the genus is described below as new.

In south-eastern Australia banding of M. schreibersii has been concentrated in four areas: north-eastern New South Wales, south-eastern New South Wales, south-eastern Victoria, and south-western Victoria and south-eastern South Australia. The present paper analyses 2083 reported movements. Only 17 of these are from one of the four areas to another with the longest movement being 810 miles. Biologically and geographically separate populations of M. schreibersii are recognized in both north-eastern and south-eastern New South Wales. Each population has its basis in dependence upon a specific nursery site which is used annually by nearly all adult females in that population. Boundaries of population ranges in New South Wales are considered to be prominent features of physiography (i.e. divides). Bats move between population ranges less often than they move within population ranges. This cannot be explained solely in terms of the distances separating roosts. Available movement records from Victoria and South Australia are consistent with the pattern described for New South Wales. Two biologically recognizable populations (i.e, different birth periods) occur in south-western Victoria and south-eastern South Australia but these may have overlapping ranges. Only one nursery colony of M. schreibersii is known from south-eastern Victoria. On present evidence it remains possible that the apparent integrity of the population associated with this nursery is merely a consequence of distance from other areas of banding activity. Detailed analyses of movements in bats may provide direct evidence as to the kinds of cues by which a given species navigates. Thus the physiographic basis described for population ranges in New South Wales is consistent with the view that M. schreibersii may orientate to waterways or divides or both. The probability that there are area differences in the subtlety or nature of navigational cues is implied by the different physiographic circumstances of south-western Victoria and south-eastern South Australia. It is suggested that knowledge of population range boundaries may aid planning of meaningful homing experiments.

Geographically Isolated

Based on a combination of morphological and genetic data, geographically isolated populations of Pygopus from northeastern Queensland, formerly referred to Pygopus lepidopodus (Lacépède), are herein described as a new species. Pygopus robertsi sp. nov. can be diagnosed from its congeners by a suite of scalation characters, including fewer keeled dorsal scales, presence of a single continuous row of supracilaries and a lower number of midbody scale rows. It is also deeply divergent genetically from samples of Pygopus lepidopodus from southern Australia. The known distribution of Pygopus robertsi sp. nov. is similar to that of a number of taxa centred upon relatively dry ecotonal habitats at the western edge of the rainforest blocks of north-eastern Queensland. Additional samples and systematic work will be required to examine the evolutionary divergence of apparently isolated populations of the new species, and the significance of considerable genetic and morphological diversity within remaining populations of Pygopus lepidopodus from south-eastern and southern Australia.
