Although the south-western Australian region is recognised as a global biodiversity hotspot, there are still significant gaps in our understanding of the biodiversity of this region. We present a phylogenetic study of the heath dragons (Rankinia adelaidensis and R. parviceps) from this region, incorporating a 1612-bp section of mtDNA and two nuclear introns, Gapdh (~244 bp) and Enol (~330 bp). In addition, we present a generic-level analysis of three gene regions (mtDNA, Gapdh, BDNF), which provides clear evidence that Rankinia adelaidensis and R. parviceps are not closely related to Rankinia diemensis from eastern Australia. Instead, the heath dragons are strongly supported as forming a clade with the genus Ctenophorus. In addition, we find that there are significant levels of haplotype divergence between currently recognised subspecies of the heath dragons (R. a. adelaidensis, R. a. chapmani, R. p. parviceps, R. p. butleri). We suggest that the genetic divergences between subspecies result from geographic isolation in allopatry owing to habitat preferences, followed by drift and/or selection. On the basis of these deep divergences and consistent morphological differences between subspecies, we recommend elevating all taxa to full species, and provide a taxonomic revision of the genera Rankinia and Ctenophorus.

This paper seeks to correct the erroneous taxonomy associated with the current understanding of the Altivasum flindersi (Verco, 1914) complex based on type revision, morphological differences and geographic separation. Structurally, there are three distinct species that can be differentiated, Altivasum flindersi (Verco, 1914), A. typicum Hedley, 1916 and A. profundum sp. nov. Geographically, these species are not all sympatric, with A. typicum restricted to shallower waters, at depths around 20-180 m off the south Western Australian coast, whereas A. profundum is located at the edge of the South Western Australian continental shelf, and A. flindersi is found off the coast of the Great Australian Bight at similar depths to A. typicum. There is an overlap in distribution between A. typicum Hedley, 1916 and A. flindersi (Verco, 1914) on the western side of the Great Australian Bight where they are often associated with similar habitats.

LIKE all genera in the Goodeniaceae, the south-west of Western Australia is the centre of diversity for Lechenaultia R.Br. with 20 of 26 species in the genus endemic to the region (Keighery and Sage 1999; Morrison 1992). Many species of Lechenaultia (and Goodeniaceae) have habitat preferences for ephemerally wet sites (watercourses and lake edges), especially in the Eremaean Botanical Province (unpubl. data). Species such as L. striata (nomenclature follows Western Australian Herbarium 1998 and Orchard and Wilson 2001) and L. galactites are disturbance opportunists, showing prolific population growth after fire events (S. van Leeuwen, pers. comm.; unpubl. data). Of the remaining species scattered across central and eastern Australia, L. aphylla is the least known with only two non-flowering collections from the extreme eastern Great Victoria Desert bioregion of South Australia (including the holotype). A recent collection of the species made over 1 100 km to the west highlights the lack knowledge of the species and bioregion in general.

Based on a recent molecular phylogenetic study, the South Asian microhylid genus Uperodon (subfamily Microhylinae) currently comprises of 12 valid species that are largely restricted to India and Sri Lanka. Considering the revised generic-level status of its various members, here we review the taxonomy of all known species in this genus and clarify their nomenclatural status and geographical distribution, by integrating evidence from genetics, adult and tadpole morphology, breeding ecology, and bioacoustics. Our molecular analyses of a mitochondrial 16S rRNA gene fragment combined with external and internal morphological studies also revealed a distinct new species in the genus. This species, formally described as Uperodon rohani sp. nov., is endemic to Sri Lanka and widely distributed at lower elevations in the island. For nomenclatural stability of various previously known members, the following actions are also undertaken: (1) redescription of the poorly-defined species Ramanella anamalaiensis Rao (= Uperodon anamalaiensis) and Hylaedactylus montanus Jerdon (= Uperodon montanus); (2) neotype designation for Ramanella anamalaiensis Rao (= Uperodon anamalaiensis), Ramanella minor Rao, Ramanella mormorata Rao (= Uperodon mormorata), and Ramanella triangularis rufeventris Rao; (3) lectotype designation for Callula variegata Stoliczka (= Uperodon variegatus); and (4) synonymization of Ramanella minor Rao with Uperodon anamalaiensis.

Astraea Klotzsch (1841: 194) was considered a synonym of Croton Linnaeus (1753: 1004) by many authors (Baillon 1858, Müller 1866, Pax & Hoffmann 1931, Webster 1994, Radcliffe-Smith 2001), but based on a molecular phylogenetic study of Croton and related groups, Berry et al. (2005a) justified recognizing Astraea again as a valid genus. De-Paula et al. (2011) showed morphological differences in the flowers of these two genera, corroborating the findings of Berry et al. (2005a). Riina et al. (2014) discussed additional morphological characters separating Astraea from both Croton and its sister genus Brasiliocroton Berry & Cordeiro in Berry et al. (2005b: 357). Some species that were originally described under Croton have already been transferred to Astraea (Berry et al. 2005a, Caruzo & Cordeiro 2007, Zuloaga et al. 2007, Van Ee 2011), and Van Ee (2011) accounted for numerous names of Astraea invalidly published by Klotzsch (1841). However, there are still several species of Croton that should be transferred to Astraea. As part of an ongoing taxonomic revision of the genus Astraea, we herein propose the necessary remaining transfers. Astraea has an estimated 13 species, most of them distributed in South America, especially in Brazil. Astraea lobata (Linnaeus 1753: 1005) Klotzsch (1841: 194) is the only species occurring throughout the Neotropical region and is also found, introduced, in Africa and Yemen.
