Abstract Stable upland habitats in arid zone biomes are often characterised by locally endemic lineages. Explanations for this pattern include habitat or substrate specialisation (ecological specialisation) intensifying aridity driving retreat into climatically buffered (climatic refugia). Here we present an analysis of these alternative models using genetic, morphological and climate data Diplodactylus galeatus , a gecko from central Australia that occurs series isolated populations associated with dissected tablelands mountain ranges. Analyses mtDNA SNP support four distinct lineages, dating analyses suggest divergence through the Pliocene. Morphological show slight differences across Investigation niche shows two lineages restricted to areas more than intervening uninhabited region. These rocky substrates, potentially subsequent paleo-erosion after Pliocene wet pulse, was key driver clade. Based on their deep genetic divergence, morphology pattern, recognise as new species.

We used a combination of nuclear and mitochondrial genetic data, body measurements colouration, male advertisement calls to analyse the systematic implications variation in whirring treefrog Litoria revelata complex, which occurs three allopatric populations—north-eastern New South Wales/south-eastern Queensland, mid-eastern northern Queensland. The populations each form divergent lineages for both (single nucleotide polymorphisms; SNP) datasets are diagnosable also on basis morphology calls. In combination, we use these lines data recognise species: L. north-eastern eungellensis sp. nov. resurrected corbeni provide preliminary conservation assessment species, with latter two species being localised very small upland areas warranting listing attention.

We describe a new species of fossorial skink, Lerista karichigara sp. nov., from the Gulf Plains Bioregion northern Queensland, Australia. The lacks forelimbs, has hindlimbs with two toes, and is characterised by colour-pattern fine, dark longitudinal lines. Although field guides keys available at time publication would identify this as L. wilkinsi, it differs that allopatric in several respects. Notably, nov. only supraciliaries do not contact each other (versus four, first three continuous row), snout shape sharper profile. Mitochondrial DNA sequence data indicate deeply divergent known possibly sister to clade nine north-eastern Australia, referred here wilkinsi clade. appears be vertebrate recognised endemic Bioregion, an expansive poorly surveyed region tropical also report geographic records for vanderduysi emmotti, which extend their distributions.
