Revision of the genus Cyrtodactylus Gray, 1827
(Squamata: Gekkonidae) in Australia

The gekkonid lizard genus Cyrtodactylus in Australia is revised based on a combination of morphology and mitochondrial (ND2) sequence data. Previous hypotheses that the Australian populations are assignable to a New Guinea species, C. louisiadensis, or to a Cyrtodactylus louisiadensis species group defined on shared colour pattern and enlarged subcaudal scales, are rejected. Evidence is provided for the existence of five endemic species in Australia, allopatrically distributed. Cyrtodactylus tuberculatus (Lucas & Frost) is formally resurrected for Australian populations in the Cooktown area, from Mt Leswell north to Stanley Island. Four new species are described: C. mcdonaldi sp. nov. in the south, from the Chillagoe area north to Parrot Creek Falls, C. hoskini sp. nov. from the Iron Range area, C. adorus sp. nov. from the Pascoe River drainage, and C. pronarus sp. nov. from the McIlwraith Range. Concordant genetic and morphological evidence enable the hypothesis that C. adorus and C. pronarus represent a species pair distinct from the sublineage represented by C. tuberculatus, C. mcdonaldi and C. hoskini.

Sorting out Lalos: description of new species and additional taxonomic data on megophryid frogs from northern Indochina (genus Leptolalax, Megophryidae, Anura)


Frogs in the subgenus Lalos of the genus Leptolalax (Megophryidae) are highly diversified in continental Asia and consist of about 17 nominal species. These frogs are small, inconspicuous, and of high superficial morphological similarity. We here formulate a hypothesis of phylogenetic relationships and assess the amount of genetic variation among genealogical lineages on the basis of 536bp of mitochondrial 16S rDNA sequences. Combining molecular data with a study of morphology, morphometric divergence and geographical proximity, we tested hypotheses of species identity. We (1) used characterbased and morphometric analyses to assign the onymophoronts (type specimens) of species in Lalos available to us to respectively one of the main clades, in order to propose the best potential correct taxonomic and nomenclatural allocation for the individuals included in the molecular study, and (2) tried to also assign the historical museum specimens to these molecular taxonomic units and to reclassify them whenever necessary.
We also used the molecular data to match tadpoles with adults and provide tadpole descriptions for species the larvae of which were previously unknown. Specimens, that could neither be allocated to a molecularly characterised species (on the basis
of their DNA “barcode”) nor to a morphologically defined species named on the basis of a type specimen, are described here as new species. Based on this integrative set of data and analyses we describe two new species, Leptolalax eos n. sp. and Leptolalax
nyx n. sp., we resurrect Leptolalax minimus, and reassess the distribution of the species studied. We propose changes in the Red List status of L. pelodytoides and L. ventripunctatus and suggest a conservation status for the new species described herein.
