“…In a taxonomic monograph of the Pygopodidae, Kluge (1974) recognized nine species of Aprasia . The known species richness of this genus has since grown to 14 species after an additional five species were discovered in Western Australia ( Storr, 1978 ; Smith & Henry, 1999 ; Maryan, Bush & Adams, 2013 ; Maryan, How & Adams, 2013 ; Maryan, Adams & Aplin, 2015 ). There have been several attempts to place these species in a phylogenetic tree though none of the studies have placed all of them into a single tree.…”

“…Aplin. However, because Maryan, Bush & Adams (2013) had subsumed A. fusca into A. rostrata , the group now contains eight, not nine, species ( Maryan, Adams & Aplin, 2015 ). Nonetheless, this species group contains eight of the fourteen recognized species in Aprasia .…”

“…First, several studies were concerned with relationships among genera and majority of the species known at the time ( Kluge, 1976 ; Jennings, Pianka & Donnellan, 2003 ; Brennan, Bauer & Jackman, 2016 ; Brennan & Oliver, 2017 ; Skipwith, Bi & Oliver, 2019 ). Second, other studies attempted to resolve relationships within putative species groups and to describe new species ( James, Donnellan & Hutchinson, 2001 ; Maryan, Aplin & Adams, 2007 ; Oliver, Couper & Amey, 2010 ; Maryan, Bush & Adams, 2013 ; Maryan, How & Adams, 2013 ; Maryan, Adams & Aplin, 2015 ; Maryan et al, 2015 ; Kealley et al, 2020 ). “Species groups” are subjectively defined and presumably monophyletic groups (usually of closely-related congeneric species) that had been defined in previous taxonomic and phylogenetic studies on the basis of morphological and/or molecular evidence.…”

Here, I review phylogenetic studies of the lizard family Pygopodidae, a group of 47 extant species that diversified in Australia and New Guinea. The goal of this study was to examine published phylogenetic and phylogenomic hypotheses on pygopodids to identify the strengths and weaknesses in our understanding of their phylogeny. Many parts of the pygopodid family tree are well established by multiple independent tree inferences including: (1) all multispecies genera (i.e., Aprasia, Delma, Lialis, Pletholax, and Pygopus) are monophyletic groups; (2) the root of the pygopodid tree is located along the branch leading to the Delma clade, thus showing that Delma is the sister group to all other pygopodid genera; (3) the Aprasia repens group, Delma tincta group, and several other groups of closely related species are demonstrated to be monophyletic entities; and (4) the monotypic Paradelma orientalis is the sister lineage to the Pygopus clade. Based on accumulated phylogenetic evidence, two taxonomic recommendations are given: Paradelma merits generic status rather than being subsumed into Pygopus as some earlier studies had suggested, and the monotypic Aclys concinna should be recognized as a member of Delma (following current practice) until future studies clarify its placement inside or outside the Delma clade. One chronic problem with phylogenetic studies of pygopodids, which has limited the explanatory power of many tree hypotheses, concerns the undersampling of known species. Although the continual addition of newly described species, especially over the past two decades, has been a major reason for these taxon sampling gaps, deficits in species sampling for ingroups and/or outgroups in several studies of pygopodid species complexes has confounded the testing of some ingroup monophyly hypotheses. Ancient hybridization between non-sister lineages may also be confounding attempts to recover the relationships among pygopodids using molecular data. Indeed, such a phenomenon can explain at least five cases of mito-nuclear discordance and conflicts among trees based on nuclear DNA datasets. Another problem has been the lack of consensus on the relationships among most pygopodid genera, an issue that may stem from rapid diversification of these lineages early in the group’s history. Despite current weaknesses in our understanding of pygopodid phylogeny, enough evidence exists to clarify many major and minor structural parts of their family tree. Accordingly, a composite tree for the Pygopodidae was able to be synthesized. This novel tree hypothesis contains all recognized pygopodid species and reveals that about half of the clades are corroborated by multiple independent tree hypotheses, while the remaining clades have less empirical support.

Agradeço primeiro e principalmente à minha orientadora, Dra. Tiana Kohlsdorf, pelo constante incentivo, encorajador apoio e pelas conversas empolgantes. Sou grato pela oportunidade e pelo privilégio de poder crescer, profissional e pessoalmente, diante de mentora, profissional e pessoa a quem tanto admiro. Pelo constante aprendizado, dentro e fora do laboratório, e pelos ensinamentos que vão muito além da ciência e dos avanços detalhados nestas páginas, e que se iniciaram em sala de aula, quando comecei a entender o quão fascinante estudar Evolução pode ser. Muito obrigado! Ao Dr. Anthony Herrel, pela oportunidade e privilégio único de poder compartilhar de sua empolgação e excelência. Durante minha graduação, quando tive contato com uma de suas inúmeras publicações, Anthony contribuiu indiretamente pelo meu ávido interesse por biologia evolutiva. Durante o mestrado, foi essencial para que eu reavivasse e confirmasse minha paixão por esta área, me recebendo em seu laboratório e me proporcionando uma experiência enriquecedora, formadora e inesquecível. Merci beaucoup! Aos curadores, técnicos e profissionais envolvidos com as coleções biológicas e museus do Brasil e do mundo, diante da recente tragédia ocorrida em Setembro de 2018, no Museu Nacional do Rio de Janeiro. Eu espero que trabalhos como este ressaltem o papel imprescindível destas instituições, e dos responsáveis por sua manutenção e funcionamento, para o futuro da ciência. Agradeço à Dra. Aline Benetti, Dr. André Braga, Chico, e ao curador, Prof. Dr. Hussam Zaher, por me receberem de braços abertos em minhas várias visitas à Coleção Herpetológica do Museu de Zoologia da Universidade de São Paulo. Ao Dr. Nicolas Vidal e ao Yves Boussicaud, e toda a equipe do laboratório de herpetologia associado à Coleção do Museu Nacional de História Natural de Paris, por me receberem em seu espaço e por me auxiliarem ao longo de vários meses em minha busca por espécies notáveis de lagartos do mundo todo. Ao Dr. Patrick Campbell, do Museu de História Natural de Londres, e ao Dr. Frank Tillack, do Museu de História Natural de Berlim, por me receberem e se embrenharem comigo pelos extensos corredores destas prestigiosas instituições. Aos curadores e gerentes de coleções que concederam empréstimo de alguns dos espécimes utilizadas neste estudo: Dr. Guarino Colli (Coleção Herpetológica da UnB), Dr. Richard
