“…We recovered a paraphyletic Leposoma because species of the L. scincoides and the L. parietale groups were not recovered as sister groups. Our results, and several previous studies based on morphological (Ruibal, ), karyotypic (Pellegrino et al., , ; Laguna et al., ) and molecular data (Pellegrino et al., ; Pyron et al., ) agree in the non‐monophyly of Leposoma . The type species of Leposoma is L. scincoides Spix, 1825, which means that the group that retains the generic name Leposoma is the taxon composed of the L. scincoides group of Ruibal (), forming the sister‐taxon of a group composed of Ecpleopus , Kaieteurosaurus , Pantepuisaurus , Colobosauroides , Dryadosaurus , Anotosaura , Marinussaurus and other species incorrectly assigned to Leposoma and Arthrosaura , for which we resurrect the name Loxopholis Cope, 1869 “1868”.…”

We infer phylogenetic relationships within Teioidea, a superfamily of Nearctic and Neotropical lizards, using nucleotide sequences. Phylogenetic analyses relied on parsimony under tree‐alignment and similarity‐alignment, with length variation (i.e. gaps) treated as evidence and as absence of evidence, and maximum‐likelihood under similarity‐alignment with gaps as absence of evidence. All analyses produced almost completely resolved trees despite 86% of missing data. Tree‐alignment produced the shortest trees, the strict consensus of which is more similar to the maximum‐likelihood tree than to any of the other parsimony trees, in terms of both number of clades shared, parsimony cost and likelihood scores. Comparisons of tree costs suggest that the pattern of indels inferred by similarity‐alignment drove parsimony analyses on similarity‐aligned sequences away from more optimal solutions. All analyses agree in a majority of clades, although they differ from each other in unique ways, suggesting that neither the criterion of optimality, alignment nor treatment of indels alone can explain all differences. Parsimony rejects the monophyly of Gymnophthalmidae due to the position of Alopoglossinae relative to Teiidae, whereas support of Gymnophthalmidae by maximum‐likelihood was low. We address various nomenclatural issues, including Gymnophthalmidae Fitzinger, 1826 being an older name than Teiidae Gray, 1827. We recognize three families in the arrangement Alopoglossidae + (Teiidae + Gymnophthalmidae). Within Gymnophthalmidae we recognize Cercosaurinae, Gymnophthalminae, Rhachisaurinae and Riolaminae in the relationship Cercosaurinae + (Rhachisaurinae + (Riolaminae + Gymnophthalminae)). Cercosaurinae is composed of three tribes—Bachiini, Cercosaurini and Ecpleopodini—and Gymnophthalminae is composed of three—Gymnophthalmini, Heterodactylini and Iphisini. Within Teiidae we retain the currently recognized three subfamilies in the arrangement: Callopistinae + (Tupinambinae + Teiinae). We also propose several genus‐level changes to restore the monophyly of taxa.

“…Although hybridization between a bisexual and a diploid unisexual has been proposed earlier for the origin of the triploid Neotropical night lizard (Leposoma percarinatum) [Pellegrino et al, 2003;Laguna et al, 2010], the current data do not permit unambiguous assignment of parental species of the unisexuals, indicating possible autotriploidy [Pellegrino et al, 2011]. Future tests of evolutionary formations are necessary for other 'difficult cases' among putative autotriploid reptiles where the assignment of diploid bisexual relatives is unclear: parthenogenetic lizards Leiolepis triploida and L. guentherpetersi [Schmitz et al, 2001;Aranyavalai et al, 2004], some Hemidactylus species (H. garnotii , H. vietnamensis , H. stejnegeri , and H. frenatus) and the chameleon Rhampholeon boulengeri (formerly Brookesia spectrum affinis ) from Congo [Hall, 1970].…”

The past decade has witnessed a tremendous increase in interest in polyploidy, which may partly be related to the development of new powerful genetic and genomic tools. These have provided numerous insights into mainly genetic and genomic consequences of polyploidy, dramatically improving our understanding of the dynamics of the polyploidization process and its importance as a mechanism in animal evolution. In contrast, several other aspects of polyploidization, such as physiology, ecology and development, have received considerably less attention. Our aim is not to make an exhaustive review of current knowledge about animal polyploidy, but rather to thoroughly elaborate on some very fundamental questions which still remain open or even neglected. In particular, we show that properties of new polyploid lineages largely depend upon the proximate way in which they arose, but the evolutionary pathways to polyploidy are often unresolved. To help researchers orientate amongst the number of pathways to polyploidy, we provide an extensive review of particular scenarios proposed in distinct animal taxa. We discuss how polyploidy relates to hybridization, particularly with respect to asexuality, and elaborate on whether clonal triploids may help to overcome the constraints of aneuploidy, thereby serving as a triploid bridge towards the establishment of new polyploid species. We further show that in most animal asexual complexes clonal lineages may become established only under one ploidy level (usually either di- or triploidy), and that it is rather rare to see the coexistence of successful clones of different ploidies. We discuss why the rate of polyploidization is higher in some taxa than in others, and what tools we have to evaluate the rate of polyploidization. Finally, we review some of the immediate physiological and developmental effects of polyploidy which are related to the genome size/cell size relation and show how studies of polyploidy may enhance the study of macroecology and developmental biology.
