“…() considered to be part of Ameiva were included in their analysis of such groups. In addition, A. provittae is a possible synonym of A. bifrontata as the characters thought to be unique to diagnose this species (such as a red snout) are present in different populations of A. bifrontata (Rivas et al., ).

“…On the other hand, the morphological variation within these groups has not been adequately studied, as the Pholidoscelis species that Harvey et al (2012) considered to be part of Ameiva were included in their analysis of such groups. In addition, A. provittae is a possible synonym of A. bifrontata as the characters thought to be unique to diagnose this species (such as a red snout) are present in different populations of A. bifrontata (Rivas et al, 2012). Therefore, it is possible that the A. bifrontata group is a monotypic group.…”

Molecular systematics of teioid lizards (Teioidea/Gymnophthalmoidea: Squamata) based on the analysis of 48 loci under tree‐alignment and similarity‐alignment

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.

“…Regional lists are small steps towards solving some of these problems, and checklists with geographic and voucher information, despite their limitations, are a good start for further detailed studies. As Rivas et al (2012) state, checklists are dynamic and should be considered as a still frame in time that has no lasting value, only showing the state of knowledge at a particular moment. Reports of new species, synonymizations and elevation of old synonyms to specific status, clarification of prior mistakes and new data about species distributions rapidly change our knowledge of biological diversity.…”

An accurate estimation of species and population geographic ranges is essential for species-focused studies and conservation and management plans. Knowledge of the geographic distributions of reptiles from Patagonian Argentina is in general limited and dispersed over manuscripts from a wide variety of topics. We completed an extensive review of reptile species of central Patagonia (Argentina) based on information from a wide variety of sources. We compiled and checked geographic distribution records from published literature and museum records, including extensive new data from the LJAMM-CNP (CENPAT-CONICET) herpetological collection. Our results show that there are 52 taxa recorded for this region and the highest species richness was seen in the families Liolaemidae and Dipsadidae with 31 and 10 species, respectively. The Patagónica was the phytogeographic province most diverse in species and Phymaturus was the genus of conservation concern most strongly associated with it. We present a detailed species list with geographical information, richness species, diversity analyses with comparisons across phytogeographical provinces, conservation status, taxonomic comments and distribution maps for all of these taxa.

“…Here, we begin to assemble one piece of that puzzle by focusing on the Neotropical snake genus Pseustes, commonly referred to as 'birdsnakes' or 'puffing snakes'. Three species are currently recognized in the genus (Rivas et al 2012): Pseustes poecilonotus G€ unther 1858; P. shropshirei Barbour and Amaral 1924;and P. sulphureus Wagler 1824; which is among the largest sized colubrid snake in the New World (P erez-Santos and Moreno 1988). Other species of Pseustes mentioned in Uetz (2013), such as P. cinnamomeus Wagler 1824 and P. sexcarinatus Wagler 1824; are considered in the synonymy of Chironius scurrulus Wagler, 1924 andC.…”

The genus Pseustes Fitzinger, 1843 is composed of three recognized species, Pseustes poecilonotus, P. shropshirei and P. sulphureus, which may be the largest sized colubrid snake in the New World. The group has a complex systematic history that has yet to be untangled using modern molecular phylogenetic approaches. The systematic position, within‐group diversity and distribution are therefore uncertain. We obtained samples of four species from multiple specimens across their distribution and analysed one nuclear and two mitochondrial genes to determine the phylogenetic placement of the genus and infer relationships among Pseustes lineages. We find strong support for the paraphyly of Pseustes with respect to the monotypic genus Spilotes, both of which are nested within a clade of at least 23 other New World Colubrinae genera. Based on our results, we formally revise the taxonomy of P. poecilonotus and P. sulphureus, resurrecting the taxon P. polylepis for populations of P. poecilonotus from South America and allocating P. sulphureus to the genus Spilotes which renders both genera monophyletic. Additionally, we identify two lineages that are putatively new and currently unrecognized species. Finally, the placement of P. sulphureus, the type species of Pseustes, in the genus Spilotes, requires the allocation of the senior synonym Phrynonax be considered for the remaining Pseustes taxa.
