“…One of us (LM) observed morphological characters of species and took all measurements using a caliper with a precision of 0.1 mm. We referred to the literature for patterns of scalation and coloration of the following taxa: Cercosaura anordosquama, C. ocellata, C. bassleri and C. olivacea [13]; Cercosaura argulus, C. eigenmanni, and C. oshaughnessyi [47]; C. hypnoides [17]; C. quadrilineata, C. schreibersii, and C. phelpsorum [18]; C. doanae [16]; C. manicata [30]; C. nigroventris [48]; C. parkeri [49]; and C. steyeri [50]. We also examined specimens of Cercosaura deposited in the CORBIDI, MUBI, and MUSA collections (Appendix A).…”

“…In particular, researchers have discovered many species of lizards of the family Gymnophthalmidae in poorly explored regions [4][5][6][7][8][9]. Recent phylogenetic inferences using molecular sequences have uncovered the phylogenetic relationships of many gymnophthalmid taxa [10][11][12][13]. However, there are still species whose phylogenetic position remains unclear, such as some populations currently assigned to the genus Cercosaura Wagler, 1830 and Pholidobolus anomalus Müller, 1923.…”

A New Species of Andean Gymnophthalmid Lizard (Squamata: Gymnophthalmidae) from the Peruvian Andes, and Resolution of Some Taxonomic Problems

The family Gymnophthalmidae is one of the most speciose lineages of lizards in the Neotropical region. Despite recent phylogenetic studies, the species diversity of this family is unknown and thus, its phylogenetic relationships remain unclear and its taxonomy unstable. We analyzed four mitochondrial (12S, 16S, Cytb, ND4) and one nuclear (c-mos) DNA sequences of Pholidobolus anomalus, Cercosaura manicata boliviana and Cercosaura sp., using the maximum likelihood method to give insights into the phylogenetic relationships of these taxa within Cercosaurinae. Our results suggest that Pholidolus anomalus is nested within the clade of Cercosaura spp., that material we collected near Oxapampa belongs to a new species of Cercosaura, and that lizards identified as Cercosaura manicata boliviana belong to a separate lineage, possibly a new genus. We assign Pholidobolus anomalus to Cercosaura, redescribe the species, and designate a neotype to replace the lost holotype. In addition, we describe the new species of Cercosaura, and comment about the taxonomic status of “Cercosaura manicata boliviana”incertae sedis.

“…We adopted Borges -Martins' (1998) classification of the Ophiodes species, given that this is the most complete review of the group, although data have not yet been published. Additionally, we also considered nomenclatural changes posterior to the publication of Costa & Bérnils (2018), such as the synonymizations of Cercosaura ocellata ocellata with C. olivacea Gray, 1845 (Sturaro et al, 2018), Sibynomorphus with Dipsas (Arteaga et al, 2018), and Uromacerina ricardinii with Cercophis auratus (Hoogmoed et al, 2019) and the transfer of Mastigodryas bifossatus to the genus Palusophis (Montingelli et al, 2019).…”

“…A number of subsequent studies have increased the knowledge on reptile composition of RJ by inventorying areas in the state (e.g., Citeli et al, 2016;Rocha et al, 2018;Martins et al, 2019) extending the geographic distribution of some species (e.g., Silveira, 2008;Goyannes-Araújo et al, 2009;Hamdan et al, 2015), describing new taxa (e.g., Fernandes et al, 2010;Prates et al, 2020), and providing new records of non-indigenous species (e.g., Siciliano et al, 2014;Oliveira et al, 2018). The recent advances, along with a number of additional taxonomic adjustments through the years (e.g., Sturaro et al, 2018;Hoogmoed et al, 2019), made the species list of RJ become outdated. Therefore, there was a need to update the state's species list in order to facilitate conservation and management strategies and, to reinforce the need for studies on the current species distribution.…”

Non-Avian Reptiles of the state of Rio de Janeiro, Brazil: status of knowledge and commented list

et al. 2020

We assessed the current knowledge on non-avian reptile species composition in the state of Rio de Janeiro (RJ), southeastern Brazil. We used published data in indexed journals and verified voucher specimens housed in two herpetological collections of the Museu Nacional (UFRJ), and the Laboratory of Reptiles (ZUFRJ). We also confirmed vouchers from Instituto Vital Brazil (IVB) and from the Museum of Comparative Zoology (MCZ). We compiled a list containing 149 species of reptiles, distributed among Testudines (N = 15), Crocodylia (N = 1) and Squamata (N = 133; six amphisbaenians, 38 lizards and 89 snakes). Our results add 20 species to the previous list known for the state. Four species recorded are endemic to the state of Rio de Janeiro (Anolis neglectus, Glaucomastix littoralis, Leposternon scutigerum, and Liolaemus lutzae). We identified that 21 reptile species recorded in RJ state (nearly 15% of the total) are included in some threat category either in the IUCN, Brazilian (ICMBio) or state lists of endangered species. We also report that seven of the reptiles recorded are non-indigenous to the state: Cnemidophorus aff. lemniscatus (= Cnemidophorus cryptus), Anolis sagrei, Trachemys scripta, Trachemys dorbigni, Hemidactylus mabouia, Crotalus durissus terrificus, and Rhinoclemmys punctularia. The checklist presented here provides a comprehensive database for further research on the herpetofauna of the Brazilian Atlantic Forest.

“…In recent years taxonomists have begun to integrate different lines of evidence to discover and delimit species, which is often referred to as “integrative taxonomy” (Padial & De La Riva, 2010; Schlick-Steiner et al, 2009). The application of this approach, usually done through the combination of molecular and morphological information, has improved taxonomic rigor yielding a more precise biodiversity inventory (both reducing or increasing species numbers) (Sturaro et al, 2018). In this study, we implemented an integrative taxonomy approach that combines morphological and molecular data (both mitochondrial and nuclear) to make a preliminary assessment of the species diversity and phylogenetic relationships in the genus Dichotomius.…”

Dung beetles of the subfamily Scarabaeinae are widely recognised as important providers of multiple ecosystem services and are currently experiencing revisions that have improved our understanding of higher-level relationships in the subfamily. However, the study of phylogenetic relationships at the level of genus or species is still lagging behind. In this study we investigated the New World beetle genus Dichotomius, one of the richest within the New World Scarabaeinae, using the most comprehensive molecular and morphological dataset for the genus to date (in terms of number of species and individuals). Besides evaluating phylogenetic relationships, we also assessed species delimitation through a novel Bayesian approach (iBPP) that enables morphological and molecular data to be combined. Our findings support the monophyly of the genus Dichotomius but not that of the subgenera Selenocopris and Dichotomius sensu stricto (s.s). Also, our results do not support the recent synonymy of Selenocopris with Luederwaldtinia. Some species-groups within the genus were recovered, and seem associated with elevational distribution. Our species delimitation analyses were largely congruent irrespective of the set of parameters applied, but the most robust results were obtained when molecular and morphological data were combined. Although our current sampling and analyses were not powerful enough to make definite interpretations on the validity of all species evaluated, we can confidently recognise D. nisus, D. belus and D. mamillatus as valid and well differentiated species. Overall, our study provides new insights into the phylogenetic relationships and classification of dung beetles and has broad implications for their systematics and evolutionary analyses.
