A phantom on the trees: Integrative taxonomy supports a reappraisal of rear-fanged snakes classification (Dipsadidae: Philodryadini)

Parasitic Fauna of Captive Snakes (Serpentes, Colubridae) from Northeastern Argentina

“…According to Jacobson (2007), mites are the most common ectoparasites in captive snakes; however, in this study we only detected the tick Amblyomma dissimile. This tick species is often reported parasitizing reptiles (Nascimento et al, 2017), and it has been reported in Philodryas ( P. baroni: Burridge, 2010; Guglielmone and Nava, 2010) prior to our record in Pseudablabes patagoniensis (formerly Philodryas patagoniensis; see Melo-Sampaio et al, 2020).…”

Systematic review of the polychromatic ground snakesAtractus snethlageaecomplex reveals four new species from threatened environments

“…Prior to this work, the hemipenis of A. snethlageae was never illustrated or even properly described, although this character is very useful for species delimitation (and identification) in the genus Atractus (Passos et al, 2018). We describe the male genitalia based on the paratype of A. snethlageae -Sampaio et al, , 2020-Sampaio et al, , 2021Rojas et al, 2018).…”

“…Atractus akerios , A. nawa, and A. ukupacha have apparently restricted distributions and probably through denser sampling it is possible to detect other distinct lineages also with narrow ranges of distribution. Many recent studies have pointed that the diversity of the Amazonian herpetofauna is underestimated due to cryptic diversity (Melo‐Sampaio et al, 2018, 2019, 2020, 2021; Rojas et al, 2018). The increasing efforts to accurately delimit species in the Neotropics have profited from the museum specimens with available tissue samples for molecular studies, allowing falsification of previous hypotheses with premature or misguided taxonomic decisions.…”

“…Studies in the region are crucial to improve the knowledge about impacts on the biota experiencing fast change on vegetation covering and land use. However, we are just filling some gaps in the knowledge on snake diversity from western Amazonia (Melo‐Sampaio et al, 2021; Nogueira et al, 2019).…”
