A new green anole lizard of the "Dactyloa" clade (Squamata: Dactyloidae) from the Magdalena river valley of Colombia 

Abstract

We describe a new species of Anolis from the Magdalena river valley in Colombia. The new species is morphologically similar to Anolis ibanezi and A. chocorum, but differs in body and dewlap color, and head scalation. We performed an exploratory multivariate analysis based on 15 morphological characteristics of the new species and A chocorum and found that differences between both species are mainly associated with head dimensions. A phylogenetic analysis based on morphological characters suggests that the new species is nested within the "Dactyloa" clade of Anolis. Finally, we discuss phylogenetic relationships and biogeographical affinities based in its distribution.

Rhynchotermes armatus, a new mandibulate nasute termite (Isoptera, Termitidae, Syntermitinae) from Colombia

“…The Magdalena River Valley lies between the central and eastern ranges of the Colombian Andes and is host to various endemic faunas including birds (Cracraft 1985), fishes (Anderson and Maldonado‐Ocampo 2011), frogs (Ospina-Sarria et al 2015), lizards (Velasco and Hurtado-Gómez 2014), and insects (Huertas et al 2009; Padilla-Gil 2015). Rhynchotermes armatus is apparently another endemic species from the Magdalena River Valley.…”

A genomic assessment of species boundaries and hybridization in a group of highly polymorphic anoles (distichusspecies complex)

“…Because the dewlap is thought to play a critical role in species recognition and sexual selection, dewlap divergence has been used as a proxy for reproductive isolation and is often used to delimit species boundaries (e.g. Lotzkat, Bienentreu, Hertz & Köhler, ; Poe & Yañez‐Miranda, ; Velasco & Hurtado‐Gómez, ). However, in the case of A. distichus and a few other polymorphic anole species, populations with strikingly different dewlaps have been recognized as subspecies or unnamed geographic populations rather than distinct species because they appear to hybridize where they come into contact (Heatwole, ; Schwartz, ; Schwartz, ; Underwood & Williams, ).…”

Non-volant mammals from the protected areas associated to hydroelectric projects on the eastern slope of the northern Cordillera Central, Colombia

“…The northern Cordillera Central is recognized as a region with high biogeographic value because of the confluence of biological elements from different areas (e.g., Chocó, Central America, and inter-Andean valleys), resulting in high levels of richness and endemism of plants and vertebrates Cuervo et al 2008aCuervo et al , 2008bIdárraga & Callejas 2011). Likewise, during the last decade the discovery of 10 new species, including birds, frogs, snakes and lizards, have come from this region (Cuervo et al 2001;Passos et al 2009;Bravo-Valencia & Rivera-Correa 2011;Velasco et al 2010;RiveraCorrea & Gutierrez-Cárdenas 2012;Rivera-Correa & Faivovich 2013;Rivera-Prieto et al 2014).…”
