New records of Diploglossus monotropis (Kuhl, 1820) (Squamata: Anguidae) from Urabá and Magdalena River valley, Colombia, with an updated geographic distribution map

Abstract

Based on recent records, published data, and review of specimens deposited in scientific collections, we present an updated map of the geographic distribution of Diploglossus monotropis in Colombia. Our data show that this species has a wide geographical distribution, including the Pacific versant of the Cordillera Occidental, the inter-Andean valley of the Magdalena River, and the Caribbean lowlands of northern Colombia.

Imantodes inornatus (Boulenger, 1886) (Squamata: Dipsadidae): expansion of known range and first records from the Magdalena River valley, Colombia

“…This specimen presents 17-17-15 dorsal scales, 196 ventrals, 105 subcaudals, eight supralabials (3-5 contacting the orbit), nine infralabials (1-5 contacting shinshields), one preocular, and one postocular scales. (Savage, 2002;Castaño-Mora et al, 2004;Rojas-Morales, 2012;Díaz-Ayala et al, 2015;Angarita-Sierra & Lynch, 2017). The distribution of I. inornatus in the middle Magdalena River valley, particularly in the Nechí, Carare and Lebrija districts (Chocó-Magdalena biogeographic province), supports the known shared distribution of some amphibians and reptiles between the Pacific and middle Magdalena humid forests, as has been discussed by other authors (Hernandez-Camacho et al, Accelerated habitat loss and degradation by different activities in the middle Magdalena River valley (i. e. cattle rising, illegal crops, and energy projects), have modified the natural landscape pattern.…”

First record of the goo-eater snake, Geophis nigroalbus Boulenger, 1908 (Serpentes, Dipsadidae), in the Magdalena Valley, Cordillera Oriental of Colombia

“…Although G. nigroalbus was previously only known from the Pacific versant of the Cordillera Occidental, its occurrence in the Middle Magdalena Valley is not unexpected. Many Central American species of reptiles that reach the western region of Colombia have also been reported to inhabit the middle region of the Magdalena Valley, such as Rhinobothryum bovalli (Andersson, 1916), Diploglossus monotropis (Kuhl, 1820), Sibon annulatus (Günther, 1872), Imantodes inornatus (Boulenger,1896) (Rojas-Morales 2012, Diaz-Ayala et al 2015, Meneses-Pelayo et al 2016, Echavarría et al 2018. This exchange of fauna between the Choco region and the Middle Magdalena Valley is possible because of Pleistocene refuges of humid tropical rainforest (Hernández-Camacho et al 1992).…”

Colección de reptiles no aves (Reptilia), Museo de Historia Natural de la Universidad de Caldas, Colombia

“…La Colección de Reptiles del MHN-UCa, ha jugado un papel importante en el conocimiento de los reptiles del departamento de Caldas Rojas-Morales et al, 2014Serna-Botero & Ramírez-Castaño, 2017). En los últimos diez años, 20 publicaciones han incluido ejemplares de la Colección de Reptiles del MHN-UCa (Sánchez-Pacheco, 2010;Rojas-Morales & González-Durán, 2011;Ossa et al, 2012;Rojas-Morales, 2012;Rojas-Morales et al, 2013, 2014Díaz-Ayala et al, 2015Zuluaga-Isaza et al, 2015;Marín-Martínez et al, 2017;Serna-Botero & Ramírez-Castaño, 2017;Cárdenas-Ortega et al, 2018;Herrera-Lopera et al, 2018;Serna-Botero et al, 2019;Meza-Joya et al 2020). Además, el estado de salud de la Colección de Reptiles fue evaluado previamente en el año 2017 (256 especímenes para la fecha), presentando valores satisfactorios para toda la colección (Serna-Botero & Ramírez-Castaño, 2017).…”
