Tropiduridae is an Andean lizard endemic to Colombia, On July 17, 2014 at 13:00, an adult male was collected their presence is only confirmed in the surroundings of (CUS-R 0075) and photographed (Fig. 2C) in the the town of Bolivar, department of Cauca (type locality) bathroom of the library of the University of Santa Rosa between 1650 and 1750 m (Castro & Ayala, 1982), de Cabal - UNISARC, Vereda El Jazmín, municipality being along with S. guentheri, the only Stenocercus of Santa Rosa de Cabal (4.9119444 N; - 75.6238889 W, species present in the Cordillera Central (Castro & 1631m asl). In the same locality another specimen was Granados, 1993). According to the morphological and photographed (Fig. 2A) but not collected on July 11, molecular characters, it is closely related to S. carrioni, 2014 at 7:00 pm and a dead and deteriorated juvenile S. humeralis, S. simonsii, S. varius and S. haenschi, was found on March 31, 2015 (CUS-R 0079). In all these restricted to Andean distribution between addition, in June 21, 2014 at 21:05 we photographed a southern Ecuador and southern Colombia (Torres- fourth specimen that was in the bathroom of the School Carvajal, 2009). S. bolivarensis is recognized because it is the only one who has lateral scales strongly keeled and imbricated (Torres-Carvajal, 2007). Vanegas et al. (Vanegas et al., 2015) recently recorded a S. bolivarensis on the campus of the University of Quindio in the town of Armenia, Quindio, at 1480 m elevation. In this paper, we present four additional records, representing the northernmost distribution in the Cordillera Central, extending 370 km range distribution respect to the type locality and 44 km from the findings of Vanegas et al.

  • The Skull and Abdominal Skeleton of Stenocercus Dumerilii
    Bol. Mus. Para. Emílio Goeldi. Ciências Naturais, Belém, v. 3, n. 3, p. 203-216, set.- dez. 2008 The skull and abdominal skeleton of Stenocercus dumerilii (Steindachner, 1867) (Reptilia: Squamata: Iguania) Crânio e esqueleto abdominal de Stenocercus dumerilii (Steindachner, 1867) (Reptilia: Squamata: Iguania) Emil José Hernández-RuzI Teresa Cristina Sauer Avila-PiresII Abstract: The objective of this study is to describe the skull and abdominal skeleton of the lizard Stenocercus dumerilii (Steindachner, 1867), with emphasis on those characters used in phylogenetic studies involving the genus Stenocercus. The peculiar shape of the head (pyramidal, with a distinct canthal-superciliary ridge that ends in a prominent postsupraciliary scale) results in part from the shape of the prefrontal and postfrontal bones, both of which bear protuberances projecting towards the orbital cavity. The postfrontal bone represents the highest point of the cranium. Contrary to what has been observed in other species of Stenocercus and in most Tropiduridae, the studied specimens of S. dumerilii presented a single pair of xiphisternal inscriptional ribs (followed by a pair of posterior xiphisternal processes). Besides, they presented five pairs of postxiphisternal inscriptional ribs widely separated ventrally. One specimen (of two studied) showed the pineal foramen completely enclosed by the frontal instead of in frontoparietal suture. Keywords: Iguania. Cranial osteology. Abdominal skeleton. Stenocercus dumerilii. Resumo: O presente estudo tem por objetivo descrever o crânio e o esqueleto abdominal do lagarto Stenocercus dumerilii (Steindachner, 1867), com ênfase nos caracteres utilizados em estudos filogenéticos incluindo o gênero Stenocercus. A forma peculiar da cabeça (piramidal, com uma crista supraciliar bem demarcada e terminando em uma escama pós- supraciliar proeminente) resulta em parte do formato dos ossos pré-frontal e pós-frontal, ambos com protuberâncias que se projetam em direção à cavidade orbital.

Se cita los nombres científicos y sus autores. También se incluye la distribución por ecorregiones y departamentos, en base a la información disponible en la literatura pertinente y en la colección herpetológica del Museo de Historia Natural de la Universidad Nacional Mayor de San Marcos, Lima, Perú. ABSTRACT We presenta list of 365 reptilian species reported for Perú until April 1995. We cite the scientific names and their authors. In addition, we record their distribution by ecological regions and political departments, according to inforrna­ tion found in the pertinent literature and in the herpetological collections of the Museo de Historia Natural, Universidad Nacional Mayor de San Marcos, Lima, Perú. INTRODUCCION Hasta el presente, son escasos los trabajos que presentan una visión panorámica de los reptiles del Perú. Un primer esfuerzo fue la publicación de Carrillo (1970) donde se hace una referencia general a la fauna peruana de reptiles. En un trabajo posterior sobre nombres populares, Carrillo ( 1990) enumeró 158 especies. McNeely et al. (1990) indicaron que se conocía 297 especies del Perú, sin ofrecer una lista de ellas, y Henle & Ehrl ( 1991) presentaron una lista parcial de especies peruanas, con 104 registros. Otros autores importantes, que se han referido a la Herpetofauna peruana en sus publicacio­ nes, son Peters & Orejas-Miranda (1970), Peters & Donoso-Barros (1970) y Vanzolini (1986) para los Squamata; Medem (1983) para los Crocodylia; y Pritchard & Trebbau (1984) y Márquez (1990) para los Testudines.

The easternmost populations of the genus are poorly studied and represented in collections. Herein we describe Stenocercus quinarius sp. n. from northwestern Minas Gerais and western Bahia states, and Stenocercus squarrosus sp. n. from the southern portion of the state of Piauí, two previously poorly sampled areas in central and northeastern Brazil. The two new species seem closely related to Stenocercus dumerilii and Stenocercus tricristatus, but are easily diagnosed from all Stenocercus and from each other based on morphometric and meristic characters. The distribution patterns and possible phylogenetic affinities of the eastermost, pyramidal headed Stenocercus group are discussed, along with an overview of distribution patterns

This richness is represented by 35 species of turtles, fve crocodilians, and 437 squamates including three amphisbaenians, 197 lizards, and 237 snakes. Of these, 45 species are endemic to the Galápagos Islands and 111 are mainland endemics. The high rate of species descriptions during recent decades, along with frequent taxonomic changes, has prevented printed checklists and books from maintaining a reasonably updated record of the species of reptiles from Ecuador. Here we present Reptiles del Ecuador (http://bioweb.bio/faunaweb/reptiliaweb), a free, resource-rich online portal with updated information on Ecuadorian reptiles. This interactive portal includes encyclopedic information on all species, multimedia presentations, distribution maps, habitat suitability models, and dynamic PDF guides. We also include an updated checklist with information on distribution, endemism, and conservation status, as well as a photographic guide to the reptiles from Ecuador.

Fourteen species, including two species new to science are recognized: Stenocercus aculeatus, S. angel sp. nov., S. carrioni, S. chota sp. nov., S. festae, S. guentheri, S. haenschi, S. humeralis, S. iridescens, S. limitaris, S. ornatus, S. rhodomelas, S. simonsii, and S. varius. Of the new species, Stenocercus angel occurs at elevations of 3015-3560 m in Provincia Carchi and Provincia Sucumbios, and Stenocercus chota occurs at elevations of 1575-1940 m in the Chota Valley, Provincia Imbabura.
