Xenosaurus Tzacualtipantecus. the Zacualtipán Knob-Scaled Lizard Is Endemic to the Sierra Madre Oriental of Eastern Mexico
Xenosaurus tzacualtipantecus. The Zacualtipán knob-scaled lizard is endemic to the Sierra Madre Oriental of eastern Mexico. This medium-large lizard (female holotype measures 188 mm in total length) is known only from the vicinity of the type locality in eastern Hidalgo, at an elevation of 1,900 m in pine-oak forest, and a nearby locality at 2,000 m in northern Veracruz (Woolrich- Piña and Smith 2012). Xenosaurus tzacualtipantecus is thought to belong to the northern clade of the genus, which also contains X. newmanorum and X. platyceps (Bhullar 2011). As with its congeners, X. tzacualtipantecus is an inhabitant of crevices in limestone rocks. This species consumes beetles and lepidopteran larvae and gives birth to living young. The habitat of this lizard in the vicinity of the type locality is being deforested, and people in nearby towns have created an open garbage dump in this area. We determined its EVS as 17, in the middle of the high vulnerability category (see text for explanation), and its status by the IUCN and SEMAR- NAT presently are undetermined. This newly described endemic species is one of nine known species in the monogeneric family Xenosauridae, which is endemic to northern Mesoamerica (Mexico from Tamaulipas to Chiapas and into the montane portions of Alta Verapaz, Guatemala). All but one of these nine species is endemic to Mexico.

This new species, Lepidophyma cuicateca sp. nov., is known from two areas in the Cuicatlan Valley. Lepidophyma cuicateca sp. nov. is a member of the Lepidophyma gaigeae species Group and is characterized by its small body size, small size of tubercular body scales, poorly differentiated caudal whorls and interwhorls, and relatively large dorsal, ven- tral and gular scales. It lives in shady places, below rocks along the Apoala River, and is commonly found in plantain, sapodilla, cherimoya, mango and coffee plantations, as well as tropical deciduous forest. The description of L. cuicateca sp. nov. increases the number of species in the L. gaigeae Group to five. Key words: Squamata, Lepidophyma gaigeae Group, Lepidophyma cuicateca sp. nov., new species, Xantusiidae, Mex- ico, Oaxaca Resumen Se describe una nueva especie de Lepidophyma para la parte oaxaqueña de la reserva de la biosfera de Tehuacán- Cuicatlán.

Iguanidae: Hoplocercinae) from Southwestern Ecuador
Volume 48(20):227-235, 2008 A new species of ENYALIOIDES (Iguanidae: Hoplocercinae) from southwestern Ecuador Omar Torres-Carvajal1,2 Ana Almendáriz3 Jorge Valencia4 Mario Yánez-Muñoz5 Juan P. Reyes5 ABStract We describe a new species of Enyalioides from lowland cloud forests in southwestern Ecuador. This represents the third species in the genus known to occur west of the Andes in South America; the other two species are E. heterolepis and E. oshaughnessyi. Among other characters, the new species can be distinguished from other members in the genus by having small, keeled, paravertebrals; a series of skin folds on the lateral aspects of body and neck; size-homogeneous scales on body and limbs; distinct caudal segments; and an extensive dark patch on the gular region of adult males. Morphological similarity suggests that the new species, which we call E. touzeti, is closely related to E. oshaughnessyi. Keywords: Ecuador, Enyalioides, Hoplocercinae, Iguania, new species.

Multi-National Conservation of Alligator Lizards
MULTI-NATIONAL CONSERVATION OF ALLIGATOR LIZARDS: APPLIED SOCIOECOLOGICAL LESSONS FROM A FLAGSHIP GROUP by ADAM G. CLAUSE (Under the Direction of John Maerz) ABSTRACT The Anthropocene is defined by unprecedented human influence on the biosphere. Integrative conservation recognizes this inextricable coupling of human and natural systems, and mobilizes multiple epistemologies to seek equitable, enduring solutions to complex socioecological issues. Although a central motivation of global conservation practice is to protect at-risk species, such organisms may be the subject of competing social perspectives that can impede robust interventions. Furthermore, imperiled species are often chronically understudied, which prevents the immediate application of data-driven quantitative modeling approaches in conservation decision making. Instead, real-world management goals are regularly prioritized on the basis of expert opinion. Here, I explore how an organismal natural history perspective, when grounded in a critique of established human judgements, can help resolve socioecological conflicts and contextualize perceived threats related to threatened species conservation and policy development. To achieve this, I leverage a multi-national system anchored by a diverse, enigmatic, and often endangered New World clade: alligator lizards. Using a threat analysis and status assessment, I show that one recent petition to list a California alligator lizard, Elgaria panamintina, under the US Endangered Species Act often contradicts the best available science. -

Habitat Selection of the Desert Night Lizard (Xantusia Vigilis) on Mojave Yucca (Yucca Schidigera) in the Mojave Desert, California
Habitat selection of the desert night lizard (Xantusia vigilis) on Mojave yucca (Yucca schidigera) in the Mojave Desert, California Kirsten Boylan1, Robert Degen2, Carly Sanchez3, Krista Schmidt4, Chantal Sengsourinho5 University of California, San Diego1, University of California, Merced2, University of California, Santa Cruz3, University of California, Davis4 , University of California, San Diego5 ABSTRACT The Mojave Desert is a massive natural ecosystem that acts as a biodiversity hotspot for hundreds of different species. However, there has been little research into many of the organisms that comprise these ecosystems, one being the desert night lizard (Xantusia vigilis). Our study examined the relationship between the common X. vigilis and the Mojave yucca (Yucca schidigera). We investigated whether X. vigilis exhibits habitat preference for fallen Y. schidigera log microhabitats and what factors make certain log microhabitats more suitable for X. vigilis inhabitation. We found that X. vigilis preferred Y. schidigera logs that were larger in circumference and showed no preference for dead or live clonal stands of Y. schidigera. When invertebrates were present, X. vigilis was approximately 50% more likely to also be present. These results suggest that X. vigilis have preferences for different types of Y. schidigera logs and logs where invertebrates are present. These findings are important as they help in understanding one of the Mojave Desert’s most abundant reptile species and the ecosystems of the Mojave Desert as a whole. INTRODUCTION such as the Mojave Desert in California.

Monster of the Desert by Guy Belleranti
Name: __________________________________ Monster of the Desert by Guy Belleranti Imagine a monster with a big head, a powerful bite, strong digging claws, and a forked tongue. The monster is black with yellow or pink scales all over it's body. If you've been to the deserts of southwestern U.S. and northwestern Mexico, you may have seen such an animal, known as the Gila (HEE-la) monster. Growing up to two feet long, it is the largest of all lizards native to the United States. The Gila monster is one of only two venomous lizards living in North America. The other is the similar looking Mexican beaded lizard. Named after Arizona’s Gila River, the colorful Gila monster makes its home in hot, dry, rocky desert landscapes. Despite its scary name the Gila monster is actually a shy animal. It doesn’t bravely leap out at people, spitting venom. Instead, the solitary Gila monster spends most of its time in underground burrows or hiding under rocks. A Gila monster can go for months without eating. How can it do this? Well, it lives on the fat it has stored in its tail and abdomen. The most likely time to see this animal is in the spring when it comes out to hunt for food. While it is nocturnal (coming out at night) for most of the year, the Gila monster does occasionally venture out in the sunshine during the spring months to sun itself on desert rocks. The Gila monster doesn’t consider people food. We’re way too big. -
