Other Contributions NATURE NOTES Amphibia: Caudata Ambystoma ordinarium. Predation by a Black-necked Gartersnake (Thamnophis cyrtopsis). The Michoacán Stream Salamander (Ambystoma ordinarium) is a facultatively paedomorphic ambystomatid species. Paedomorphic adults and larvae are found in montane streams, while metamorphic adults are terrestrial, remaining near natal streams (Ruiz-Martínez et al., 2014). Streams inhabited by this species are immersed in pine, pine-oak, and fir for- ests in the central part of the Trans-Mexican Volcanic Belt (Luna-Vega et al., 2007). All known localities where A. ordinarium has been recorded are situated between the vicinity of Lake Patzcuaro in the north-central portion of the state of Michoacan and Tianguistenco in the western part of the state of México (Ruiz-Martínez et al., 2014). This species is considered Endangered by the IUCN (IUCN, 2015), is protected by the government of Mexico, under the category Pr (special protection) (AmphibiaWeb; accessed 1April 2016), and Wilson et al. (2013) scored it at the upper end of the medium vulnerability level. Data available on the life history and biology of A. ordinarium is restricted to the species description (Taylor, 1940), distribution (Shaffer, 1984; Anderson and Worthington, 1971), diet composition (Alvarado-Díaz et al., 2002), phylogeny (Weisrock et al., 2006) and the effect of habitat quality on diet diversity (Ruiz-Martínez et al., 2014). We did not find predation records on this species in the literature, and in this note we present information on a predation attack on an adult neotenic A. ordinarium by a Thamnophis cyrtopsis. On 13 July 2010 at 1300 h, while conducting an ecological study of A. -

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.

Species lists updates and accurate information on the geographic distribution of species are necessary for baseline studies in ecology and conservation of these sites. Here, we present an updated list of the diversity of amphibians and reptiles in the Lacandona region, and actualized information on their distribution and conservation status. Although some studies have discussed the amphibians and reptiles of the Lacandona, most herpetological lists came from the northern part of the region, and there are no confirmed records for many of the species assumed to live in the region. -
