Difficulties in establishing a sizeable breeding colony make it necessary to find alternatives that increase the reproductive efficiency of captive individuals. Here, we tested a semen collection protocol and characterize the seminal parameters of captive M. corallinus. We collected semen during the mating season of the species (spring-summer) and were successful at every first attempt. Spermatozoa of M. corallinus are elongated and filiform, and the midpiece is the longest part. Sperm motility and progressive motility reached values of 80% and 3.6%, respectively, during the reproductive period of this species. Our results will allow further studies to improve husbandry, reproductive rates, and conservation of captive M. corallinus. Key Words.—reproduction; reproductive biotechniques; reptiles; sperm parameters INTRODUCTION and capture rates of individual M. corallinus in the wild (Roze 1996) are worrisome and also make it difficult to Reproductive biotechniques have been useful in establish a breeding colony with a substantial number implementing conservation projects for endangered of animals. -

RESUMEN En el Estado de Veracruz se distribuyen cinco especies de coralillos verdaderos del género Micrurus y 14 especies de coralillos falsos de diferentes géneros de colúbridos, lo que hace más probables los encuentros con coralillos falsos. Sin embargo, la identificación por patrones de color entre coralillos verdaderos y falsos no es confiable, a causa de la variación del color inter e intraespecífica y a las semejanzas de coloración entre varias especies de estas dos familias de serpientes. Palabras clave: Colubridae, Elapidae, Micrurus, mimetismo, patrón de coloración, Veracruz ABSTRACT Five species of coral snakes genus Micrurus, and 14 species of mimic false coral snakes of different colubrid genera ocurr in Veracruz, making encounters with false coral snakes more likely. However, positive identification by color pattern between coral snakes and their mimics is not reliable because of inter and intraspecific color variation and similarities in coloration between several species of these two snake families. -

DEFINING SUITABLE HABITAT AND CONSERVATION STATUS FOR THE TUCSON SHOVEL-NOSED SNAKE (CHIONACTIS ANNULATA KLAUBERI) IN THE SONORAN DESERT Curtis M. Bradley, Center for Biological Diversity, Tucson, AZ; and Philip C. Rosen, University of Arizona, Tucson, AZ. Abstract.— The Tucson shovel-nosed snake (Chionactis annulata klauberi) is a small specialized colubrid associated with sandy loams of the elevated portions of the Lower Colorado River Valley Sonoran Desert in central Arizona. This taxon is a recently redefined subspecies based on genetic data, and may be extirpated in the Tucson region, including the type locality. A recent (USFWS 2014) decision against protecting it was based in part on an expansive definition of its geographic range and a habitat model. Here, we redefine the subspecies distribution by uniting published results of mitochondrial and nuclear DNA. We then present a new ecologically-based model of its original and current habitat using the machine learning algorithm Random Forests. The new model accurately matches known and estimated presence-absence data for this taxon, and is consistent with morphometrics and, largely, with color pattern variation. It estimates 60% less available habitat than the USFWS model. We estimate that 39% of the 1,255,946 ha (3,103,505 acres) of original habitat has been converted to urban developments, roads, agriculture, or otherwise altered non-habitat. Of the remaining 770,971 ha (1,905,108 acres), 60% is susceptible to habitat conversion in the region, with only 10.9% of habitat having current legal protection. Ongoing and projected urbanization and energy development in its flatland desert habitat present a bleak future for this subspecies. -

Tantilla cascadae is a rare centipede snake that inhabits western Mexico and is only known from two localities and three specimens. In this work we report two new specimens from a new locality in the municipality of Tamazula de Gordiano, Jalisco, Mexico. We assess the biogeographical and physiographical component of the species’ distribution, and discuss the conservation status of the species proposing a new IUCN conservation assessment of Endangered.

(Tantilla Oolitica) in Miami-Dade and Monroe Counties, Florida
Assessment of the Status and Distribution of the Endemic Rim Rock Crowned Snake (Tantilla oolitica) in Miami-Dade and Monroe Counties, Florida Final Report Grant Agreement #401817G006 Kirsten N. Hines and Keith A. Bradley July 10, 2009 Submitted by: The Institute for Regional Conservation 22601 S.W. 152 Avenue, Miami, FL 33170 George D. Gann, Executive Director Submitted to: Paula Halupa Fish and Wildlife Biologist U.S. Fish and Wildlife Service 1339 20th Street Vero Beach, FL 32960 1 Project Background: The rim rock crowned snake (Tantilla oolitica) is one of three species of small, burrowing snakes within the genus Tantilla found in Florida. Of the more than 40 species of this genus extending from the southeastern United States down to northern Argentina in South America, T. oolitica has the most limited distribution (Wilson 1982, Scott 2004). Confined to the Miami Rock Ridge in southeastern Miami-Dade County and parts of the Florida Keys in Monroe County, this species has been greatly affected by the rapid urbanization of this area. By 1975 it had already made the Florida State list of threatened species and it is currently considered a candidate for the Federal Endangered Species List. Traditionally, T. oolitica habitat included rockland hammocks and pine rocklands. Less than 2% of the pine rocklands on the Miami Rock Ridge currently remain (Snyder et. al 1990, USFWS 1999) and rockland hammocks both in Miami-Dade County and throughout the Florida Keys have been reduced to less than half their original extent and continue to face threat of development (Enge et. al 1997, USFWS 1999). -
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. Photo by Christian Berriozabal-Islas. Amphib.

Adults of Montivipera xanthina generally feed on small mammals, birds and lizards, although juveniles often prey on orthopterans and centipedes. During the fieldwork carried out on May 28, 2001, there were recorded parts of the scorpion body Protoiurus kraepelini (von Ubisch, 1922) in excrements of an adult female of M. xanthina in Muğla (southwestern Turkey).
