Retrieving Peromyscus bullatus from P. difficilis (Rodentia: Cricetidae) through cranial morphometry in a mammal collection
Peromyscus bullatus and Peromyscus difficilis are sympatric and phenotypically similar rodents. Because of this, misidentification of both species is frequent in the field and in mammal collections. In this study, P. bullatus specimens were retrieved from the P. difficilis specimens, in the mammal collection of the Instituto de Investigaciones Biológicas of the Universidad Veracruzana, through the analysis of morphometric measurements of the tympanic bulla, proposed by González-Ruíz et al. (2005) as discrimination key variables between both species.La identificación errónea de ejemplares de Peromyscus bullatus como Peromyscus difficilis es frecuente, tanto en el campo como en las colecciones mastozoológicas, debido a que ambas especies son simpátricas y similares fenotípicamente. En este estudio se recuperaron ejemplares de P. bullatus incorrectamente catalogados como P. difficilis en la colección mastozoológica del Instituto de Investigaciones Biológicas de la Universidad Veracruzana, mediante el análisis de medidas morfométricas de la bula timpánica, propuestas por González-Ruíz et al. (2005) como claves para la discriminación entre ambas especies
Nuevas localidades del zorrillo manchado del sur Spilogale angustifrons (Carnivora, Mephitidae) en Veracruz, México/ New locations of the Southern Spotted Skunk Spilogale angustifrons (Carnivora, Mephitidae) in Veracruz, Mexico
We provide five new locations of the Southern Spotted Skunk Spilogale angustifrons Howell 1902 in Veracruz, Mexico. These records extend the known geographic distribution of this species in the Veracruz state.We provide five new locations of the Southern Spotted Skunk Spilogale angustifrons Howell 1902 in Veracruz, Mexico.

Algunas interacciones entre Dioon Edule (Zamiaceae) y Peromyscus Mexicanus (Rodentia : Cricetidae)
New state record and range extension of the Big Crested Mastiff Bat, Promops centralis Thomas, 1915 (Chiroptera, Molossidae), in Veracruz, Mexico
The diversity of bats in the Mexican state of Veracruz is high, comprising 89 species. Many of these species deserve special attention because either they remain underrepresented in collections, or they are known from fewer than 5 localities. We confirm the presence of the Big Crested Mastiff Bat (Promops centralis) in Veracruz, and provide additional occurrence records that extend the known geographic distribution of this species by 216 km to the north from previously known sites. Our new record represents the northernmost record of the species on the coastal plain of the Gulf of Mexico. Our findings highlight the presence of gaps in past surveys of mammalian diversity in Veracruz
Registros notables de mamíferos para Campeche, México/Noteworthy records of mammals to Campeche, Mexico
Se reportan ocho nuevos registros de mamíferos para Campeche, México, de los cuales siete son del orden Chiroptera y uno del orden Carnivora. A su vez, se confirma la presencia de Artibeus watsoni, Cynomops mexicanus (Chiroptera) y Lontra longicaudis (Carnivora) en el Estado, con lo cual la riqueza de especies de murciélagos se incrementa de 48 a 55 y de carnívoros de 16 a 17.We collected eight new records of mammal species from Campeche, México, including seven bats (Order Chiroptera) and one carnivore (Order Carnivora). We also confirmed the presence in the state of Artibeus watsoni, Cynomops mexicanus (Chiroptera) and Lontra longicaudis (Carnivora). Hence, for Campeche bat species richness increased from 48 to 55 and carnivores 16 to 17
