The colubrid snake Rhadinaea cuneata (Veracruz Graceful Brown Snake) was known previously from three individuals. In 2011 we collected two additional specimens in Yohualapa Cave, southeast Puebla, México. We provide the first description of color pattern of this species in life as well as additional natural history information. Copyright 2014 Society for the Study of Amphibians and Reptiles. Source

Species diversity is largely underestimated by current taxonomy, precluding a precise understanding of evolutionary pro-cesses. Genetic data have increased our understanding of that cryptic diversity, and multilocus studies are now desirable. In this study, we used mitochondrial and nuclear DNA sequences to evaluate the taxonomic status of the western Mexico's populations of Phaethornis longirostris. We found differences of 4.2 % in mtDNA and different alleles for one nDNA locus between western and eastern Mexican populations. Molecular and morphological evidence support the separation of these populations (P. l. mexicanus and P. l. griseoventer) as the species Phaethornis mexicanus Hartert 1897. Phaetho-rnis mexicanus is endemic to western Mexico and sister to the remaining populations of P. longirostris. The speciation of P. mexicanus probably occurred around 880,000 years ago by a vicariant event involving climatic-vegetational changes. Copyright © 2013 Magnolia Press. Source

We set the information available for a comprehensive list of the state of Morelos Rhopalocera: 331 taxa specific level, contained in 154 genera, 18 subfamilies and 5 families from 29 981 lepidopterists specimens from Mexican and foreign collections contained in the megabase MARIPOSA, it is specialized in wildlife inventories. Based on this, we performed a historical sketch of collecting and collectors, highlighting the work in the state since the sixteenth century. We compared the richness with contiguous states, we found a greater similarity with the state of Guerrero, with more than 90%. We found that Cuernavaca is the town with more diversity, as it contains more than half of the species in the state, 21 sites have been successfully collected, they represented in 95% of the Papilionoidea. Municipalities best studied were Tepoztlan, Tlaquiltenango and Huitzilac. Morelos is highlighted by the percentage of taxa endemic to Mexico it represents one third of the total species endemic for the country. Source

We describe and compare the egg chorion of five species of three genera of Pierinae: Pieriballia, Itaballia, and Perrhybris. Their characterizations and illustrations include the main structural features: number and arrangement of longitudinal axes (short and long), and quantification of ribs or cells, projections and vestiges or reminiscent ribs. Also, we describe the color and size of the egg. We typify two egg models: elongated ellipsoidal or fusiform and oblong ellipsoidal, both with projections in the apical area, around the micropyle. Comparisons are made between features present in different species and genera. We discuss their phylogenetic and taxonomic implications. Source
