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, Mexico. We provide the first description of color pattern of this species in life as well as additional natural history information.

A new species of Tantilla is described from a single specimen obtained from Volcan Ceboruco, southern Nayarit, Mexico. The new species closely resembles other species of the Tantilla calamarina group. With the addition of the taxon described herein, the calamarina group now contains seven species, T. calamarina, Tantilla cascadae, Tantilla coronadoi, Tantilla deppei, Tantilla sertula, Tantilla vermiformis, and the new species described herein. Collectively, members of the group are distributed along the Pacific versant of Middle America in three disjunct regions: (1) from northern Sinaloa to Guerrero, including the Tres Marias Islands; (2) the Balsas Basin of Morelos, Puebla, Distrito Federal, and the State of Mexico; and (3) from El Salvador to northwestern Costa Rica. We provide a small list of specimens collected in the highlands of Nayarit, and report Lithobates psilonota, Ambystoma rosaceum, Elgaria kingi, Plestiodon lynxe and Rhadinaea hesperia for the first time from the state. We report t...

A new species of Plectrohyla is described from the Sierra de Miahuatlan in southern Oaxaca, Mexico. It is known from a single adult female obtained from pine-oak forest at 2550 m. The new species is similar to Plectrohyla cembra in size, habitus, and in having a partially concealed tympanum but differs most notably in aspects of color pattern, hand morphology, head shape, and palatine features.

A new terrestrial species of Pseudoeurycea is described from the mountains of the Mixteca region of Oaxaca. Compared with other members of the genus, the new species is relatively slender and short-legged. The background color of the dorsum of this species is dark gray with reddish-brown spots. The Mixteca region of Oaxaca has long been poorly explored biologically, and the knowledge of the distribution of its salamanders is scarce. Herein, we present new information regarding salamanders species in this region.

Five specimens of Lepidophyma radula were collected recently near San Pablo Villa de Mitla, Oaxaca. The species had not been collected since its description in 1942. A redescription of the holotype is presented, including new and important taxonomic characters proposed by other workers.
