Beaucarnea olsonii is described and illustrated from tropical deciduous forests of SW Puebla, Mexico. The new species can be distinguished from other Beaucarnea species by its massively swollen base that abruptly tapers into slender branches, by its conspicuously long stigma, and by its pedicel articulation that occurs at 2/3 of the length of the pedicel below the flower. With this new addition, the total number of endemic species of Beaucarnea for Mexico increases to 10, making this country the greatest center of diversification and endemism for the genus. We also provide a distribution map and a conservation status recommendation for the new species, as well as a key to the Beaucarnea species of southern central Mexico.

During a helminthological examination of flathead knob-scaled lizards, Xenosaurus platyceps King and Thompson 1968, from Mexico, 4 of 10 were found to harbor 56 (14 male, 42 female) nematodes of an undescribed species of Spauligodon Skrjabin, Schikhobalova and Lagodovskaja, 1960. The lizard family Xenosauridae is composed of two well-differentiated genera: Shinisaurus in southern China and Xenosaurus in Mexico and Guatemala (Pérez-Ramos et al., 2000). Xenosaurus platyceps is a stocky, medium-sized species endemic to the Mexican state of Tamaulipas where it occurs in dry oak and tropical deciduous forests of the Sierra Madre Oriental (Flores-Villela 1993; Flores-Villela and Gerez, 1994). The ecology of X. platyceps has been studied (Lemos-Espinal, 1997), but, to our knowledge, there are no helminthological reports for it.

AbstractNew specimens from Sinaloa, Mexico, as well as two older specimens, show that both adult and recently fledged Lucy's Warblers (Vermivora luciae) often move far south of their breeding grounds to molt in the tropical deciduous forests of northwestern Mexico. Remarkably, the first preformative (= first prebasic) molt is complete in Lucy's Warblers, including the replacement of flight feathers, primary coverts, and rectrices; thus, previous aging criteria based on the wear and appearance of these feathers are invalid. We suggest that the recent conclusion that Lucy's Warblers molt on their breeding grounds (Voelker and McFarland 2002) is an artifact of more collecting in the southwestern United States than in western Mexico during late summer. An index of relative collecting in Mexico and the United States, as well as data from constant-effort mist netting, suggest that most Lucy's Warblers move south to molt.Tasas versus Conteos: Mudas de Otoño de Vermivora luciae

AbstractPeromyscus melanophrys is a Mexican endemic distributed in seasonal tropical forests and semiarid lands. Molecular work based on mitochondrial and nuclear markers proposed the existence of four haplogroups within P. melanophrys. Peromyscus mekisturus (Puebla deer mouse) was included in one of these haplogroups. We tested the consistency between this hypothesis and external morphology, quantitative and qualitative cranial attributes, and ecological data for a sample of 1,155 specimens spanning the species distribution. We found ecological and morphological consistency with the phylogenetic pattern for P. melanophrys but not for P. mekisturus. We reassessed the taxonomic and nomenclatural status of the populations and type specimens formerly included in P. melanophrys. We concluded that these populations constitute four species: P. zamorae (Zamora deer mouse), distributed in the Mexican Plateau at elevations > 1,500 m; P. micropus (small-footed deer mouse), from lowland tropical deciduous forests of the San Pedro-Mezquital and Lerma-Santiago basins in western Mexico; P. melanophrys (black-eyed deer mouse) from lowland tropical deciduous forests of southeastern Mexico as far as eastern Oaxaca; and P. leucurus (Tehuantepec deer mouse), partially sympatric with P. melanophrys but reaching as far as Chiapas. Data on P. mekisturus were contradictory, and thus was kept as a valid species.Peromyscus melanophrys es un roedor endémico de México, distribuido en bosques tropicales caducifolios y regiones semiáridas. Datos moleculares usando marcadores mitocondriales y nucleares indicaron la existencia de cuatro haplogrupos dentro de P. melanophrys. Peromyscus mekisturus (ratón de Puebla) se incluyó dentro de uno de éstos. Con base en una muestra de 1,155 ejemplares de toda la distribución de la especie, se examinó si esta hipótesis era consistente con datos de morfología externa y craneal, morfometría e información ecológica. Se encontró coincidencia para P. melanophrys pero no para P. mekisturus. Estos resultados hicieron necesaria la reevaluación del estado taxonómico y nomenclatural de las poblaciones incluidas en P. melanophrys. Se concluye que existen cuatro especies dentro de lo que se conocía como P. melanophrys: P. zamorae (ratón de Zamora) distribuido en el Altiplano Mexicano a elevaciones ≥ 1,500 m; P. micropus (ratón de pata pequeña) distribuido en los bosques tropicales caducifolios de las cuencas San Pedro-Mezquital y Lerma-Santiago en el occidente de México; P. melanophrys (ratón de ojo oscuro) de los bosques y matorrales tropicales caducifolios del sureste de México, al menos hasta el este de Oaxaca, y P. leucurus (ratón de Tehuantepec) parcialmente simpátrico con P. melanophrys pero llegando hasta el estado de Chiapas. La información disponible no permitió asignar a P. mekisturus a ninguno de los grupos y por tanto se sigue considerando como especie válida.
