Descripción de un nuevo género de quiróptero neotropical de la familia Molossidae
Se describe un nuevo género de quiróptero de la familia Molossidae del
Nuevo Mundo, al que se denomina Cabreramops y cuya especie tipo es
Molossops aequatorianus Cabrera. Los caracteres principales de este nuevo género son: La presencia de dos pares de incisivos inferiores y uno de
premolares superiores. Incisivos superiores que no se proyectan hacia adelante. Parte anterior del paladar completa sin emarginación. Orejas casi
unidas sobre la frente.A new genus of Chiroptera of the Molossidae family of the New World is described, giving if the name Cabreramops. The type species is Molossops aequatorianus Cabrera, 1917. Since the time of the description of this species, made on the basis of four specimens, no new material has been
reported. Only the skin of the type and the skull and skin of a paratype are actually known to exist and both are deposited in the Museo Nacional de
Ciencias Naturales of Madrid. The features diagnostic of this new genus are
the following: Anterior bases of ears near together on forehead. Upper lip
wrinkled though more weekly than in Tadarida. No keel-like ridge from behind muzzle to origin of ears. Second phalanx of digit IV slightly shorter than the first.
Dental formula i (1-1)/(2-2), c (1-1)/(1-1), pm (1-1)/(2-2), m (3-3)/(3-3). Converging upper incisors widely separated at base and in contacy in the distal half, scarcely proyected ahead of the canine (very similar in form and proportions to Molossus and Cheiromeles). Lower premolars nearly equal; the anterior, slightly smaller, is not being compressed between the canine and posterior premolar. Upper molars essentially normal, the two first ones with hipocone though not very large, the third reduced, missing the third commisure.Saginal crest absent, lachrimal ridge poorly developed. Anterior portion of palate entire without emargination. Basisphenoid pits oval well developed. Cabreramops is also compared here with other molossid genera, giving the main differential characteristics among them
Expert range maps of global mammal distributions harmonised to three taxonomic authorities
Aim: Comprehensive, global information on species' occurrences is an essential biodiversity variable and central to a range of applications in ecology, evolution, biogeography and conservation. Expert range maps often represent a species' only available distributional information and play an increasing role in conservation assessments and macroecology. We provide global range maps for the native ranges of all extant mammal species harmonised to the taxonomy of the Mammal Diversity Database (MDD) mobilised from two sources, the Handbook of the Mammals of the World (HMW) and the Illustrated Checklist of the Mammals of the World (CMW). Location: Global. Taxon: All extant mammal species. Methods: Range maps were digitally interpreted, georeferenced, error-checked and subsequently taxonomically aligned between the HMW (6253 species), the CMW (6431 species) and the MDD taxonomies (6362 species). Results: Range maps can be evaluated and visualised in an online map browser at Map of Life (mol.org) and accessed for individual or batch download for non-commercial use. Main conclusion: Expert maps of species' global distributions are limited in their spatial detail and temporal specificity, but form a useful basis for broad-scale characterizations and model-based integration with other data. We provide georeferenced range maps for the native ranges of all extant mammal species as shapefiles, with species-level metadata and source information packaged together in geodatabase format. Across the three taxonomic sources our maps entail, there are 1784 taxonomic name differences compared to the maps currently available on the IUCN Red List website. The expert maps provided here are harmonised to the MDD taxonomic authority and linked to a community of online tools that will enable transparent future updates and version control.Fil: Marsh, Charles J..

A study of Valverde's Lizard, Algyroides marchi (Reptilia, Lacertidae)
En este trabajo los autores hacen un estudio sobre Algyroides marchi, Valverde (1958), La primera parte se refiere a la biometría, folidosis y colorido de una población de Riopar (Sierra de Alcaraz) y se obtienen los siguientes resultados:
Biometría.-Los machos viejos alcanzan mayor peso que las hembras, tienen además el pileo y los miembros más grandes que ellas. Las hembras viejas alcanzan mayor longitud cabeza más cuerpo. En ambos sexos la longitud de la oola es semejante.
Folidosis.-Es prácticamente igual en ambos sexos. La única diferencia significativa radica en el número de series transversales de escamas ventrales que en los machos es de 25,3 y en las hembras de 27,9.
Colorido.-Los machos están en general más pigmentados que las hembras. Hay un buen porcentaje de estas que conservan el diseño juvenil. En ambos sexos el abdomen es de color amarillo.
En un capítulo posterior se hace una revisión sistemática de la especie. Para ello se comparan las únicas poblaciones ibéricas conocidas, Sierra de Cazorla, Bogarra y Riopar. Ningún ejemplar de estas dos últimas presenta los caracteres de niethammeri, por lo que se considera que esta subespecie no es válida y se asimila a marchi. Se incluyen también en este trabajo algunos datos sobre la biología de reproducción de esta especie, desconocidos hasta el momento. La puesta tiene lugar en la primera quincena de julio y consta de 1 a 4 huevos. Las medidas de dos huevos, oompletamente formados en el oviducto eran de 13 x 5,5 Y 10,9 x 6,1 mm. El tamaño de los testículos varía enormemente de primavera a verano. En abril, durante el celo, son 3,7 veces más grandes que en el estío. Finalmente se estudia su ecología. Vive entre los 1.000 y 1.500 m, en las zonas más húmedas de las montañas. Su nicho ecológico corresponde a las asociaciones vegetales Pirno-Juniperion sabinae, Erinacetalia y Quercion pubescentis enclavado en los barrancos muy húmedos. Lacerta hispanica sustituye ecológicamente a Algyroides marchi en las zonas más secas sujetas a fuerte insolación.In this paper the authors study Valverde's lizard, Algyroides marchi, Valverde 1958. The first part refers to the biometry, pholidosis and coloration of the population of Riopar (Sierra de Alcaraz), province of Albacete, obtaining the following results:
Biometry.-The oId males weigh more and have larger heads and limbs than the females. The old females are longer as measured from the end of the snout to the vent. In both sexes the length of the tail 18 is similar.
Pholidosis.-The pholidosis is practically the same in both sexes. The only significant difference is in the number of transverse series of ventral plates, 25,3 in the males and 27,9 in the females.
Coloration.- The males generally present greater pigmentation than the females. There is an elevated proportion of females that maintain the
juvenile coloration.
In a later chapter a systematic revision of the species is made. Three known Iberian populations are compared: Sierra de Cazorla, Riopar and Bogarra. No specimen from Riopar or Bogarra (Sierra de Alcaraz) presented the characteristics of niethammeri, subspecies described by Buchholz (1964). For that reason niethammeri is not considered valid and is asimilated to marchi. So me data on the biology of reproduction have also been included.
The egg-laying takes place during the first two weeks of JuIy and there
are 1-4 eggs. The measurements of two eggs which had been completely formed in the oviduct were 13 x 5,5 mm and 10,9 x 1 mm. The size of the testicles varies greatly from spring to summer. During the copulation period,
in April, the testicles are 3-7 times larger than in the summer. The last chapter studies the ecology of this species. It lives between 1.000 and 1.550 m above sea level, in the most humid mountain zones. lts ecological niche corresponds to the vegetal associations: Pino-Juniperion sabinae, Quercion pubescentis and Erinacetalia. The optimum is the Quercion pubescentis enclaved in very humid ravines. Lacerta hispanica ecologically replaces Algyroides marchi in the dry zones subject to strong solar exposure
Distribución de "Pipistrellus pipistrellus" (Schreber, 1774) y "Pipistrellus Pygmaeus" (Leacha, 1825) (Chiroptera: Vespertilionidae) en la Comunidad Autónoma de La Rioja
This paper deals with the chorology of Pipistrellus pipistrellus (Schreber, 1774) and Pipistrellus pygmaeus (Leach, 1825), two sibling bat species recently segregated in the Autonomous Territory of La Rioja (N Spain). It has been sampled by acoustic methods a total of 141 localities, which covered the 91,3 % of the U.T.M. 10 x 10 km squares of the region. The distribution of P. pipistrellus is wide and continuous in the study area (altitudinal range: 280 - 1.390 m) and this species being one of the most frequent bats in the region. On the contrary, the distribution of P. pygmaeus is very restricted and it seems it only inhabits low-altitude areas of the Ebro valley and of the most oriental mountains of the so-called Northern Iberian System (altitudinal range: 280 - 595 m). This species can be considered also one of the less frequent bats in the region. The identification of the two species has been confirmed by sequenciation of a fragment (734 bp) of the mitochondrial gene cythocrome b in four animals (three P. pipistrellus and one P. pygmaeus).En este trabajo se estudia la corología en la Comunidad Autónoma de La Rioja de Pipistrellus pipistrellus (Schreber, 1774) y Pipistrellus pygmaeus (Leach, 1825), dos especies de murciélagos gemelas recientemente segregadas. Se han muestreado utilizando técnicas acústicas 141 estaciones de escucha que cubren el 91,3 % de las cuadrículas U.T.M. de 10 por 10 km de la región. P. pipistrellus se distribuye de forma amplia y continua por casi toda el área de estudio (rango altitudinal: 280 -1.390 m) y es uno de los murciélagos más frecuentes de la región. P. pygmaeus se distribuye de forma muy localizada, aparentemente sólo en las áreas de baja altitud del valle del río Ebro y las sierras más orientales del sistema Ibérico Septentrional (rango altitudinal: 280 - 595 m), siendo una de las especies menos frecuentes en La Rioja. La identificación de las dos especies se ha confirmado con la secuenciación parcial del gen mitocondrial citocromo b (734 pb) en cuatro individuos (tres P. pipistrellus y un P. pygmaeus)
