A new Lophostoma (Chiroptera: Phyllostomidae: Phyllostominae) from the Amazonia of Ecuador

Resumen

We describe a new species of phyllostomid bat, genus Lophostoma, from eastern Ecuador.Lophostoma yasuni n. sp.resembles L. carrikeri for its white ven¬ ter and L shulzi in size, but it is distinguishable from both by external and cranial characteristics.Lophostoma yasuni has a shorter forearm than the average expected for L. carrikeri; however the skull is the largest in relation to L. carrikeri and L. shulzi.L. yasuni does not present the wart-like granulations on the forearms characteristic of L shulzi. ResumenDescribimos una nueva especie de murcielago filostomido del genero Lophostoma del este de Ecua¬ dor.Lophostoma yasuni n. sp.es similar a L. carrikeri por su vientre bianco y a L shulzi en tamano, pero es distinguible de las dos por caracteristieas externas y As currently recognized, the genus Lophostoma comprises six species: L. aequatorialis Baker et al. 2004, L brasiliense (Peters 1866), L carrikeri (Allen 1910), L. evotis (Davis and Carter 1978), L schulzi (Genoways and Williams 1980, and L. silvicolum d'Orbigny 1836.During a survey of mammals in the Yasuni National Park and Biosphere Reserve in Ecua¬ dor (Fig. 1), wre collected a specimen of Lophostoma externally similar to L. carrikeri.Further comparisons, however, revealed striking size and cranial morphol¬ ogy differences distinguishing the specimen from L. craniales.Lophostoma yasuni tiene el antebrazo mas corto que el promedio esperado para L. carrikeri; pero el craneo es mas grande en relacion a L. carrikeri y L. shulzi.Ademas, L. yasuni careee de las granulaciones en los antebrazos que caracterizan a L shulzi.carrikeri, and all other described species of Lophostoma.Its unique morphology indicates that this specimen represents an undescribed species that we
