    Abstract
    We describe a new species of small-eared shrew, Cryptotis hondurensis (Insectivora: Soricidae), from high elevation pine forest on the western slope of Cerro Uyuca, Francisco Morazán Province, southcentral Honduras. The new shrew is most similar in outward appearance to C. gracilis, from which it can be distinguished by cranial and dental features, particularly a shorter, broader mandible with a coronoid process that meets the ramus at nearly a right angle and an m3 with a simple talonid. Cranially, the new species is most similar to C. nigrescens merriami, but differs from this species in its longer tail and several cranial and dental features, inc1uding a more complex M3. The holotype of the new species had been identified as C. gracilis and represented the only specimen of that species north of Costa Rica. Its recognition as a distinct species removes C. gracilis from the known fauna of Honduras. The other species of Cryptotis presently known from Honduras are C. nigrescens merriami and C. parva orophila.
     
    Resumen.--Se describe una nueva especie de musaraña, Cryptotis hondurensis (Insectivora: Soricidae), del bosque montanoso de la ladera occidental del Cerro Uyuca, Francisco Morazán, Honduras. Externamente, la nueva especie es similar a C. gracilis pero se diferencia de C. gracilis en características craniales y dentales; en particular, en la presencia de una mandíbula mas corta y mas ancha y con un proceso coronoides que se junta con la rama mandibular en un ángulo de casi 90 grados. Además, m3 presenta una talonida simple. El cráneo de la nueva musaraña se semejante al de C. nigrescens merriami pero la nueve especie defiere de C. nigrescens merriami por su cola mas larga y en varias características craniales y dentales incluyendo M3 con una corona mas compleja. El holotipo de la nueva especie había sido identificado como C. gracilis y este especimen era el único representante de esta especie al norte de Costa Rica. El reconocimiento de este especimen como una especie distinta, limita la distribución de C. gracilis a Costa Rica y Panamá y la remueve de la fauna de Honduras. Las otras especies de Cryptotis que habitan en Honduras son C. nigrescens merriami y C. parva orophila.
