“…The range of O. hatti includes northeastern Guatemala, central and northern Belize, and most of the Mexican states of Campeche, Yucatan, and Quintana Roo Hall 1981). O. hatti mouse has been recorded at only 10 localities: Chichén-Itzá , Yucatan; Calakmul, Conhuá s, Escá rcega region, and Dzibalchén, Campeche; Rancho Las Palmas and Reserva Ecoló gica El Edén, Quintana Roo; Cayo District and Rockstone Pond, Belize; and Tikal, Guatemala (Anthony 1932;Aranda et al 1997;Genoways et al 2005;Herná ndez-Huerta et al 2000;Jones et al 1974;Laurie 1953;Peterson 1966;Rick 1965;Vargas-Contreras et al 2004). Elevational range of known localities is sea level to 250 m.…”

“…External measurements (means, ranges in parentheses, in mm or g) of 9-14 adult individuals of both sexes were: total length, 201.9 (163-231); length of body and head, 100.6 (90-116); length of tail, 102.6 (60-127); length of hind foot, 21.3 (18-23); length of ear, 15.0 (13-20); and body mass, 29.0 (23-36-Anthony 1932; Aranda et al 1997;Genoways et al 2005;Herná ndez-Huerta et al 2000;Jones et al 1974;Peterson 1966;Rick 1965;Vargas-Contreras et al 2004).

“…Otonyctomys hatti occurs in mature semideciduous tropical forests that are relatively open (Aranda et al 1997;Genoways et al 2005;Herná ndez-Huerta et al 2000;Vargas-Contreras et al 2004), and vegetation near cenotes (water-filled sinkholes- Jones et al 1974). In Belize, vesper mice were restricted to the broad-leafed forests of the northern plains and watersheds of rivers (McCarthy 1998).…”

“…It has been trapped on dead logs , in trees (Herná ndez- Huerta et al 2000;Jones et al 1974), on lianas (Peterson 1966), and from the top of a coconut palm (Peterson 1966), usually at 1-2 m from the ground. In Reserva de la Biofera Ria Lagartos, Yucatan, 1 individual was observed in June 2005 using an abandoned nest of a woodpecker in a dead tree at 1.8 m from the ground (J. Chablé, pers.…”

Nuevas localidades en la distribución de murciélagos filostóminos (Chiroptera: Phyllostomidae) en Chiapas, México.

“…procerum, E. pittieri, S. donell-smithii, X. flexuosa, S. saponaria, L. candida, L. schiedeanus y B. simaruba. En México ha sido registrada en los estados de Campeche, Chiapas y Veracruz (Navarro, 1979;Lopez et al, 1998;Hernández-Huerta et al, 2000;Escalona-Segura et al, 2002). Nuestro registro confirma la distribución potencial de la especie en Chiapas (Hernández-Mijangos et al, 2008), de la que se especulaba que abarcaba las selvas de la zona norte del Estado que se conectan con Veracruz (Medellín et al, 1997).…”
