This species is listed as Vulnerable because it is estimated that fewer than 10,000 mature individuals remain and it is projected that the population will decline by at least 10% in the next three generations (where generation length is five to six years; Pacifici et al. 2013) based on habitat loss.

Geographic Range [top]

Range Description:

This species is known from Jalisco, Colima, Michoacan, Guerrero, Morelos and Puebla in Mexico (Ceballos and Oliva 2005, Orozco-Lugo et al. 2013). The maximum altitudinal record for the species is over 1,700 m asl (Alvarez-Castañeda and Lopez-Forment 1995, Tellez and Ortega 1999).

Population [top]

Population:This bat species was poorly studied until a few years ago, but the German-Mexican team as part of the Program for Mexican Bat Conservation (PCMM) has carried out new studies. It is considered an uncommon species (Arroyo-Cabrales pers. comm.). They roost in small groups. Currently they are considered as residents at the localities where they have been collected (Tschapka et al. 2008). They do not hibernate (Bergstresser 2002).
Current Population Trend:Decreasing
Additional data:
Number of mature individuals:10000Continuing decline of mature individuals:Yes
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Apparently, its occurrence is restricted to the arid thorn and tropical deciduous forest along the Pacific versant. These habitats have a clear summer rainy season (from July to October) and a remarkably dry season (from November to May). During this last period the majority of the trees lose their leaves. The dominant species in these habitats are Cordia alliodora, Caesalpina eriostachys, Lysiloma divaricata, Brosimun alicastrum and Tabebuia donnell-smithi. This species has been found roosting in a sheltered, but not secluded, rocky overhang above a stream in a canyon. In addition, this bat was found roosting in a culvert and in a cave. Reproductive records are limited. Two pregnant females were collected in Colima in September. A female captured in August was lactating (Tellez and Ortega 1999). It has a generation length of five to six years (Pacifici et al. 2013).
Generation Length (years):5-6

Use and Trade [top]

Use and Trade: This species is not used.

Threats [top]

Major Threat(s): Habitat loss, caused by changes in land use for agriculture and also by fires, is the primary threat (Arroyo Cabrales pers. comm.).

Conservation Actions [top]

Conservation Actions: This species is including inside the Mexican regulation for species conservation NOM-59-SEMARNAT-2001 (under P category which means Endangered of extinction). It is found in several protected areas (Cuenca de los Rios Valle de Bravo, Malacatepec, Tilostoc y Temascaltepec; Chamela-Cuixmala Reserve; Zicuiran-Infiernillo Biosphere Reserve). The protection of this species is being undertaken by the Program for Mexican Bat Conservation (PCMM; Arroyo-Cabrales pers. comm.).
