|Scientific Name:||Molossus rufus|
|Species Authority:||É. Geoffroy, 1805|
Molossus ater É. Geoffroy, 1805 [incorrect use of name]
|Taxonomic Notes:||Called ater by many authors, but see Dolan (1989), who argued, based on descriptions of head and ear shape of both taxa, and examination of the specimens labeled as types of rufus in the Muséum National d’Histoire Naturelle in Paris, that Molossus ater Geoffroy, 1805, is really an Eumops, and that rufus is really the correct name for the large Molossus often incorrectly called ater. Species requires taxonomic revision and studies (Barquez pers. comm.).|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor(s):||Barquez, R., Rodriguez, B., Miller, B. & Diaz, M.|
|Reviewer(s):||Medellín, R. (Chiroptera Red List Authority) & Schipper, J. (Global Mammal Assessment Team)|
This species is listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.

|Population:||In a study carried out in Rio de Janeiro state, Brazil, found that the colonies in this species can exceed more than five hundred, being present both sexes. Between April to July the proportion of males overcome the females, while in other months the females prevailed. M. rufus have seasonal reproduction. Females arrived by July and the number increases until November. Pregnant females were captured between September, October, November and February. Lactating females were observed in August, October, November, December and February. Active males were observed in all months, being overcome by males with abdominal testes only in July (Esberard 2002).|
|Current Population Trend:||Stable|
|Habitat and Ecology:||Roosts in buildings, hardly captured outside the roosts. Found in tropical deciduous forests, evergreen, shrubs, oak forest and secondary vegetation(Santos and Castro-Arellano, 2005).|
|Major Threat(s):||None known.|
|Conservation Actions:||Found in protected areas. Needs taxonomic review.|
