The Sinaloa mastiff bat is the largest species of the genus known 

 to occur in Panama. It is similar to Molossus bondae, but larger and 

 somewhat lighter in color, the upperparts being a dark brownish 

 drab. The forearm measures about 47 millimeters. 



The range of the species, as now understood, is from Sinaloa, 

 Mexico, southward through Middle America to western Panama.
