This molossid bat has disjunct records in Central America and northwestern South America. A 2020 genetic study separated the northern lineage previously included in M. currentium as M. bondae and used differences in dorsal fur and upper incisors to diagnose it.
The 2020 diagnosis describes a medium-sized Molossus with dorsal fur from coffee brown to blackish. A pale hair base is absent or no longer than one-third of the hair; dorsal hairs average about 4.0 mm. Mean forearm length in the study specimens was 42.0 mm in males (39.0–44.1 mm) and 41.6 mm in females (40.4–43.7 mm). The upper incisors are spatulate with convergent tips.
A 2001 species account reports roosts in buildings and a second-story porch roof in Costa Rica, a church in Nicaragua, and a house in Panama. These are historical Central American observations. Southern South American populations formerly treated under the same name are now separated, and their records are excluded here.
An extinction-risk assessment has not been added yet.
