 The former three are still recognized as subspecies by some, though "M. t. mattogrossensis" is now most frequently recognized not only as a distinct species, but also in a separate genus, "Neoplatymops mattogrossensis".Mammalogist Judith Eger, however, did not recognize any subspecies in "Mammals of South America" (2008).The dwarf dog-faced bat and the rufous dog-faced bat ("M. neglectus") are the only two species in the genus "Molossops".
