Except for largely migratory species (such as nectar-feeding phyllostomids), most members of the Neotropical families Phyllostomidae, Mormoopidae, Emballonuridae
, and Natalidae reach their northwestern limits in Mexico at about the lower Rio Yaqui, or along the lower rios Mayo and Fuerte, and help define the Neotropical-Nearctic boundary (Anderson, 1960; Koopman, 1961; Findley and Jones, 1965).
Bat CoVs are typically host specific; however, MERS-related CoVs have reportedly been found in many bat families, including Vespertillionidae, Molosidae, Nyteridae, and now Emballonuridae
(sheath-tailed bats) in Africa, the Americas, Asia, and Europe.
Within the Chiroptera, secondary sexual dimorphism is primarily limited to size, although other characteristics, such as dimorphic glands, are not uncommon in the Emballonuridae
and Molossidae (Bradbury, 1977).
