This species was previously part of the Hipposideros ruber complex. However, Vallo et al. (2008) have somewhat clarified the taxonomy of this group and show that H. cafer s.s. is restricted to southern African. The northern limits of this species are currently unknown and may include Tanzania and Kenya (Vallo et al. 2008, Monadjem et al. 2013).

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.

The exact range of this species is not currently known. Hipposideros caffer sensu lato occurs across most of sub-Saharan Africa except for central forested regions as well as in parts of Arabia (Simmons 2005). However, H. caffer s.s. is only known from southern African countries of Botswana, Mozambique, South Africa, Eswatini, Zimbabwe. Populations in Malawi, Zambia, and southern Tanzania may refer to this species, while the taxonomic status of East African records is currently unresolved. Elevation ranges from sea level to 2,500 m in this area.

A widely distributed and numerous species. Sundevall's leaf-nosed bats are extremely gregarious and capable of forming huge colonies where there is adequate roosting space (Monadjem et al. 2010). This species also has been found roosting in sinkholes and cavities, including human-made structures, e.g. mines and culverts (Cotterill 2001).

This species occurs in savanna, bushveld and coastal forest, and is usually associated with rivers and other water resources (Taylor 2000), provided there are caves or buildings where it can roost during the day (Happold 1987). Colony size varies from small to medium-sized groups of tens or hundreds of individuals (Taylor 2000), exceptionally up to 500,000 (Brosset 1966; Happold 1987).

Human disturbance to roosting sites (caves) could have a negative effect.

No specific conservation measures in place. Occurs in protected areas throughout its range.
