Distribution

B. sopranus is found in South Africa, Swaziland and Lesotho and may also occur in southern Mozambique (Passmore and Carruthers, 1995; Minter 1998, 2003; Text from Minter et al., 2004, © SI/MAB Biodiversity Program).

Morphology

The males of B. sopranus range from 22–26.2 mm (N = 14) in body length. This species is morphology similar to B. mossambicus and B. bagginsi (Text from Minter et al., 2004, © SI/MAB Biodiversity Program).

Habitat and Ecology

B. sopranus inhabits a variety of vegetation types within the Forest and Savanna biomes: it is found in the dense, herbaceous undercover (Text from Minter et al., 2004, © SI/MAB Biodiversity Program).

Advertisement Call

The unusual call may easily be mistaken for that of an insect or bird, particularly when heard during the day. Choruses develop at any time of day, during light to heavy rain, but unless this is followed by drizzle or heavy mist, cease immediately afterward. Minter (1998, 2003) found that calling males often take up elevated positions on fallen branches or small plants, or call from the soil surface (Text from Minter et al., 2004, © SI/MAB Biodiversity Program).

Minter (2003) report that morphologically, the species is difficult to separate from B. mossambicus and B. bagginsi, but can be easily distinguished from all Breviceps species by it’s advertisement call, a series of long, unpulsed, high-pitched whistles. Each calls varies from 0.6–1.98 s in duration and from 2755–3468 Hz in frequency (Text from Minter et al., 2004, © SI/MAB Biodiversity Program).

IUCN Red List Category and Justification of Conservation Status

B. sopranus is a recently described species (Minter 2003). Since the distribution and biology of this species are poorly known, an accurate assessment of its conservation status is not possible at present. It is therefore assigned to the category “Data Deficient” (Text from Minter et al., 2004, © SI/MAB Biodiversity Program).

Threats

Outside of these protected areas much of the natural habitat of this species has been destroyed by the farming of crops such as sugarcane, and by deforestation in the Dukuduku forest (Text from Minter et al., 2004, © SI/MAB Biodiversity Program).

Conservation Actions and Management

Distribution, life history and ecological data are urgently needed in order to adequately address the conservation needs of this species (Text from Minter et al., 2004, © SI/MAB Biodiversity Program).
