Strongylopus Tschudi, 1838
Adult snout to vent lengths are typically in the range of 25 to 53 millimetres. Some of the species are documented to have a pronounced sexual dimorphism, with female lengths exceeding male lengths by approximately thirty percent, e.g. S. fuelleborni (Harper et al. 2010).
Species within the genus Strongylopus are generally restricted to southern and eastern Africa, with countries of occurrence including South Africa, Lesotho, Swaziland, Mozambique, Malawi, Zambia, Zimbabwe, Tanzania and Kenya. Elevations of occurrence are limited from sea level to 3250 metres. Three of the species are endemic to high altitude niches in Tanzania, and two of the species are endemic to South Africa. Most of the taxa within the genus are restricted to very narrow geographic ranges.
Species of the genus Strongylopus are found in a number of riparian habitats, including fynbos heath, grassland, montane flooded grassland, savanna and forest edge. Generally the stream margins proximate to terrestrial habitats are richly vegetated. More specialised habitats are seen in some of the highly restricted range taxa; for example, Strongylopus kilimanjaro is found in alpine moorland near cold water streams (Stuart, 2006)
