The micro frog (Microbatrachella capensis) is a minute species of frog in the Pyxicephalidae family, in the monotypic genus Microbatrachella. At around 18 mm (0.71 in) long, it is one of the smallest regional species. Its colour varies from rufous brown with dark mottling, to tan or green, depending on the population.
This species occurs only in the coastal lowlands (from 15 m up to 80 m asl) in the south-western part of Western Cape province, South Africa, where it formerly ranged from Cape Town east to the Agulhas Plain (with an extent of occurrence of 1,399 km). However, it is now extinct on the Cape Flats near Cape Town, except at one locality at Kenilworth Race Course. Its eastern distribution is much more fragmented than is shown on the map (four locations), since it occurs only in very isolated localities (area of occupancy 7.36 km, which is considered to be declining).
