This species occurs in coastal Kenya and eastern Tanzania, including Zanzibar and Songo Songo Islands, ranging from Gede in the north, south to the Rondo Plateau. In Kenya, this species occurs only close to the coast, but in Tanzania it ranges inland as far as Kilosa and the Kihanis Gorge in the Udzungwa Mountains. It is generally a low-altitude species occurring up to 800 m asl.
Habitat and Ecology
It is a species of lowland forest, dense woodland, thicket, and the forest-miombo woodland boundary. It survives in modified secondary habitats with good cover. It breeds by internal fertilization, laying eggs in small water-filled holes and crevices (including snail-shells), where the larvae develop.
It is regularly encountered, but it is a difficult species to detect, and so it might be more common than is generally supposed.
It is probably affected by the loss of its habitat for agriculture, wood extraction and human settlement.
It occurs in the Arabuko-Sokoke Nature Reserve (Kenya), the Shimba Hills National Park (Kenya). It potentially occurs in the Selous Game Reserve and Mikumi National Park (both in Tanzania) but it has not yet been recorded in these places.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its relatively wide distribution and its presumed large population.
