Amietia wittei, also known as the Molo frog or De Witte's river frog, is a species of frog found in the montane grasslands of Kenya and Tanzania. This species is distinctive for its dark brown dorsal coloration, which lightens on the flanks and becomes yellowish on the belly, and for the black dorsolateral folds that extend to the groin.

Key Facts

  • Found in Kenya and Tanzania, including Mount Elgon.
  • Inhabits montane grasslands at elevations between 1,100–3,300 meters.
  • Adult females are larger than males, reaching up to 87 MM in snout-urostyle length.
  • Characterized by dark brown dorsal coloring and black dorsolateral folds.
  • Associated with streams and can be found in areas of low-intensity agriculture.

Description
Amietia wittei exhibits sexual dimorphism, with adult males reaching approximately 55 mm and adult females growing up to 87 mm in snout-urostyle length. The frog's dorsal coloration is a dark brown, which fades to a lighter shade on its flanks and turns yellowish on its belly. Distinctive features include black dorsolateral folds and numerous elongated warts on its back. A line of irregular dark blotches extends from the groin towards the tympanum. Some individuals display a pale, bright green vertebral stripe. The upper lip is uniformly dark or marbled, and a pale, coppery band above the lip runs between the tympanum and the eye, often touching it. The lower lip is typically marbled.
Habitat Description
This species is found in montane grasslands at elevations ranging from 1,100 to 3,300 meters (3,600 to 10,800 feet) above sea level. Amietia wittei is closely associated with streams and can be observed in landscapes influenced by low-intensity agriculture. It is also present within several protected areas, including Aberdare and Mount Kenya National Parks in Kenya, Mount Elgon National Park on the Kenya/Uganda border, and Kilimanjaro National Park in Tanzania.

About Amietia wittei

Amietia wittei: The Molo Frog

Amietia wittei, commonly known as the Molo frog or De Witte's river frog, is a species of frog belonging to the family Pyxicephalidae. This amphibian is native to Kenya and Tanzania, with its distribution extending to areas such as Mount Elgon on the Kenya-Uganda border. The species' type locality is Molo, Kenya, situated near the summit of the Mau Escarpment. The specific epithet 'wittei' serves to honor Gaston-François de Witte, a notable Belgian naturalist.

Description and Habitat

Amietia wittei is characterized by its distinct coloration and size. Adult males typically measure up to 55 mm, while females are larger, reaching up to 87 mm in snout-urostyle length. The frog's dorsal surface is dark brown, gradually lightening on its flanks and becoming yellowish on the ventral side. Prominent black dorsolateral folds run along its body, accompanied by numerous elongated warts on its back. Some individuals may also feature a pale, bright green vertebral stripe. The upper lip is uniformly dark or marbled, with a pale, coppery band above it that stretches between the tympanum and the eye. The lower lip is often marbled.

This species thrives in montane grasslands at considerable altitudes, typically between 1,100 and 3,300 meters above sea level. Amietia wittei is closely associated with streams and can also be found in environments modified by low-intensity agriculture. Its presence is noted within several national parks, including Aberdare and Mount Kenya National Parks in Kenya, Mount Elgon National Park, and Kilimanjaro National Park in Tanzania.

Conservation Concerns

Despite being locally common, Amietia wittei faces significant threats due to habitat loss and degradation. These pressures stem from the expansion of human settlements, increased demand for wood collection, and logging activities within its natural range. These factors contribute to a deterioration of the frog's essential habitats.
