Description
Diagnosis: Nectophyrnoides vestergaardi can be distinguished from N. tornieri by its rounded toes and fingers that lack truncated ends. It can be differentiated from some of the species in its genus by the presence of a distinct tympanum, narrow and elongated paratoid glands, the lack of glands on the limbs, and the shape of the body and head (Menegon et al. 2004).

Description: N. vestergaardi has short, slender limbs. The tympanum is easily seen. Raised parotid glands are present that are equally as long as wide and also have dark edges. Toes and fingertips can be rounded or pointed. The fingers are only slightly webbed and toes are partially webbed (Menegon, et al. 2004).

Coloration: The dorsal side is light with the lateral sides being darker. Many individuals have a dark stripe running down the dorsum (Menegon et al. 2004).

Coloration in Preservative: In preservative, the dorsal ground color is light brown, and the lateral sides darker. The ventral side is pale cream, and the ventral side of the chin is cream (Menegon, et al. 2004).

Variation: There is little variation in the dorsal pattern among individuals or between sexes. The dorsal skin does show some variation between smooth and rough (Menegon et al. 2004).

This species is found in the West Usambara Mountains in northeastern Tanzania, at an altitude of 1230-2000 m. Its habitat is in submontane and montane forest, the ecotone between forest and ericaceous vegetation (Menegon and Loader 2004).

Life History, Abundance, Activity, and Special Behaviors
No call has been recorded. N. vestergaardi hides in rotten logs.

It is presumed to have internal fertilization and direct development like other species in its genus (Menegon and Loader 2004; Orton 1949).

Trends and Threats
The species population is declining, but it is protected in a forest reserve by Dar es Salaam University. Deforestation and urbanization are threatening its habitat. It is listed as endangered, partly due to the decline in the quality of its habitat (Menegon and Loader 2004).

Relation to Humans
N. vestergaardi is used as a biological resource (Menegon et al. 2004).

Possible reasons for amphibian decline

General habitat alteration and loss
Habitat modification from deforestation, or logging related activities
Urbanization

Comments
The species authorities are M. Menegon, S. Salvidio, and S.P. Loader. N. vestergaardi was named for Martin Vestergaard, a Danish zoologist, who first discovered it.
