|Scientific Name:||Afrixalus spinifrons|
|Species Authority:||(Cope, 1862)|
|Taxonomic Notes:||We follow Pickersgill (1996) in considering what were formerly regarded as the eastern populations of Afrixalus knysnae to be a subspecies of A. spinifrons (A. s. intermedius). Species boundaries in this complex are uncertain and taxonomic studies using calls, morphology and genetics are necessary.|

Listed as Near Threatened as although its extent of occurrence is 19,000 km², its area of occupancy is less than 1,900 km², and there is continuing decline in the quality of its habitat, there are 11 locations and the spatial distribution of this species is not considered to be severely fragmented. However, certain sites where this species occurs do have a large number of different threats which may seriously impact on population viability in future. Loss of certain sites could easily result in less than 10 locations triggering the criteria for Vulnerable status.
|Range Description:||This species, which is endemic to South Africa, occurs as two subspecies: A. s. spinifrons occurs in the KwaZulu-Natal lowlands, and eastern Cape coast of South Africa at low to intermediate altitudes; A.s. intermedius occurs at altitudes above 1,000 m to around 1,500 m asl in western KwaZulu-Natal between the midlands and foothills of the Drakensberg. The Extent of Occurrence is around 19,000 km², and the Area of Occupancy is estimated to be 10% of this.|

|Population:||This species is hard to detect but it is known to be doing well at some sites where it appears abundant.|
|Habitat and Ecology:||It is associated with low vegetation in shrubland and dry forest. It breeds in vleis (including dams) and temporary pools and pans (including roadside pools) and uses emergent vegetation to create egg nests. Species in this genus deposit between 20 and 50 eggs on vegetation above the water. Tadpoles emerge, drop into the water and remain there until metamorphosis.|
|Use and Trade:||
There are no reports of this species being utilized.
Certain subpopulations are affected by loss of wetlands through urban and recreational development, afforestation, agricultural expansion, pesticides, and overgrazing by livestock. Coastal populations (i.e. A. s. spinifrons) may be at higher risk than those inland due to heavier development pressure along the KZN coastline.
Determining whether the two subspecies are separate species is a high conservation research priority for this species, and the entire genus in
Afrixalus spinifrons intermedius occurs in the
