Adenogramma littoralis

Scientific Name
Adenogramma littoralis Adamson
Higher Classification
National Status
Status and Criteria
Data Deficient - Insufficient Information
Assessment Date
L. von Staden
A widespread, but very poorly known species (EOO 16 344 km²). It is possibly threatened by habitat loss and degradation, but due to a lack of recent field observations nothing is known about its population size, structure and trends. Therefore its risk of extinction cannot be assessed at present.
South African endemic
Provincial distribution
Northern Cape, Western Cape
Coastal areas from Hondeklipbaai in Namaqualand to False Bay.
Habitat and Ecology
Major system
Major habitats
Namaqualand Coastal Duneveld, Overberg Dune Strandveld, Namaqualand Strandveld
Deep sands at low altitudes, often near the sea.
The threats to this taxon are not known. It is probably threatened by habitat loss to mining on the Namaqualand coast, where extensive, highly destructive open-cast mining has led to the loss and degradation of large areas of coastal duneveld. Further south it is likely to be threatened by habitat loss to coastal development.

This species is known from only a handful of historical records, and was last observed in 1952. Adenogramma species are cryptic and very easily overlooked, but the lack of recent records are concerning. Field surveys are needed to relocate it in the wild. Historical records suggest that it has a fairly wide distribution range, but based on available data, the number of extant subpopulations, population size and trends cannot be estimated.

Population trend
This species has not been recorded from any formally protected areas.
