Pseudammomanes barlowi

Roberts

, 1937,

8 miles [c. 13 km] west of Aus, Namibia

.

Forms a superspecies with C. burra, C. albescens and C. erythrochlamys; sister-species to last of those, with no known range overlap between the two. Recently split from C. albescens on grounds of genetic, morphological and vocal evidence; hybridizes with it in S of range (narrow zone between R Orange and Port Nolloth). Geographical variation linked to soil type (pale sands on coast, redder inland); differentiation marked in SW of range, with coastal patae replaced by inland cavei over distance of just a few kilometres and intermediates scarce; nominate intergrades with latter race. Three subspecies recognized.
