Race barlowi (with patae and cavei) commonly split as a separate species, but genetic differences minor#R, vocal differences tiny or non-existent, and published statistical differences in size#R driven by inclusion of C. albescens in tests (no differences when albescens excluded). Four subspecies recognized.

Subspecies and Distribution
  • C. e. erythrochlamys (Strickland, 1853) – Dune Lark – WC Namibia, between R Kuiseb (Walvis Bay) and R Koichab (Lüderitz).
  • C. e. barlowi (Roberts, 1937) – Barlow's Lark – SW Namibia from S of R Koichab (inland of Lüderitz) E to Aus.
  • C. e. patae (Macdonald, 1953) – coastal sands from SW Namibia (Lüderitz) to extreme NW South Africa (Port Nolloth).
  • C. e. cavei (Macdonald, 1953) – inland part of coastal plain from extreme SW Namibia (S from Aus) to NW South Africa (R Holgat).
