Ryan, P. G.; Bloomer, P. 1999. The Long-billed Lark complex: a species mosaic in southwestern Africa. The Auk 116: 194-208.
Certhilauda curvirostris (Sibley and Monroe 1990, 1993) has been split into C. curvirostris (including brevirostris), C. subcoronata (including damarensis and benguelensis) and C. semitorquata by the BirdLife Taxonomic Working Group following review of museum material and the arguments presented in Ryan and Bloomer (1999). Ryan and Bloomer (1999), in addition to splitting curvirostris, subcoronata and semitorquata, propose elevating brevirostris and benguelensis to species level, but this treatment, based largely on genetic evidence, is not supported by morphological and vocal evidence from museum specimens and scientific and popular literature; there is evident ambiguity in the placement of subspecies and differences between them are slight.
