Subspecies
Genus often merged with Hirundo, but DNA studies support retention of separate taxa. Forms a superspecies with Pale Sand Martin (Riparia diluta) and often regarded as conspecific, but cytochrome b evidence supports treatment as separate species. Subspecies aequatorialis sometimes referred to by new name chapmani, which was proposed in mistaken belief that former name preoccupied.
The following 2 subspecies are recognised:
aequatorialis Chapman, 1924 - South-western Ecuador (Manabí south to El Oro and western Loja).
rufocollaris Peale, 1848 - Western Peru (south to Lima).
