Micropus bradfieldi

Roberts

, 1926,

Namibia

.

Formerly considered conspecific with Tachymarptis aequatorialis, and resemblance between the two suggested to be more than superficial. However, recent molecular phylogeny#R placed this species in a clade with A. niansae, A. barbatus, A. berliozi, A. unicolor, A. alexandri, A. pallidus and A. apus. Has been thought to be closest to A. barbatus, A. berliozi and A. pallidus. Two subspecies recognized.

Subspecies and Distribution
  • A. b. bradfieldi (Roberts, 1926) – SW Angola and Namibia.
