Sasia is a genus of birds in the family Picidae, that are native to the Old World. They are very small, virtually tailless woodpeckers, with a crombec or nuthatch-like appearance and foraging habits. Their habitat is forest and secondary growth.[1]

All three species have a flesh orbital ring and a rounded (in cross-section) upper mandible.[2] The African species has only eight rectrices but four toes in a zygodactyl arrangement (a weak first digit), while the two Asian species have ten rectrices and only three toes (absent first digit, or hallux).[2] In addition the African species differs from the Asian species in plumage colour of the adult, but not at all in plumage pattern, body anatomy or in habits.[3]

Their relationship with genus Picumnus has not been established, and the Picumninae may be either monophyletic[4] or paraphyletic.[5]

It contains the following species:

African piculet (Sasia africana) – moist African tropics
Rufous piculet (Sasia abnormis) – mainly Malaysia and Indonesia
White-browed piculet (Sasia ochracea) – mainland Southeast Asia
