Despite its relatively tiny range, in southern Venezuela and immediately adjacent parts of northernmost Brazil and westernmost Guyana, four subspecies of the Tepui Antpitta are recognised, although they appear to differ rather little in plumage and apparently not at all in their vocalizations. Also known as the Brown-breasted Antpitta, the species’ overall plumage is dark chestnut-brown above, with a pale postocular spot, a white throat and generally greyish or brown underparts. Its nest is apparently similar, in being cup-shaped and placed low off the ground, to congenerics, and the clutch size is also two eggs. Like other Myrmothera antpittas, the species forages alone and typically on the ground, in the dense undergrowth of forest between 600 and 2400 m.
