Cinereous Ground Tyrant
Muscisaxicola cinereus
The cinereous ground tyrant is 15.5 to 16.5 cm (6.1 to 6.5 in) long. The two subspecies and the sexes have the same shades of gray plumage ("cinereous" means ash-colored). Subspecies M. c. argentinus is slighter larger than the nominate. Adults have a grayish brown crown, dusky lores, and a thin white supercilium to above the eye. Their nape and back are grayish brown. Their wings are a duskier grayish brown with some paler edges on the coverts. Their tail is blackish with thin white edges on the outermost feathers. Their underparts are mostly grayish white with a somewhat whiter belly. Voice: As of April 2025 xeno-canto had only one recording of a cinereous ground tyrant vocalization; the Cornell Lab of Ornithology's Macaulay Library had seven including the xeno-canto one. Its song has not been described; its call is "a soft pip repeated at intervals".

Puna Ground Tyrant
Muscisaxicola juninensis
The puna ground tyrant is 16 to 16.5 cm (6.3 to 6.5 in) long. The sexes have the same plumage. Adults have a dull cinnamon crown, a white spot above their lores, a faint pale supercilium, and a pale broken eye-ring on an otherwise pale brownish gray face. Their upperparts are mostly pale brownish gray with a black lower rump. Their wings are dusky gray. Their tail is black with white edges on the outer webs of the outermost feathers. Their throat and belly are whitish and their breast pale gray. They have a dark iris, a black bill, and black legs and feet. Voice: As of April 2025 xeno-canto had a single recording of a puna ground tyrant vocalization and the Cornell Lab of Ornithology's Macaulay Library had five others. The species' song is not known. Its call is "a soft high-pitched peep repeated at intervals".
