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".

White-fronted Ground Tyrant
Muscisaxicola albifrons
The white-fronted ground tyrant is the largest member of its genus at 21.5 to 24 cm (8.5 to 9.4 in) long. The sexes have the same plumage. Adults have a white forehead ("front") that extends rearward in a "vee" above the eyes and a warm grayish brown crown on an otherwise blackish face. Their nape and back are brownish gray. Their wings are dark brown with wide white edges on the secondaries that show as a panel on the wing. Their tail is dark brown with grayish white edges on the outer feathers. Voice: As of April 2025 xeno-canto had only one recording each of the white-fronted ground tyrant's song and call. The Cornell Lab of Ornithology's Macaulay Library had the same call recording and five others also of calls. The song has not been described; the call is described as "a soft series of notes tip-tip-tip...".
