Remarks. Emerson (1981) examined the type material of Nirmus rhamphasti and compared it to the type material of Formicaphagus grallariae, which he determined to be a junior synonym of Nirmus rhamphasti . Price et al. (2003: 180) followed Emerson (1981) regarding Nirmus rhamphasti as a valid species of Formicaphagus and listed F. grallariae as a junior synonym of the former. Mey & Barker (2014: 93, 100) argued that Nirmus rhamphasti Carriker 1903 should be placed in Sturnidoecus . We have not examined any material of this species, but include it here because it has been associated by various authors with genera we recognized as belonging to the Brueelia - complex.
