Currently considered monotypic, but a second subspecies, cinereiventris, has been described but is not recognized by most taxonomic authorities (25 Dickinson, E. C., and L. Christidis (Eds.) (2014).

L. Wood (2021). The eBird/Clements Checklist of Birds of the World: v2021. Cornell Lab of Ornithology, Ithaca, NY, USA. Close ). It is described as differing from nominate albigula only by having the belly grayer (not white), and the flanks sepia-olive instead of gray (21 Olrog, C. C., and F. Contino (1970). Una nueva subespecie de Grallaria albigula Chapman (Aves, Formicariidae). Neotrópica 16:51–52. Close ). Known from very few specimens, its validity was questioned, albeit without direct examination of material pertaining to cinereiventris by Krabbe and Schulenberg (9 Krabbe, N., and T. S. Schulenberg (2003). Family Formicariidae (ground-antbirds). In Handbook of the Birds of the World. Volume 8: Broadbills to Tapaculos (J. del Hoyo, A. Elliott, and D. A. Christie, Editors).

Molecular phylogenetic analyses show that the White-throated Antpitta appears to be a member of a large and diverse clade of Grallaria antpittas. In a comprehensive phylogeny that includes many Grallaria species that uses ultraconserved element (UCE) markers, Harvey et al. (29 Harvey, M. G., G. A. Bravo, S. Claramunt, A. M. Cuervo, G. E. Derryberry, J. Battilana, G. F. Seeholzer, J. S. McKay, B. C. O'Meara, B. C. Faircloth, S. V. Edwards, J. Pérez-Emán, R. G. Moyle, F. H. Sheldon, A. Aleixo, B. T. Smith, R. T. Chesser, L. F. Silveira, J. Cracraft, R. T. Brumfield, and E. P. Derryberry (2020). The evolution of a tropical biodiversity hotspot. Science 370:1343–1348. Close ) found that the White-throated Antpitta was sister, with strong support, to a large clade that included Watkins's Antpitta (Grallaria watkinsi), Brown-banded Antpitta (Grallaria milleri), Cundinamarca Antpitta (Grallaria kaestneri), Red-and-white Antpitta (Grallaria erythroleuca), Tawny Antpitta (Grallaria quitensis), and White-bellied Antpitta (Grallaria hypoleuca), among others. Together with these species, the White-throated Antpitta was sister to both Pale-billed Antpitta (Grallaria carrikeri) and Chestnut-naped Antpitta (Grallaria nuchalis) (29 Harvey, M. G., G. A. Bravo, S. Claramunt, A. M. Cuervo, G. E. Derryberry, J. Battilana, G. F. Seeholzer, J. S. McKay, B. C. O'Meara, B. C. Faircloth, S. V. Edwards, J. Pérez-Emán, R. G. Moyle, F. H. Sheldon, A.

There are no records of hybridization involving White-throated Antpitta.

Apart from a somewhat controversial subspecies (cinereiventris, see Subspecies), nomenclature and taxonomy of White-throated Antpitta is fairly straightforward. For a summary of pertinent literature, see Scientific Names from the Literature.
