• Phylogenetic placement: Passeri: Passerides: Passerida: Emberizoidea
• Distribution: New World
• Number of extant genera: 30
• Number of extant species: 138

Traditional genus-level classification of extant Passerellidae following the AviList checklist v2025. (link) The number of subspecies is given in parentheses. 

[Notes: (1) The backbone phylogeny is based on Bryson et al., 2016, who included nearly all genera except Amphispizopsis, Centronyx, Oreothraupis, Torreornis, and Xenospiza; (2) The relationships of the remaining genera are based on Klicka et al., 2014, and Barker et al., 2015. (3) The monophyly of Centronyx (ex Ammodramus) needs to be verified, as Barker et al., 2015 found bairdii sister to Xenospiza, and henslowii sister to Passerculus.]
