● "Aimophila² ruficeps sororia. LAGUNA SPARROW.  ... ² I am at present unable to discover any characters sufficient to separate Peucæa from Aimophila, unless the former be restricted to P. æstivalis, P. botteri, and P. cassini. Aimophila ruficeps is connected with the type (A. ruficauda) by such intermediate species as A. mcleodi, which Mr. Brewster described as an Aimophila and Messrs. Salvin and Godman as a Peucæa (P. megarhyncha)" (Ridgway 1898) (subsp. Aimophila ruficeps).
● "♂ mari M. gutturalis, Scl. et Salv., simillimus  ... Peut-être la M. sororia est-elle encore plus proche de la M. spodionota, Scl. et Salv., de l'Équateur oriental, ou même identique" (von Berlepsch & Sztolcman 1894) (subsp. Epinecrophylla spodionota).
● "G. G. regulo dicta cui forma similis affinis" (von Berlepsch & Sztolcman 1901) (subsp. Grallaria guatimalensis).
● "Similar to H. f. aurigularis ... but males with throat paler yellow" (Zimmer 1947) (subsp. Hemithraupis flavicollis).
● "This is a northern representative of L. nematura of the wood-region of Brazil, and is closely allied to that species" (P. Sclater & Salvin 1873) (subsp. Lochmias nematura).
● "Much like M. m. melanolaema [= syn. Myrmoborus myotherinus] Scl. ... but averaging smaller" (Hellmayr 1910) (subsp. Myrmoborus myotherinus).
● "The Sphenocercus I should like to stand as S. sororius, from its close affinity to S. sieboldii" (Swinhoe 1866) (subsp. Treron sieboldii).
