In 1870, he created a new genus, Oncophorus with the same type species,[3] making it an objective junior synonym of Trabeculus.

[6][7] Thomas Harvey Johnston and Launcelot Harrison created a new genus name, Rallicola, in 1911.

[7] This referred to a species Christian Ludwig Nitzsch named Philopterus (Nirmus) attenuatus,[12] which Édouard Piaget included in his 1880 taxonomy of Oncophorus.

[13][14] The name only became available in 1838 as Nirmus attenatus, when Hermann Burmeister provided the same indication to Schrank but without marking it as questionable.

Three of its junior synonyms were named and circumscribed by M. A. Carriker, Jr. Carriker named the genus Furnaricola in 1944; his circumscription included its type species F. acutifrons (with two subspecies, F. a. acutifrons and F. a. subsimilis) as well as F. cephalosa, F. chunchotambo, F. heterocephala, F. laticephala, F. parvigenitalis, and F. titicacae, which were all described in the same work.

[20] By 1952, Hopkins and Clay had classified Furnaricola, Epipicus, and Corvicola as junior synonyms of Rallicola.

Emerson [Wikidata] treated Furnaricola as its own genus in 1987,[22] but in 1993 Price and Dale Clayton concurred with Hopkins and Clay's synonymization.

[25] Rallicola can also be found on birds in the Aramidae (limpkins), and Psophiidae (trumpeters) families.

[26] The sole Huiacola species R. (H.) extinctus was found on the extinct huia bird, in the family Callaeidae.

[28] Species in the subgenus Rallicola can be found in North America,[29] the Pacific Islands, and New Zealand.
