Common name: (English) Brown Tinamou, (Portuguese) inhambuguaçu (Fig. 6a). Syntype: MNHN-ZO-2011- 615.
Type-locality: around São Paulo city, Brazil (-23.5, -46.6), 580 m.
Description: dark gray crown and nape; gray sides of head; chocolate brown upperparts, subtly vermiculated with black; rufous brown chest, orange belly paler; buff flanks and undertail coverts, barred with black.
Diagnosis: can be diagnosed from Crypturellus griseiventris by having a rufous chest and an orangish, not buff, belly. It also has a distinct vocal pattern, emitting a series of 2‒13 notes, with the first one being longer and followed by a brief pause.
Voice: emits a single note, similar to a guard whistle. Produces a series of at least 10 notes (up to 84), getting higher and faster in the end. It also produces a shorter series of notes (2‒13), with the first one being longer and followed by a brief pause, before shorter notes are emitted.
Distribution: in Brazil, from southern Bahia to Rio Grande do Sul states, in Atlantic Forest. A few records in Cerrado biome in central Goiás, southern Mato Grosso and northern and southeastern Mato Grosso do Sul. In southeastern Paraguay, in Alto Paraná, Amambay, Caazapá, Canindeyú, Concepción, Guairá and Itapúa departments. In Argentina, in Misiones and Formosa provinces. One record from eastern Uruguay, in Cerro Largo.
