[4] The type locality for this species is: "Centro de Pesquisas e Conservação da Natureza (CPCN) Pró Mata, at the following coordinates: 29°30′S 50°10′W / 29.500°S 50.167°W / -29.500; -50.167, at an altitude of 950 meters above sea level, in the municipality of São Francisco de Paula in the state of Rio Grande do Sul, Brazil.

"[4] The designated holotype is catalogued as follows: MCP 2422; an adult female captured on 20 January 1996, by Axel Kwet and Marcos Di Bernardo.

"[5] The species name dibernardoi is an eponym referring to the surname of the person to whom the frog is dedicated, the herpetologist Marcos Di Bernardo, in recognition of his valuable contributions to the knowledge of the herpetofauna of Rio Grande do Sul.

[4] It also lives in the very northeastern part of Argentina, in the province of Misiones, according to material from the El Soberbio (department of Guaraní, at 190 m), reported under the name Phrynohyas imitatrix.

[4][8][9][10] Scientists suspect this frog has a wide distribution between altitudes of 150 and 1100 meters above sea level throughout the Sierra Geral and adjacent areas, with other possible populations in western Paraguay and in the state of Paraná in Brazil.
