Rhosus ovata was first described by Rothschild 1896 as Pycnodontis ovata (https://archive.org/details/novitateszoologi03lond/page/98/mode/1up?view=theater). A synonym was published at the same year by Schaus 1896 by the name Rhosus unipuncta (https://archive.org/details/journalofnewyork41896newy/page/153/mode/1up?view=theater). Hampson 1910, who made the synonymization, transfered the species to the genus Rhosus (https://archive.org/details/catalogueoflepid09brituoft/page/414/mode/1up?view=theater).

To improve the knowledge of this species distribution, I compared Inaturalist observations with previously identified images of the species in the sites Inaturalist and leps.fieldguide (https://leps.fieldguide.ai/figures?category=59bb136c929d3d10ea9648e9). The search was made in the brazilian states of Rio Grande do Sul, Santa Catarina, Paraná, São Paulo, Rio de Janeiro, Minas Gerais, Goiás, Espírito Santo, Bahia, Alagoas, Pernambuco, Piauí, Tocantins, Mato Grosso, Mato Grosso do Sul and Distrito Federal; the argentinian provinces of Misiones, Corrientes, Entre Ríos, Santa Fe, Buenos Aires, Córdoba, La Pampa and Río Negro; and in the countries of Uruguay and Paraguay. Photos of adults previously identified at least in the family Noctuidae was checked. "Research grade" observations was excluded of the search.

It was found 17 observations of Rhosus ovata in the argentinian provinces of Buenos Aires, Corrientes and Misiones; Uruguay; and the brazilian states of Rio Grande do Sul, Paraná, São Paulo and Distrito Federal.
Another known locations of Rhosus ovata are the brazilian states of Bahia, type locality Rothschild 1896, Rio de Janeiro and Minas Gerais from images of leps.fieldguide site.

Macapta obliqua was first described by Jones, 1914 and the type locality is Santos, Brazil (https://ftp.funet.fi/pub/sci/bio/life/insecta/lepidoptera/ditrysia/noctuoidea/noctuidae/hadeninae/macapta/). I was unable to find description or pictures of the species. Recently, I found an observation in Inaturalist site claiming that the specimen is a Macapta obliqua that was not included in the site database yet (https://www.inaturalist.org/observations/142344224). Further investigation leaded to the conclusion that a noctuidae specialist identified this specimen (Dr. Eduardo Carneiro dos Santos).

To improve the knowledge of this species distribution, I compared Inaturalist observations with the images of the specimen identified by Dr. Carneiro dos Santos. The search was made in the brazilian states of Rio Grande do Sul, Santa Catarina, Paraná, São Paulo, Rio de Janeiro, Minas Gerais and Mato Grosso do Sul; the argentinian provinces of Misiones and Corrientes; and in the countrie of Uruguay. Photos of adults previously identified at least in the family Noctuidae was checked. "Research grade" observations was excluded of the search.

It was found 4 observations of Macapta obliqua in the search, 2 in Rio Grande do Sul and 2 in Santa Catarina.

Macapta obliqua is now known in the states of Rio Grande do sul, Santa Catarina and São Paulo. The species was known for Rio Grande do Sul before (Silva, Specht & Link, 2004) but Santa Catarina can be the first evidence of Macapta obliqua occurence there. It's still very low data of the distribution of M. obliqua and more data is necessary to unveil the real distribution of this species.

Callopistria fimbripes was first described by Walker, 1885 (https://archive.org/details/listofspecimenso1315brit/page/1773/mode/1up?view=theater). I was unable to find pictures of the species. The species was known from Rio de Janeiro (Walker, 1885) and Rio Grande do Sul (Silva, Specht & Link, 2004).

To improve the knowledge of the species distribution, I compared Inaturalist observations with previously identified pictures of Callopistria fimbripes at same site. The search was made in the brazilian states of Rio Grande do Sul, Santa Catarina, Paraná, Mato Grosso do Sul, São Paulo, Minas Gerais, Rio de Janeiro and Espírito Santo; argentinian provinces of Misiones and Corrientes; and in the countries of Uruguay and Paraguay. Photos of adults previously identified at least in the family Noctuidae was checked. "Research grade" observations was excluded of the search.

It was found 34 observations recognized as Callopistria fimbripes: 3 from Rio Grande do Sul, 2 in Santa Catarina, 19 from Paraná, 6 from Rio de Janeiro and 4 from Misiones.

This can be the first known evidence of C. fimbripes for Santa Catarina, Paraná and Misiones.
