Observation of a very rare beetle of the species Bergidora picturella (Coleoptera; Buprestidae)

One of my personal goals on Inaturalist is photograph and publish very rare taxa. For this purpose, I defined as very rare the taxa that have less than 10 observations on Inaturalist. In december 26 I did a morning walk in a rural road while photographing biodiversity. I found a beautiful beetle in flowers of Verbena rigida.

I posted the photos in the Inaturalist site and the beetle was identified as Bergidora picturella by the user fmiudo.

The species is well known for Argentina but I was incapable of find any reference of the species for Brazil.
This can be the first evidence of the species for Rio Grande do Sul state and Brazil. Bergidora picturella looks intimaly related with plants of the genus Verbena because almost all the observations in the site Inaturalist the beetle are in Verbena flowers.

Why it is rare?

Occurrence area in South America where have fewers naturalists.
Small organism, better photographed with macro lens.
Possibly small populations.

First Identifications of Carathis australis (Lepidoptera; Erebidae) on Inaturalist.

Carathis australis was first described by Rothschild, 1909 (https://archive.org/details/ser8annalsmagazi04londuoft/page/208/mode/1up?view=theater) with type locality in the brazilian state of Santa Catarina. A plate with Carathis australis picture was also provided in 1910 (https://archive.org/details/novitateszoologi17lond/page/n607/mode/2up?view=theater). Recently, a review of the genus Carathis was published with key to species, diagnosis and pictures of museum specimens (Becker, 2011).

While conducting a search in Inaturalist site looking for Carathis byblis in the state of Paraná I found a moth with similar pattern but different from C. byblis. Investigating the genus in the site Funet.fi I found another species in the genus sympathric with C. byblis (https://ftp.funet.fi/index/Tree_of_life/insecta/lepidoptera/ditrysia/noctuoidea/arctiidae/arctiinae/carathis/). The species is Carathis australis that, based in the pictures and review paper, fully matched the observations in Inaturalist.

It was found 2 observations recognized as Carathis australis in the brazilian state of Paraná: https://www.inaturalist.org/observations/177333138, https://www.inaturalist.org/observations/182037714.

This was the first identifications of C. australis in Inaturalist and also the first known photographs of living specimens. By now the species is only known for the brazilian states of Santa Catarina and Paraná (Becker, 2011), but Inaturalist have potential to extend the known distribution because it's a species that can be recognized by photographs.

Observation of a very rare bush of the species Miconia purpureovillosa (Myrtales; Melastomataceae).

One of my personal goals on Inaturalist is photograph and publish very rare taxa. For this purpose, I defined as very rare the taxa that have less than 10 observations on Inaturalist. In October 4 I decided explore a new trail in Ilópolis. The vegetation is characterized by Pinus elliottii, exhotic and invasive, that grew and formed an under forest with native vegetation. I found this Melastomataceae bush that I recognized as Miconia, but a species that I never saw before.

I used Flora e Funga do Brasil internet site to find the species of Miconia occuring in Rio Grande do Sul state, many of them was in the genus Leandra. A good character that I found to separate the species was anther colour, only two species have pink anther in Rio Grande do Sul, M. purpureovillosa and M. erostrata. I compared the two species in speciesLink internet site (https://specieslink.net/search/), I found that M. erostrata have a more rounded leave and is whitish underside. This was the second observation in Inaturalist identified as Miconia purpureovillosa.

The species is known to the brazilian states of Minas Gerais, São Paulo, Paraná, Santa Catarina, Rio Grande do Sul and Rio de Janeiro.

Why is rare?

Occurrence area in South America where have fewers naturalists.
Hard to identify and there are few botanists identifying in the area of occurrence
The bush attract little attention and live in areas of low human traffic.
Need key photos to identify.

Observation of a very rare tree of the species Ilex brevicuspis (Aquifoliales; Aquifoliaceae).

Recently, I participated in a class of trees identification and registered lots of individuals identified by Martin Grings, a local botanist. One of the species identified was Ilex brevicuspis that was just the fourth observation identified as this species on Inaturalist site.

The species is known to the brazilian states of Minas Gerais, São Paulo, Paraná, Santa Catarina and Rio Grande do Sul, and in the province of Misiones in Argentina.

Why is rare?

  • Occurrence area in South America where have fewers naturalists.
  • Ilex brevicuspis can be hard to make photographs of key characteristics like leaves, flowers and fruits because they are too high.
  • Hard to identify and there are few botanists identifying in the area of occurrence
  • The tree doesn't attract attention and live in areas of low human traffic.

First observation of Sisyrinchium platycaule (Asparagales; Iridaceae) on Inaturalist.

Make the first observation on Inaturalist is an important event because this observation can be used later to made more identifications of the same species. The genus Sisyrinchium have around 150 described species and many of this species have very similiar morphology.

October 27 I decided make some photos, I choosed a pasture to explore for herbs and insects. I found some Sisyrinchium, I was looking for rare species and ignored Sisyrinchium micranthum. Three forms looked diferent from S. micranthum and I took shots. Later, when I upload the pictures I was convinced that one of them are S. micranthum, despite it looked diferent at field.

To identify I consulted Flora e Funga do Brasil site (https://floradobrasil.jbrj.gov.br/reflora/listaBrasil/PrincipalUC/PrincipalUC.do;jsessionid=F0F858585E5FCCDE8A4EFA8F22A5EB6A) and made a search selcting genus Sisyrinchium and state of Rio Grande do Sul. Most of the species have pictures and I could compare with my own photos. One of them, that I thinked was S. micranthum, matched perfectly with S. platycaule images. Compared with S. micranthum is a smaller plant with free tepals, with a different tepal color pattern.

It was the first observation on Inaturalist identified as S. platycaule. I found another of my observations that matched as S. platycaule, misidentified as S. micranthum. Later, I searched the site for more observations of this species and found a total of 7 observations.

I believe this species was overlooked because is hard to identify and don't attract much attention of naturalists at field. Also, the region of occurence still have very little botanic identifiers.

An observation of a very rare tree of the species Picrasma crenata (Sapindales; Simaroubaceae).

One of my personal goals on Inaturalist is photograph and publish very rare taxa. For this purpose, I defined as very rare the taxa that have less than 10 observations on Inaturalist. Recently, I participated in a class of trees identification and registered lots of individuals identified by Martin Grings, a local botanist. One of the species identified was Picrasma crenata that was the third observation identified as this species on Inaturalist site.

The key characteristics for the identification was leaves alternate, imparipinnate, opposite leaflets with asymmetrical base, crenulate to serrate margin and branch with bitter taste.

The species is known to the brazilian states of Bahia, Pernambuco, Minas Gerais, Rio de Janeiro, São Paulo, Paraná, Santa Catarina and Rio Grande do Sul, north of Argentina and Paraguay. Picrasma crenata is hard to make photographs of key characteristics like leaves, flowers and fruits beacause they are too high or are too small. The wood is very bitter and has medicinal properties.

Distributional area of Aclytia terra (Lepidoptera; Erebidae).

Aclytia terra is a species first described by Schaus, 1896 (https://archive.org/details/journalofnewyork41896newy/page/133/mode/1up?view=theater). Hampson, 1898 also described the species and provided a figure (https://archive.org/details/catalogueoflepid01brituoft/page/458/mode/1up?view=theater, https://archive.org/details/catalogueoflepid13brit/page/n73/mode/2up?view=theater). The species was previously known to brazilian states of Rio Grande do Sul, Santa Catarina, Paraná, São Paulo, Rio de Janeiro, Mato Grosso, Goiás and Rondônia; and Argentina and Ecuador countries (Ferro, 2007).

To improve the knowledge of the species distribution, I compared Inaturalist observations with Hampson illustration and BOLD Systems images (https://www.boldsystems.org/index.php/Taxbrowser_Taxonpage?taxid=355032). The search was made in the brazilian states of Rio Grande do Sul, Santa Catarina, Paraná, São Paulo, Minas Gerais, Rio de Janeiro, Espírito Santo Mato Grosso do Sul, Mato Grosso, Goiás, Distrito Federal, Bahia, Tocantins, Pará, Amazonas and Rondônia; argentinian provinces of Misiones and Corrientes; and in the countries of Uruguay, Paraguay and Bolivia. Photos of adults previously identified at least in the subfamily Arctiinae was checked. "Research grade" observations was excluded of the search.

It was found 53 observations recognized as Aclytia terra: 6 from Rio Grande do Sul, 21 from Paraná, 3 from São Paulo, 1 from Rio de Janeiro, 1 from Minas Gerais, 18 from Misiones, 1 from Corrientes, 1 from Peru, 1 from Ecuador and 1 from Guatemala.

This is the first evidence of this species to Minas Gerais. It can be the first evidence of this species for Peru, Ecuador and Guatemala, but I was unable to confirm or refute this evidence.

First Identifications of Isanthrene melas (Lepidoptera; Erebidae) on Inaturalist.

Isanthrene melas was first described as Sphinx melas Cramer, 1775, that gave a plate of the species (https://archive.org/details/deuitlandschekap11779cram/page/n220/mode/1up?view=theater). Later, Hampson, 1898 transferred the species to genus Isanthrene (https://archive.org/details/catalogueoflepid01brituoft/page/173/mode/1up?view=theater). The species was previously known to Suriname, French Guiana and the Brazilian states of Amazonas, Pará, Mato Grosso, Rio de Janeiro, Paraná and Rio Grande do Sul (Ferro, 2007).

To improve the knowledge of the species distribution, I compared Inaturalist observations with Cramer illustration and BOLD Systems image (https://www.boldsystems.org/index.php/Taxbrowser_Taxonpage?taxid=1130525). The search was made in the brazilian states of Rio Grande do Sul, Santa Catarina, Paraná, São Paulo, Minas Gerais, Rio de Janeiro, Mato Grosso do Sul, Mato Grosso, Goiás, Distrito Federal, Bahia, Tocantins, Maranhão, Pará, Amapá, Amazonas, Rondônia, Acre and Roraima; argentinian provinces of Misiones and Corrientes; and in the countries of Uruguay, Paraguay, Bolivia, Guyana, Suriname and French Guiana. Photos of adults previously identified at least in the subfamily Arctiinae was checked. "Research grade" observations was excluded of the search.

It was found 18 observations recognized as Isanthrene melas: 1 from Rio Grande do Sul, 2 from Paraná, 5 from Rio de Janeiro, 1 from Mato Grosso do Sul, 1 from Minas Gerais and 7 from Misiones.

Mostly of the observations was misidentified as Isanthrene incendiaria, a similar sympatric species that can be differentiated by the thorax and abdomen first segment lines and dots. No previous identifications of the species had been made at Inaturalist site before this search and it's the first known photos of living specimens of Isanthrene melas. This is the first evidence of this species to Mato Grosso do Sul and Missiones (first evidence for Argentina). The species has a wide distribution but is somewhat difficult to find.

Distributional area of Callopistria fimbripes (Lepidoptera, Noctuidae) on Inaturalist.

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.

First identifications on Inaturalist of a very rare noctuidae moth Macapta obliqua (Lepidoptera, Noctuidae).

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.
