Bothrops brazili was split into:
Bothrops brazili: South of the Amazon, and all current records from Ecuador
Bothrops oligobalius: North of the Amazon, including all Colombian records of "B. brazili", Venezuela, the Guyanas, and all of Brazil north of the Amazon.
Reference:
Francisco Dal Vechio, Ivan Prates, Felipe G. Grazziotin, Roberta Graboski & Miguel Trefaut Rodrigues (2020) Molecular and phenotypic data reveal a new Amazonian species of pit vipers (Serpentes: Viperidae: Bothrops), Journal of Natural History, 54:37-38, 2415-2437, DOI: 10.1080/00222933.2020.1845835
OK here's a draft split https://www.inaturalist.org/taxon_changes/97605
Can you check these atlases:
https://www.inaturalist.org/atlases/37395
https://www.inaturalist.org/atlases/37396
where there are 0 or both atlaes overlapping existing IDs of Bothrops brazili will be replaced by IDs of Bothrops
where there's just one atlas existing IDs of Bothrops brazili will be left alone or replaced with Bothrops oligobalius
the more we can separate atlas overlap the better
OK, some issues with the Atlases:
B. oligobalius does not occur in Peru or Bolivia, and probably not in Ecuador. In Brazil, it only occurs north of the Amazon/Solimões
B. brazili does not occur north of the Amazon/Solimões in Brazil.
The records of "brazili" from French Guiana and the Brazilian state of Amapá are all B. oligobalius.
As far as we know, there is no overlap between the two species.
OK I fixed up the atlases a bit more but their still not perfect so some existing IDs of B brazili were replaced with IDs of Bothrops
where they overlapped. Here's all the existing IDs of B brazili that were replaced https://www.inaturalist.org/identifications?current=any&taxon_id=30796 in case you want to check on where those observations ended up
I am not sure why there should be any overlap - there are no known areas of overlap according to Vecchio et al.'s paper, and the two species seem to be separated by the Amazon and Putumayo Rivers...
I will take a look at the list of records later today.
overlap in the atlases, not the species
OK, there seem to be two records that have become "orphaned" as a result of the split:
https://www.inaturalist.org/observations/33665808 and https://www.inaturalist.org/observations/37105900 - both are Bothrops brazili, and I have inserted an ID accordingly.
The issue seems to be that the Atlas divides by administrative boundaries - it is to be expected that both B. brazili and B. oligobalius occur in different parts of Pará and Amazonas states in Brazil. The dividing line is the Amazon/Solimões river, not any state line.
great, thank you for sorting out the records that were rolled back to Bothrops and for spearheading this split
Glad I could help!

what was Bothrops brazili (sensu lato) split into and what are the respective distributions?
