Interesting point: the viruses in both studies may belong to the same subgenus — their phylogenetic positions are compatible, even though not analyzed together.
However, Wallau et al. found no FCS at S1/S2 and reported a highly divergent S1 but a conserved S2 region when compared to other betacovs

Both were found in the same genus of bats, but in different locations in Brazil. The phylogenies, although analyzing different regions of the genome, are compatible with the hypothesis that both preprints are referring to very similar viruses.

This new virus may be part of a new subgenus of betacoronaviruses, described in this preprint and tentatively called ambecovirus (American betacoronavirus)

Ambecovirus, a novel Betacoronavirus subgenus circulating in neotropical bats sheds new light on bat-borne coronaviruses evolution
Understanding the viral diversity harboured by wildlife is essential for effective prediction and prevention of future zoonotic outbreaks. Bats, in particular, are recognized as natural reservoirs for...
