When I initially split Paradoxurus hermaphroditus sensu lato (https://www.inaturalist.org/taxon_changes/61386), I retained the epithet musanga indiscriminately because that was what the MDD had used on their taxon page (https://mammaldiversity.org/species-account.php?genus=paradoxurus&species=musanga). However, as pointed out by @leptonia, they cite Veron et al. (2014) as the source for the species name, which adopts a different epithet (musangus). Because there was no explanation as to why the epithet was different between the cited literature and the MDD taxon page under "Taxon Notes", I had assumed this was in error. However, from what @jwidness described (quoted below) and @jakob echoed, it was likely changed to follow Article 31 of the ICZN. Please see the previous taxon swap for additional context (https://www.inaturalist.org/taxon_swaps/61471).

"The original name was Viverra musanga, from the Malay word for the animal, musang (https://www.biodiversitylibrary.org/page/754982#page/281/mode/1up). I think that makes musanga a noun in apposition rather than an adjective, which would mean it doesn't change gender when the genus changes (https://code.iczn.org/formation-and-treatment-of-names/article-31-species-group-names)" - @jwidness
