Taxonomy notes

previously included H. oniscus, as well as the name laticeps, which is considered a synonym of H. megacephalus; the Mammals of South America in 2015 recognized seuanezi as a synonym of laticeps and stated that Brennand et al., 2013 recognized both laticeps and seuanezi as separate species, which appears to have been a misinterpretation of the results of Brennand et al., 2013, as they suggested that the species normally named H. laticeps is better known as H. seuanezi since the lectotype of laticeps was shown to represent an individual of H. megacephalus (along with the name saltator, which was based on the lectotype of laticeps); Brennand et al., 2013 is followed here given that more recent authors appear to have misinterpreted their findings; moved from Oryzomys to the recently described Hylaeamys
