Taxonomy notes

the name vulpinus has been recognized as a distinct species (under two distinct concepts, one leading to a monophyletic relationship with brasiliensis [D'Elía et al., 2015], and the other leading to a paraphyletic relationship [Gonçalves et al., 2015]), although recent molecular studies suggest that the two taxa should be treated as a single species pending further molecular sampling from a larger sample size, thus, vulpinus is considered a synonym of H. brasiliensis here
