Hybrids, not a new rheophilic morph of Vieja hartwegi

" Gómez-González et al. (2018) have presented specimens which they identify as a new rheophilic morph of Vieja hartwegi (Taylor & Miller, 1980). Below we question this species determination and instead demonstrate that they are most likely natural hybrids of Vieja hartwegi and the syntopic Chiapaheros grammodes (Taylor & Miller, 1980). First, we present evidence from the reported specimens, then we compare the evidence with a documented case of hybridization of these two species (Buchhauser, 1999) and other hybrids, and finally we provide additional discussion "
