Moenkhausia heikoi Géry & Zarske, 2004 and Astyanax dnophos Lima & Zuanon, 2004 were described almost simultaneously from the Rio Xingú drainage in Brazil. A comparison of the holotypes of the two nominal species revealed that they are conspecific, despite their original assignments to two different genera. The publication of the description of M. heikoi preceded that of A. dnophos by five days and has priority over the latter, which becomes a subjective junior synonym.
