The blackish antbird was described by the German ornithologists Jean Cabanis and Ferdinand Heine in 1860 and given the binomial name Percnostola nigrescens.[2] The specific epithet is from the Latin nigrescens "blackish" (from nigrescere "to become black").[3] The antbird was subsequently included in the genus Cercomacra but a molecular phylogenetic study published in 2014 found that Cercomacra was polyphyletic. The genus was split to create two monophyletic genera and six species including the blackish antbird were moved to the newly erected genus Cercomacroides.[4][5]

There are five subspecies:[5]

  • Cercomacroides nigrescens nigrescens (Cabanis & Heine, 1860) – Suriname, French Guiana and ne Brazil
  • Cercomacroides nigrescens aequatorialis (Zimmer, JT, 1931) – south central Colombia, east Ecuador and northeast Peru
  • Cercomacroides nigrescens notata (Zimmer, JT, 1931) – central Peru
  • Cercomacroides nigrescens approximans (Pelzeln, 1868) – central Brazil
  • Cercomacroides nigrescens ochrogyna Snethlage, E, 1928) – east central Brazil
