Formerly treated as conspecific with M. ferox, but the two differ in vocalizations and do not respond to playback of each other’s voice; similarly, species-level separation from M. venezuelensis argued on basis of sympatry in extreme NW Venezuela (near Cerro Alto del Cedro) and in N Colombia (Cansoma, in Bolívar). Analyses of morphological characters and mtDNA#R indicate close affinities with those two species and with M. phaeocephalus, but precise relationships unclear. Ecological and genetic study in zones of parapatry and sympatry would be rewarding, and re-examination needed of geographical distributions of these taxa, especially S & E of L Maracaibo (W Venezuela). Two subspecies recognized.

Subspecies and Distribution
  • M. p. actiosus Ridgway, 1906 – Pacific coast of Costa Rica (Gulf of Nicoya S to point N of Osa Peninsula).
  • M. p. panamensis Lawrence, 1861 – extreme SW Costa Rica (Rincón de Osa, Puerto Jiménez), Panama (Caribbean slope in W Bocas del Toro and from N Coclé E to San Blas, lowlands and foothills on Pacific coast, also Pearl Is, Coiba I, Taboga I and other smaller islands), N & W Colombia (E to Guajira Peninsula, S to Tumaco, in SW Nariño, lower Cauca Valley and upper Magdalena Valley at least to Neiva and Villavieja) and Maracaibo region of NW Venezuela; also recent records from NW Ecuador (N Esmeraldas).
