See account by Edwards, 1974, Occas. Pap. Mus. Nat. Hist. Univ. Kansas, 30: 7–10. Without discussion, considered a synonym of Allobates brunneus (as Colostethus brunneus) by Silverstone, 1976, Sci. Bull. Nat. Hist. Mus. Los Angeles Co., 27: 6. Schlüter, 1980, Salamandra, 16: 149–161, described the advertisement call. Duellman, 1978, Misc. Publ. Mus. Nat. Hist. Univ. Kansas, 65: 121–122, provided a brief account and characterization of the call and tadpole. Rodríguez and Duellman, 1994, Univ. Kansas Mus. Nat. Hist. Spec. Publ., 22: 16, provided a brief account as Colostethus marchesianus. Prior to the revision of Grant, Frost, Caldwell, Gagliardo, Haddad, Kok, Means, Noonan, Schargel, and Wheeler, 2006, Bull. Am. Mus. Nat. Hist., 299, placed in the Colostethus brunneus group (Group II) of Rivero, 1990 "1988", Mem. Soc. Cienc. Nat. La Salle, 48: 3–32, or the the Colostethus trilineatus group of Morales, 2002 "2000", Publ. Asoc. Amigos Doñana, 13: 1–59 (who provided a species account). See account by Coloma, 1995, Misc. Publ. Mus. Nat. Hist. Univ. Kansas, 87: 41. The report by Reichle and Köhler, 1996, Herpetofauna, Weinstadt, 18: 32–34, for Bolivia is actually Allobates trilineatus according to De la Riva, Köhler, Lötters, and Reichle, 2000, Rev. Esp. Herpetol., 14: 29. Caldwell, Lima, and Keller, 2002, Copeia, 2002: 157–165, reported on the advertisement call, redescribed topotypes and noted that it is unlikely that the population at the type locality is conspecific with other populations currently referred to as Allobates marchesianus. Caldwell, Lima, and Biavati, 2002, Copeia, 2002: 166–172, described the tadpole and suggested that the nearest relative of Allobates marchesianus is Allobates caeruleodactylus. Morales, 1994, Rev. Esp. Herpetol., 8: 95–103, reported the species for Venezuela. Barrio-Amorós, 2004, Rev. Ecol. Lat. Am., 9: 7, reported on distribution and relevant literature. Barrio-Amorós and Santos, 2009, Phyllomedusa, 8: 98, implied that records of Allobates marchesianus from Venezuela apply to an unnamed species. França and Venâncio, 2010, Biotemas, 23: 71–84, provided a record for the municipality of Boca do Acre, Amazonas, with a brief discussion of the range. For identification of larvae (as Colostethus marchesianus) in central Amazonia, Brazil, see Hero, 1990, Amazoniana, 11: 201–262. Señaris and Rojas-Runjaic, 2020, in Rull and Carnaval (eds.), Neotrop. Divers. Patterns Process.: 571–632, commented on range and conservation status of Allobates aff. marchesianus in the Venezuelan Guayana. Metcalf, Marsh, Torres Pacaya, Graham, and Gunnels, 2020, Herpetol. Notes, 13: 753–767, reported the species from the Santa Cruz Forest Reserve, Loreto, northeastern Peru. Taucce, Costa-Campos, Carvalho, and Michalski, 2022, Eur. J. Taxon., 836: 96–130, rejected earlier records from Amapá, Brazil, as based on misidentifications.
