Notes. – This species is found in Amazonian Colombia, Venezuela, Brazil, and Peru (TAYLOR, 2005). See TAYLOR (2005) and DELPRETE & KIRKBRIDE (2015) for synonymy. See TAYLOR (2005) also for discussion of the nomenclatural confusion between this species and the unrelated species Psychotria turbinella var. sororiella (Müll. Arg.) Steyerm.

TAYLOR (2005) attempted to designate a duplicate of the type collection in the Martius herbarium at M, which Müller likely studied, as the lectotype for Mapouria podocephala However this lectotypification was inaccurate because this specimen is not deposited at M, but is at BR [BR0000005523177]. DELPRETE & KIRKBRIDE (2015: 78) noted that TAYLOR’s lectotypification (2005) was also invalid because it did not include the words “designated here” (Art. 7.10 and Art. 7 Note 2). They presented a valid lectotypification for this name, and chose as the lectotype a specimen at K that Müller probably never saw.
