Remarks

Marcus & Marcus (1968) initially established the genus Amyris within the family Planocerida Poche, 1926 , characterizing it by the presence of a seminal vesicle, interpolated prostatic vesicle and a cuticularized cirrus without spines, in addition to the presence of a Lang’s vesicle. Subsequently, Faubel (1983) transferred the genus to the family Notoplanidae based on the morphology of the prostatic vesicle.

Özdikmen (2010) mentioned that the species is included in the family Notocirridae (family that includes the genera Amyris , Chiliplana , Copidoplana , Diplandros , Faubelus , Notoplehnia , Triadomma and Tripyloplana ); however, he did not establish the criteria for its reassignment. Özdikmen (2010) proposed renaming the family Notocirridae due to its invalidity under the rule of homonymy, being a junior homonym of Notocirrus Schmarda, 1861 (a name proposed for polychaetes of the genus Notocirrus ), and in accordance with article 60 of the International Code of Zoological Nomenclature, fourth edition ( ICZN 1999), he proposed to replace the junior homonym Notocirrus Faubel, 1983 with the nomen novum Faubelus . However, Amyris favis should not be included in this family, because the diagnostic characters do not correspond to those established in the family and instead it should be considered as a member of Notoplanidae as established by Faubel (1983).
