Nomenclature

The name originally given to this species by Fabricius was ''Cimex rubens'', a name earlier used in 1780 for a different, unrelated species, making Fabricius' name a junior homonym. However, since neither of the two taxa so named have been considered to belong to the genus ''Cimex'' after 1899, the senior homonym is no longer used as a valid name (it is a junior synonym of '' Deraeocoris ruber'' (Linnaeus, 1758)), and the name ''Pycanum rubens'' is still in use by some sources, under Article 23.9 of the

ICZN The International Code of Zoological Nomenclature (ICZN) is a widely accepted convention in zoology that rules the formal scientific naming of organisms treated as animals. It is also informally known as the ICZN Code, for its publisher, the I ...

. Fabricius' name ''rubens'' remains the valid name for this species, despite numerous sources using the junior name, ''Pycanum alternatum'' (e.g.GBIF
