The genus Gigantorhynchus (type species = G. dubius Sapelnikov & Malygina, 1977, by original designation) was
established by Sapelnikov & Malygina (1977: 62) for a distinctive fossil brachiopod from Eastern Alai (Southern Tien
Shan, Kyrgyzstan) which subsequently served as type of a subfamily (Gigantorhynchinae Savage 1996). However, the
name Gigantorhynchus was preoccupied by a living worm genus published by Hamann (1892: 196) (Vermes:
Acanthocephala: Gigantorhynchida: Gigantorhynchidae Hamann 1892). The worm Gigantorhynchus is well recognized
in modern zoology, serving as type of a distinct order and family (Gigantorhynchida and Gigantorhynchidae Hamann
1892, respectively).
In accordance with Article 60 of the International Code of Zoological Nomenclature, the new name Alairhynchus is
here proposed as a replacement name for Gigantorhynchus Sapelnikov & Malygina 1997 as well as the new subfamily
name Alairhynchinae nom. nov. to replace the invalid later homonym Gigantorhynchinae Savage 1996 (non
Gigantorhynchidae Hamann 1892).
