Genus Helionomus Gray, 1842 [nomen nudum (APP6), incorrect subsequent spelling (APP4)]
Remarks:
Hoser (2004) obviously intended to resurrect the genus Heleionomus Gray, 1842 but changed the name to " Helionomus ". This constitutes an incorrect subsequent spelling (Art. 33.3). However, the name Helionomus was already used by Gray (1841) listed in the index for Boidae, but no species was assigned to this name, and it is therefore considered a nomen nudum. Also see Heleionomus .
