Helionomus Gray, 1842

Schleip, Wulf D. & O'Shea, Mark, 2010, Annotated checklist of the recent and extinct pythons (Serpentes, Pythonidae), with notes on nomenclature, taxonomy, and distribution, ZooKeys 66, pp. 29-80 : 41

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 .
