[Taxacom] Iapyx vs. Japyx (etc.) in Diplura

[Tony Rees]

Dear Taxacomers,

In the Hexapod class (formerly order) Diplura, two forms of the genus name
Iapyx Haliday, 1864 are in current use, namely Iapyx and Japyx, same for
the family names based on this genus (Iapygidae/Japygidae); Japyx can
perhaps be construed either as a lapsus, a subsequent emendation, or a
legitimate correction; the name was originally published as

Haliday, A.H. 1864. *Iapyx,* a new genus of insects belonging to the stirps
Thysanura, in the order Neuroptera.

 *24*: 441-447 .

In the absence of an ICZN ruling on the matter, are there any rules or
precedents to decide which spelling is preferable to use, and/or the
technically "correct" one?
