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

Sat Apr 11 10:55:59 CDT 2020

Certain authors seem to have favored different usage; for example,
DeGregorio spelled the freshwater snail Io as Jo.  Similar issues exist for
v and w, such as a clam from near the Waccamaw River named Pecten
vaccamavensis.  (As a subjective synomym, it's not causing much trouble.)
