Hirschmanniella nom. nov. for Hirschmannia

Hirschmanniella nom. nov. for Hirschmannia 471 Michel Luc & J. Basil GOODEY 1): Hirschmanniella nom. nov. f or Hirschmannia. Dr. J. Heyns has pointed out to us that the name Hirschmannia, which we erected in 1962 (Luc & Goodey, 1962) for some species originally in Radopholus, is preoccupied by a Crustacean (Elofson, 1941). Accordingly we change the name for the nematode genus to Hirschmanniella nom. nov. with the following new combinations: Hirschmanniella sPinicalldrlta (Schuurmans Stekhoven, 1944) n. comb. -type.
