  1. a Hepatozoon (syn. Haemogregarina) toddi (Wolbach, 1914) when first discovered was tentatively thought to be Hepatozoon (syn. Haemogregarina) varani (Laveran, 1905)
  2. bSmith [3] during a systematic revision of species of the Hepatozoidae transferred many of the above species from the genus Haemogregarina Danilewsky, 1885 to the genus Hepatozoon Miller, 1908
