Other hosts: None reported to date.
Type locality: ASIA: Malaysia, Selangor, Bukit
Geographic distribution: ASIA: Malaysia, Selangor,
Description of oocyst: Oocyst shape: spheroid to
subspheroid; number of walls: 2
stated in original description, but line drawing suggests 3 layers; wall thickness:
1.5; wall characteristics: outer, striated, thin and granular; inner layer(s)
thicker than striated one; L x W: 23 x 20 (19-27 x 16-23); L/W ratio: 1.15
(1.0-1.3); M: absent; OR: absent; PG: present; number of PGs: 1-2. Distinctive
features of oocyst: lack of OR and peculiar number/arrangement of oocyst wall
