Type host: Chaerephon bemmeleni (Jentink, 1879) (Syn. Tadarida bemmeleni), Lesser mastiff bat .

Other hosts: None reported to date.

Type locality: AFRICA: Liberia.

Geographic distribution: AFRICA: Liberia.

Description of oocyst: Oocyst shape: ovoidal, somewhat flattened and thickened at 1 end (line drawing); number of walls: 1 (line drawing); wall thickness: not given; wall characteristics: smooth; L x W: 21.6 x 18.2 (19-24 x 17-19); L/W ratio: 1.2; M: present (?); M characteristics: small, around which there is a somewhat flattened ridge (line drawing); OR: present; OR characteristics: "abundant" number of coarse granules that take up about the top 1/2 of the space within the oocyst (line drawing); PG: absent. Distinctive features of oocyst: 1 of the 3 (?) eimeriid oocysts from bats with a M; the flattening at one end also sets it apart from other species.

Description of sporocysts and sporozoites: Sporocyst shape: ovoidal; L x W: 8.5 x 7.4 (8-9 x 7-8); L/W ratio: 1.1; SB: present as a dark, pointed structure at one end of sporocyst; SSB: absent; PSB: absent; SR: absent; SP: spheroidal, 3.4 x 3.4 (3-4 x 3-4) and "hyaline;" RB apparently absent. Distinctive features of sporocyst: distinct SB and rounded, "hyaline" (degenerate?) SP.

Prevalence: 2/4 (67%).

Sporulation: Exogenous. Oocysts sporulated in 2-4 in 2% chromic acid solution.

Prepatent and patent periods: Unknown.

Site of infection: Epithelial cells of the posterior third of the small intestine.

Endogenous stages: Meronts had crescentic-shaped merozoites arranged with ends all pointed in the same direction. Mircogametocytes had numerous nuclei and pronounced septa formation in the cytoplasm. Macrogametocytes were thin-walled with a large eccentric vesicular nucleus that had a large, eccentric karyosome.

Materials deposited: None.

Remarks: This species has not been reported since its original description.
