Type host: Setifer setosus (Schreber, 1777), Large Madagascar "hedgehog."

Other hosts: None reported to date.

Type locality: FRICA: Madagascar, ~15 km NE of Tananarive.

Geographic distribution: AFRICA: Madagascar.

Description of oocyst: Oocyst shape: spheroid to subspheroid; number of walls: 1; wall thickness: 2.0; wall characteristics: thick, rough, striated, yellow-chestnut colored; L x W: 24.6 x 21.8 (21-29 x 18-25); L/W ratio: 1.1; M: absent; OR: absent; PG: 1. Distinctive features of oocyst: thick, striated, colored outer wall.

Description of sporocysts and sporozoites: Sporocyst shape: ovoid to football-shaped, slightly pointed at end opposite SB; L x W: 14.3 x 8.9 (13-19 x 8-11.5); L/W ratio: 1.6; SB: present; SSB: absent (?); PSB: absent; SR: present; SR characteristics: irregular mass of large and small granules in center of sporocyst; SP: short, stocky, without clear globules and often lie sideways in sporocyst. Distinctive features of sporocyst: football-shaped with short, stocky SP without RB.

Prevalence: 2/5 (40%).

Sporulation: Oocysts sporulated in 8-9 days in 2% aqueous (w/v) potassium "bichromate" solution at ~25 C.

Prepatent and patent periods: Unknown.

Site of infection: Unknown. Oocysts recovered from feces and intestinal contents.

Cross-transmission: Uilenberg (1967) was not able to transmit oocysts of this species fromS. setosus to Tenrec ecaudatus.

Materials deposited: None.

Remarks: The size and shape of the SB in the original drawing suggest that a SSB may be present in the sporulated oocysts of this species. This species has not been reported since its original description.
