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

Other hosts: Probably none; see Remarks below.

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

Geographic distribution: AFRICA: Madagascar.

Description of oocyst: Oocyst shape: spheroid to subspheroid; number of walls: 1; wall thickness: ~0.5; wall characteristics: thin, smooth, colorless; L x W: 16.3 x 15.4 (13-22 x 12-19); L/W ratio: 1.05; M: absent; OR: absent; PG: 1. Distinctive features of oocyst: very thin wall.

Description of sporocysts and sporozoites: Sporocyst shape: ovoid; L x W: 11.1 x 7.1 (10-12.5 x 6-8); L/W ratio: 1.6; SB: present; SSB: absent (?); PSB: absent; SR: present; SR characteristics: irregular mass of granules; SP: short, stocky, without clear globules and lie sideways in sporocyst. Distinctive features of sporocyst: short, stocky shape of SP.

Prevalence: 2/5 (40%).

Sporulation: Exogenous. Oocysts sporulated in 4 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 from S. setosus to Tenrec ecaudatus.

Materials deposited: None.

Remarks: Given the size and shape of the SB in his line drawing, we think the sporocysts of this species also may possess a SSB. Although Uilenberg (1967) could not transmit this species to T. ecaudatus, he said he also found it in 3/6 (50%) T. ecaudatus and, later (Uilenberg, 1970), in 2/10 Hemicentetes semispinosus. Pellérdy (1969, 1974) assigned the form Uilenberg saw in T. ecaudatus to a new species he called E. uilenbergi, which is now listed as a species inquirendae..
