Type host: Scalopus aquaticus (Linnaeus, 1758), Eastern American mole.

Other hosts: None to date.

Type locality: NORTH AMERICA: USA, Texas, Motley Co.

Geographic distribution: NORTH AMERICA: USA, Texas.

Description of oocyst: Oocyst shape: subspheroid; number of walls: 2; wall thickness: ~1.0; wall characteristics: outer layer smooth, ~1/2 of total thickness; L x W: 18.9 x 15.7 (14-21 x 12-18); L/W ratio: 1.2 (1.1-1.4); M: absent; OR: absent; PG: 3-5 small granules or 1 large globule, but usually obscured by sporocysts. Distinctive features of oocyst: none.

Description of sporocysts and sporozoites: Sporocyst shape: ellipsoid with large rounded SB at one end and pointed on other end; L x W: 15.0 x 7.2 (11-17 x 6-9); L/W ratio: 2.1 (1.7-2.4); SB: present as a large, rounded cap-like structure completely covering end of sporocyst; end of sporocyst opposite SB slightly pointed; SSB: absent; PSB: absent; SR: present; SR characteristics: a compact mass of large clumped globules; SP: with 1-2 RB. Distinctive features of sporocyst: odd shape of sporocyst with large, rounded SB.

Prevalence: 4/13 (31%).

Sporulation: Exogenous. Oocysts sporulated in 7-10 days in 2.5% aqueous (w/v) potassium dichromate solution at 23 C.

Prepatent and patent periods: Unknown.

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

Materials deposited: Skin, skull, skeleton and tissues of the symbiotype host are preserved in the Mammal Division of the Museum of SW Biology, UNM: MSB No. 42353 (NK 2034, female), J.A. Cook #239, 19 May, 1980. Photosyntypes in the USNPC No. 85987.

Remarks: Of all the Cyclospora spp. described from insectivores, none has the unique shape of its sporocysts with their large, cap-like SB.
