Eimeria motleiensis Ford and Duszynski, 1988

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

Other hosts: None reported to date.

Type locality: NORH 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, mammillated, ~2/3 of total thickness; inner, smooth; L x W: 17.0 x 15.3 (15-20 x 13-18); L/W ratio: 1.1 (1.0-1.2); M: absent; OR: present; PG: absent. Distinctive features of oocyst: knobby, mammillated outer wal, absence of PG.

Description of sporocysts and sporozoites: Sporocyst shape: ovoid; L x W: 10.7 x 6.8 (10-13 x 6-8); L/W ratio: 1.6 (1.4-1.75); SB: present; SSB: present, same width as SB; PSB: absent; SR: present; SR characteristics: small granules as compact sphere or band-shaped body between SP; SP: with 2 prominent RB. Distinctive features of sporocyst: combination of SB-SSB complex and 2 RB in SP.

Prevalence: 7/13 (54%).

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. 42354 (NK 2048), D.W Moore #719, 20 May, 1980. Photosyntypes in the USNPC No. 85998.

Remarks: Oosysts of this species resemble those of E.bentongi, E. blarinae, and E. madagascarensis. They differ from those of E. bentongi by having an oocyst with a sculptured (vs smooth) outer wall and an OR; they also lack a PG that is present in E. bentongi and have sporocysts with a SB, which the latter lacks. They differ from those of E. blarinae by being somewhat smaller (17 x 15 vs 21 x 18), by lacking a PG, and by having a SB. They differ from those of E. madagascarensis by having a thicker oocyst wall (>1.0 vs 0.5) that is sculptured rather than smooth, by having an OR and sporocysts with a SSB, and by not having a PG. .
