Coccidian parasites (Apicomplexa: Eimeriidae) from insectivores. VI. Six new species from the eastern mole, Scalopus aquaticus.
Thirteen eastern moles, Scalopus aquaticus, collected in West Texas were examined for coccidian oocysts; 11 (85%) were infected and eight (73%) of these had multiple infections representing two or more species. One cyclosporan, three eimerians, and two isosporans were studied and all are described as new species. Sporulated oocysts of Cyclospora megacephali n. sp. were subspheroidal, 18.5 X 15.7 (14-21 X 12-18) microns; they had sporocysts pointed at one end with Stieda bodies nearly as wide as the sporocysts themselves, and were 15.0 X 7.2 (11-17 X 6-9) microns; C. megacephali was found in four (31%) hosts. Sporulated oocysts of Eimeria scalopi n. sp. were spheroidal to subspheroidal, 13.6 X 12.6 (11-17 X 11-15) microns with sporocysts lemon-shaped, 8.7 X 5.5 (7-10 X 4-7) microns; it was found in six (46%) hosts. Sporulated oocysts of Eimeria aquatici n. sp. were asymmetrically ellipsoidal, 17.0 X 10.6 (14-20 X 9-14) microns with sporocysts elongately ovoidal, 9.0 X 5.2 (8-11 X 4-6) microns; it was found in two (15%) hosts. Sporulated oocysts of Eimeria motleiensis n. sp. were subspheroidal, 17.0 X 15.3 (15-20 X 13-18) microns with sporocysts ovoidal, 10.7 X 6.8 (10-13 X 6-8) microns; it was found in seven (54%) hosts. Sporulated oocysts of Isospora motleiensis n. sp. were spheroidal to subspheroidal, 13.6 X 12.0 (10-17 X 8-15) microns with sporocysts broadly ovoidal, 9.5 X 6.7 (7-11 X 4-8) microns; it was found in nine (69%) hosts. Sporulated oocysts of Isospora aquatici n. sp. were subspheroidal, 20.9 X 18.4 (15-24 X 13-21) microns with sporocysts ellipsoidal, 11.8 X 9.0 (9-14 X 7-11) microns; it was found in two (15%) hosts.
