Eimeria from bats of Bolivia: Two new species from vespertilionid bats

Between 1985 and 1987, fecal samples were collected from 71 bats representi ng 14 species (Desmodontidae, Molossidae, Noctilionidae, Phyllostomidae, Ve spertilionidae) from 8 localities in 3 states (Beni,. Pando, Santa Cruz) in Bolivia, South America. Of these, 2 black myotid bats (Vespertilionidae), Myotis nigricans, and 1 tent-making bat (Phyllostomidae), Urodenna magniros trum, had oocysts in their feces that represent undescribed species of Eime ria. The new species from M. nigricans (2/ 4, 50%) has sporulated oocysts t hat are subspheroidal, 18.9 x 16.9 (17-23 x 14-20) mu m, without a micropyl e; oocyst residuum of 6-8 spheroidal globules and 1 highly refractile polar granule are present. The oocyst wall has 2 layers (similar to 1.3 mu m thi ck), with a rough outer layer. Ovoidal sporocysts are 10.1 X 7.4 (7-14 X 5- 10) mu m, with a Stieda body, substieda body, and a sporocyst residuum. The new eimerian species from U. magnirostrum (1/2, 50%) has sporulated oocyst s that are subspheroidal to ellipsoidal, 23.8 x 20.8 (20-26 x 19-24) mu m, without micropyle or oocyst residuum, but 1-3 polar granules are present. T he oocyst wall has 2 layers (similar to 1.5 pm thick), with a rough, mammil ated outer layer. Ovoidal sporocysts are 11.6 X 8.6 (10-12 X 7-10) mu m, wi th a Stieda body, substieda body and a sporocyst residuum.
