Abstract

Between 1985 and 1987, fecal samples were collected from 71 bats representing 14 species (Desmodontidae, Molossidae, Noctilionidae, Phyllostomidae, Vespertilionidae) 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), Uroderma magnirostrum, had oocysts in their feces that represent undescribed species of Eimeria. The new species from M. nigricans (2/4, 50%) has sporulated oocysts that are subspheroidal, 18.9 × 16.9 (17-23 × 14-20) μm, without a micropyle; oocyst residuum of 6-8 spheroidal globules and 1 highly refractile polar granule are present. The oocyst wall has 2 layers (~1.3 μm thick), with a rough outer layer. Ovoidal sporocysts are 10.1 × 7.4 (7-14 × 5-10) μm, with a Stieda body, substieda body, and a sporocyst residuum. The new eimerian species from U. magnirostrum (1/2, 50%) has sporulated oocysts that are subspheroidal to ellipsoidal, 23.8 × 20.8 (20-26 × 19-24) μm, without micropyle or oocyst residuum, but 1-3 polar granules are present. The oocyst wall has 2 layers (~1.5 p.m thick), with a rough, mammilated outer layer. Ovoidal sporocysts are 11.6 × 8.6 (10-12 × 7-10) μm, with a Stieda body, substieda body and a sporocyst residuum.
