3 NEW EIMERIANS IN CAPYBARA (HYDROCHAERIS-HYDROCHAERIS) POPULATIONS FROM EASTERN BOLIVIA AND SOUTHERN VENEZUELA

From June to August 1993, fecal samples were collected from the intest inal tract of 13 juvenile, 4 pre-adult, and 25 adult capybaras (Hydroc haeris hydrochaeris L.) from 10 localities in eastern Bolivia; additio nally, 19 fresh fecal samples were collected in 1994 from capybara her ds at 2 localities in south central Venezuela. Oocysts of 3 eimerians were recovered from the capybara populations in both countries and, af ter study, are described here as new species. Sporulated oocysts of Ei meria trinidadensis n. sp. are subspheroidal, 20.9 x 18.1 (18-23 x 16. 5-21) mu m with sporocysts ovoidal, 9.8 x 6.1 (8-12 x 5-8) mu m. Micro pyle and oocyst residuum are absent, but polar bodies, Stieda bodies, and sporocyst residua are present. Sporulated oocysts of Eimeria ichil oensis n. sp. are ellipsoidal, 26.2 x 21.0 (23-33 x 18-24) mu m with s porocysts ovoidal, 11.6 x 7.4 (9-13.5 x 79) mu m. Micropyle and oocyst residuum absent, but polar bodies, Stieda bodies, and sporocyst resid ua are present. Sporulated oocysts of Eimeria boliviensis n. sp. are e llipsoidal, 35.9 x 25.7 (29-45 x 20-30) mu m with sporocysts elongate ovoidal, 16.0 x 10.4 (12-20 x 8-12) mu m. Micropyle and oocyst residuu m are absent, but polar bodies, Stieda bodies, and sporocyst residua a re present.
