Abstract
Protozoans found in the posterior intestine of Leptodeira maculata taken in Monterrico, Taxisco, Santa Rosa, Guatemala, correspond to: Zellereilla boyonai n. sp., and opalinid of ellipsoidal character (56-181x33-100 ; 126.84 x 76.19 µm), disposition and size nuclei (diameter 7 -24; 15.82 µm), with uniform citoplasm ; Nyctotherus uscae n. sp., a heterotrichous ciliate, typically ovoid (100-132x66-92; 117 x 78 µm) whose peristome (42-56; 49 µm) is hook shaped, extending from about the ecuatorial level and passing below and parallel to the macronucleus (34-43x15-25 ; 39x20 µm) which is more or less triangular in shape. The relationships among Zelleriella spp. And Nyctotherus spp. In reptiles are discussed.
