The aim of the present study was to verify the occurrence of hemogregarines in the colubrid snake Thamnodynastes lanei from the eastern Amazon region of Brazil. Intraerythrocytic gamonts with mean dimensions of 14.8 ± 1.8 × 4.0 ± 0.7 μm and encapsulated gamonts with mean dimensions of 15.3 ± 1.1 × 4.8 ± 0.5 μm were observed. Through morphological and molecular data based on the partial 18S rDNA gene, the parasite was identified as Hepatozoon cevapii, originally described in the viperid snake Crotalus durissus terrificus from the southeast region of Brazil. Thus, the findings of the present study extend the geographic range of H. cevapii and provide novel Hepatozoon–snake associations.
