Abstract

Eimeria jirkamoraveci check for this species in other resources sp. n. is described from faeces of two specimens of the toad-headed, side-necked turtle Batrachemys heliostemma check for this species in other resources collected at Iquitos in Peru. Oocysts are ovoid to almost spherical, 10.6 (8-12) ' 8.9 (7-10) μm, without micropyle, polar granule and oocyst residuum. One conically stretched end and three blunt conical tubercles at the opposite end of oocyst give it mitra-like appearance. Sporocysts are elongated, ellipsoidal, 7.2 (6-8) ' 4.1 (4-4.5) μm, with a small, knob-like Stieda body and sporocyst residuum composed of fine granules. To avoid possible conspecificity, the described new species is thoroughly compared with the most similar coccidium, E. mitraria, collected from its type host, Chinemys reevesii check for this species in other resources .
