【Abstract】 This paper deals with two new species of Plasodium found in two species of snake (Natrix stolata, Bungarus multicinctus) from the "new star" farm of Hainan Province, P. R. China.Plasmodium (Ophidiella) natrixi, sp. nov.This new species was found from a snake (Natrix stolata) in the August of 1994, Hainan province. The duration of schizogony in the blood was unknown and develop unsynchronous. the youngest forms can be found in any position of the erythrocyte, it tends to be round or oval and one pigment granule appears at the nucleus sides of the parasite. the cytoplasm of erythrocyte infected by the late stages is pale. Four to twelve merozoites are produced in a mature schizont with a little cytoplasm. One or two dark brown pigment granules appear in the cytoplasm. Both microand macrogametocytes are the spheral form or elongated.Type host: Natrix stolata Location in host: the erythrocytes Locality ; the "new star "farm(18°90′N, 110°E)in Hainan province Plasmodium (Ophidiella) multicincti, sp. nov.This new species was found from anther snake (Bungarus multicinctus)in the third area of same farm, in the July 29, 1994. The distinctive characters of the parasite is:①the erythrocytes infected the asexual and sexual form are fragile, and a lot of these schizonts or gametocytes are free in the plasma. ②one end of the asexual and sexual bodies can be found in the erythrocyte, while another is by apparently free and outside the host cell. ③ six to twelve merozoites were seen in a mature schizont. ④ the pigment of macrogametocytes clumps into a linear form, and they are distributed along edge of the parasite when they are found in the erythrocyte, the number of the pigment is not distinguished, the parasites are free in the plasma, more than 20 pigment granules are scattered throughout the cytoplasm.Type host: Bungarus multicinctus Location in host:the erythrocytes Locality: the third area of "new star" farm(18°90′ N, 110°E)in Hainan更多还原
