Plasmodium semnopitheci is a parasite of the genus Plasmodium and subgenus Vinckeia. As in all Plasmodium species, P. semnopitheci has both vertebrate and insect hosts. P. semnopitheci was isolated from a monkey.[1]
The parasite was first described by Knowles in 1919.
The only known host of this species is the northern plains gray langur (Semnopithecus entellus).
