SYNOPSIS. The sporozoite of Lankesteria culicis was studied by light and electron microscopy, after excystation in the intestine of Aedes aegypti 1st stage larvae. The sporozoite was 9.5–10.0 μ long with a blunt anterior end and a tapered posterior region. The organism was enclosed by a typical pellicle consisting of an outer and an inner membrane with underlying subpellicular microtubules. The anterior end had a conoid with 2 associated rings, a polar ring which served as a termination of the subpellicular microtubules and a flask‐shaped structure situated internal and posterior to the conoid. A micropyle consisting of a collar formed from the inner membrane and lacking an invagination of the outer membrane was present near the anterior end of the parasite. The nucleus was centrally located and had a peripheral concentration of chromatin and a central nucleolus. One or more mitochondria were observed in the vicinity of the nucleus.
