[2 new species of microsporidians (Protozoa, Microsporidia) from mosquitoes of the family Chironomidae].
Two new species of microsporidians are described from the mosquitoes of the genus Chironomus collected in water bodies of the north-eastern USSR. Bacillidium chironomi sp. n. injuring the adipose tissue of the fourth stage larvae of Chironomus dorsalis Mg. has rod-shaped spores 15 (11 to 19) x 0.7 (0.6 to 0.9) mu in size. Duboscqia chironomi sp. n. injures the adipose tissue of the fourth stage larvae of Chironomus plumosus L. Fresh spores of this species are egg-shaped, 6.2 (5.8 to 6.5) x 3.8 (3.6 to 4.0) mu in size. When stained according to the Romanovsky-Gimza method the spores are 5.4 (4.9 to 5.8) x 3.8 (3.6 to 4.1) mu in size. Some peculiarities of the nuclei fission in the sporants of Duboscqia chironomi sp. n., are discussed.
