[Microsporidiosis of the dragonfly Aeshna viridis larvae (Odonata: Aeshnidae) caused by Systenostrema alba Larsson, 1988 (Microsporida: Thelohaniidae)].
A microsporidian species producing octospores in sporophorous vesicles is found in Aeshna viridis larvae from intermittent streams situated in the vicinity of Novosibirsk City. Size of the spores measured on fresh smears was 6.9 +/- 0.09 microm x 4.1 +/- 0.08 microm (6.0-7.6 x 3.5-4.9). Each spore have single elongated nucleus and an anisofilar polar filament composed of 10-11 anterior and 10-11 posterior coils. The infection was restricted to adipose tissue. According to spore morphology the Siberian isolate can be attributed to the species Systenostrema alba described from Aeshna grandis in Sweden (Larsson, 1988). This is the first description of Microsporidia infecting Odonata from Siberia.
