SPIDERS (ARACHNIDA: ARANEI) OF FIVE FOREST HABITATS OF THE POLISSYA NATURE RESERVE (ZHYTOMYR AREA, UKRAINE)

Abstract

The Polissya Nature Reserve is located in the zone of mixed forests in the physical geographic region of Zhytomyr Polissya (Zhytomyr region, Ukraine). The first data on the spiders of the reserve were obtained by Guryanova V. She gave a list of 66 species from five forest and one swamp coenoses of the Perga forestry. Later, K. Evtushenko and L. Kobzar in an abstract reported on the discovery of 51 species from 14 families from five forest coenoses of the Selezivka Forestry. The list of spiders of the reserve was supplemented by 21 species. Currently, a list of all detected species and their coenotic distribution is provided. The data were obtained on the material collected by the method of soil traps in a pine lichen forest, pine green moss forest, pine-birch blueberry forest, pine-birch molinia forest and birch-oak-elm forest. The material consisted of 866 adult specimens of spiders. Most of the detected species live on the surface of the soil or in the litter. These are common forest species that prefer moist and shaded conditions. Only a few species are rare for Ukrainian Polissya: Arctosa lutetiana (Simon, 1876) (known from the Shatsk National Nature Park), Mustelicosa dimidiata (Thorell, 1875) (recorded in the v. Kozyn near Kyiv) and Zora sp. 1 and Zora sp. 2 – not identified to species close to Z. manicata Simon, 1878. The total list of spiders of the Polissya Nature Reserve consisted of 87 species from 17 families. Infection of spiders of the Liocranidae family with larvae of the fly Ogcodes sp. (Diptera: Acroceridae) was recorded for the first time. Two females of the spider Agroeca proxima (O. P.-Cambridge, 1871) were infected. Females were collected in pine lichen forest and birch-oak-elm forest. Larvae are localized inside the abdomen of spiders near the epigastric slit. The article contains photos of the location of the fly larvae inside the spider and the appearance of the larvae.
