Sibianor larae Logunov, 2000 M a t e r i a l. 1 Ơ, Volyn Area, Shatsky National Nature Park, Shatsk District, Svityaz Vil., 51°28'33'' N, 23°47'37'' E, sphagnum bog, pitfall, 29.05.1990 (Evtushenko); 1 ♀, Chernyhiv Area, Ripky district, Grybova Rudnya Vil., 51°56'54'' N, 31°08'10'' E, swamped pine-birch forest, on the sphagnum hummock, 31.06.1985 (Evtushenko). Salticid spider S. larae is a Palearctic species (Platnick, 2014). In the first description D. Logunov (2000) characterized this species as Euro-Siberian temperate species distributed in Fennoscandia and Estonia, through the middle Urals and Siberia, eastward to Sakhalin (Logunov, 2000). Also S. larae was registered in Belgium (Keer van et al., 2010), Sweden (Logunov, 2000; Almquist, 2006), Germany (Keer van et al., 2010; Staudt, 2011), Netherlands (Vogels, 2012). Notably, the specimens of the species were mainly found in dry open biotopes: semi-shrubby meadow, low-lying meadow, sheep-grazed wet heath, dry heath etc. (Logunov, 2000; Vogels 2012). Both specimens were found on sphagnum of the wet bog and in the shaded pine-birch forest. Although the species habitat is vast, the finds of S. larae specimens are rare and small in numbers (Logunov, 2000; Vogels, 2012). In Belgium, Germany and Netherlands S. larae was characterized as a rare species (Vogels, 2012)., Published as part of Evtushenko, K.

Sibianor tantulus (Simon, 1868) M a t e r i a l. 1 Ơ, 1 ♀, Chernyhiv Area, Novgorod-Siverskyi Town, 52°00'27'' N, 33°17'57'' E, on the sloping right bank of the Desna River, pitfall, 5.06.1989 (Evtushenko). Salticid species S. tantulus has a Trans-Palearctic temperate range; from France, through C. Europe, the middle Urals and C. Siberia, east to Magadan Area, south to Tuva and C. Mongolia (Logunov, 2000). In N. Osetiya S. tantulus specimens habitats are in steppe and young oak forests and steppe meadows (Logunov, 2000). Our specimens were collected in dry birch forest with meadow grasses. As in case of S. larae, distribution of S. tantulus is very wide but its finds in Palearctic are small in numbers (Logunov, 2000). In the fauna of Ukraine S. larae and S. tantulus can be characterized as very rare species, therefore further research is needed for their finding and protection. I support Joost Vogels’ (2012) recommendation for arachnologists to verify their own and/or museum collections for clarification of S. aurocinctus, S. larae and S. tantulus distribution., Published as part of Evtushenko, K.

Різноманітність та специфічність видового складу павуків (Aranei) можна використовувати як індикаційні показники стану природних екосистем. Для вивчення структури угруповань павуків приґрунтового ярусу на території Шацького національного природного парку (Волинська область, Україна) методом ґрунтових пасток досліджували видовий склад та кількісне співвідношення павуків соснового, мішаного, дубово-грабового лісів і сфагнового болота. Зареєстровано 90 видів павуків із 15 родин. Установлено, що всі біотопи характеризуються своїми оригінальними угрупованнями павуків. Отримані дані слід ураховувати під час проведення природоохоронних заходів на території парку. A variety and specificity of species structure of spiders (Aranei) can be used as indicators of a natural ecosystems condition. The species structure and a quantitative ratio of spiders of pine, mixed, oak-hornbeam woods and a sphagnum bog was investigated with the method of soil traps for studying the structure of ground spiders communities on the territory of Shatsky National Nature Park (Volyn region, Ukraine). A total of 90 species of spiders from 15 families are registered. It is established that all biotopes are characterized by the special communities of spiders. The obtained data have to be considered when carrying out nature protection actions in the park territory. Роботу виконано у відділі акарології ІЗ ім. І. І. Шмальгаузена НАН України
