Abstract
This paper presents the first scientific data on the diversity of spiders (order Araneae) in the Karkaraly State National Natural Park (Karaganda Region, Kazakhstan). Field material was collected in the Kendara Valley, near of Lake Shaitankol, and at the field practice station of the E.A. Buketov Karaganda National Research University using trap lines, soil sampling, and manual collection during July and August 2025. Fifty two species of spiders were identified; 5 families and 40 species are reported for the first time for Central Kazakhstan according to non-digitized literature data and the Global Biodiversity Information Facility. The results considerably expanded the information available through GBIF on the species diversity of the order Araneae in Central Kazakhstan. Differences were identified in the species diversity recorded via the iNaturalist app and based on collections using traditional field methods. It was concluded that large-scale field studies of spiders in Central Kazakhstan are necessary, as well as the digitization and mobilization of data published in the literature through the GBIF portal.
