Abstract
A checklist of 30 spider species recorded from the Tigirek State Nature Reserve (the Altai Territory) is provided, of which four species are recorded from the reserve for the first time and one is new to the Altai Mts. Also, the family Uloboridae was first recorded for the reserve.
Introduction
The Tigirek State Nature Reserve is situated in the northwestern part of the Altai Mts. Its territory lies at the altitude ranging from 500 to 2000 m a.s.l. Most of the reserve relief is middle-mountain, with dome-shaped peaks.
Special studies of the reserve's spider fauna began relatively recently. The first annotated checklist of spiders of the Tigirek Reserve was published by Trilikauskas and included 132 species (Volynkin et al., 2011). Later, the number of species was increased to 153 thanks to a series of publications by Azarkina & Trilikauskas (2012, 2013a, b; Trilikauskas, 2014). The latest paper by Fomichev [2016] already contains information on 175 spider species recorded from the territory of the Tigirek Reserve. Nevertheless, the spider fauna of the reserve remains poorly inventoried.
Methods
This paper is based on the spider material collected by the senior author, A.S. Slepenkov and A.E. Naydenov in the period of 1–13 July, 2016. The spider species recorded from the Tigirek Reserve for the first time are marked with an asterisk (*), and those that are new to the Altai Mts with two asterisks (**). The studied material has been deposited in the collection of the Institute of Systematic and Ecology of Animals SB RAS, Novosibirsk, Russia (curator: G.N. Azarkina).

COMMENTS. Males of two species, Pardosaagrestis(Westring, 1861) and P. plumipes(Thorell, 1875), can be easily distinguished by formation of first legs; males of P. plumipeshave long and dense hairs on tibiae, metatarsi and tarsi of first legs, while in P. agrestis this character is absent. Females of these two species are hardly distinguishable from each other. The only way to identify females is collect it with males (Azarkina, personal data).

Results
The spider fauna of the Tigirek State Nature Reserve is complemented by three additional species and now accounts for 180 species in 98 genera and 23 families. Even so, the araneofauna of the reserve seems to consist of more than 240 species (Fomichev, 2016).
