Sitticus terebratus is a spider species known from a few localities in Poland. The records refer to the south Poland - in the West Beskid and the Orawa-Nowy Targ Basin, as well as in the north-eastern part of the country. The study revealed 13 new localities of this species ranging from the Babia Góra Mts to Bieszczady Mts. All sites of S. terebratus are synanthropic but observations indicate that the species is very rare and it may be endangered both in Poland and in Europe.
