I’m pretty sure T. atrica was moved to the Eratigena genus. With that being said I think you are right about it being female and you are also probably correct about it being Eratigena atrica. The three Giant House Spiders in the Eratigena genus look very similar to one another and are hard to differentiate them sometimes. If atricas are commonly found around Czech Republic than its a safe bet that you are correct on your identification.
Tegenaria atrica, female?
