Righteous Catherine of Pskov, Nun-Martyr

No authoritative source (azbyka.ru, drevo-info.ru, pravenc.ru, days.pravoslavie.ru) contains information about a separate "Nun-Martyr Catherine of Pskov." The original template carried the same 2-date cluster (November 25/December 7) as Great Martyr Catherine of Alexandria (catherine) — these dates belong specifically to her. The sole captioned image is explicitly sourced as "orthodoxwiki - Catherine of Alexandria," meaning the card was originally just a copy of the Alexandrian great martyr's icon with no identity of its own. Among Russian 20th-century new martyrs there were several nuns named Catherine (e.g., Catherine Cherkasova, Catherine Konstantinova), who suffered at Butovo, but none of them is specifically connected to Pskov according to the sources found. Pending a reliable source, the card is honestly marked as unconfirmed and hidden from the calendar.
