The last image shows that upper parafacials really with a row of hairs.
But I think that my first identification requires some correction: there are 2 European species with such hairs and your female is another one: F. leucosticta
The common difference is that leucosticta has abdominal tergites with triple spots, whereas in pusio abdomen is evenly glossy black. These spots are probably visible on the first image, but difficult to be sure. But we could see that fronto-orbital plates are dusted (mostly glossy in female pusio) and scutum with 3 thin brownish vittae (indistinct in pusio). So, F. leucosticta
