Looks a very good match to this genus on CNM, so I have taken the liberty of adding it to the ALCW list. Watched it for several minutes seemingly dithering about which of two holes about 30 cm apart it wanted to drag this spider into. They'd been excavated in sand between our house footing wall and the first course of dry-laid bricks in the path. After a lot of running back and forth, during which the presumably already paralysed spider just sat still, it eventually bypassed the nearer hole and dragged it into the second one. I'll put up a separate sighting for the spider.
