I have a field guide app on my phone that isn't too bad, developed by the Australian Museum and Museum Victoria. Their image of a black house spider looks like your photo and shows a chevron like pattern on the abdomen, with several arrow shapes pointing forward. Curiously there is also a mottled brown version of the black house spider.
