Spider and Fly

The same friend in Equatorial Guinea whose picture of a lightning I posted yesterday also took this picture. This spider lives on his desk. He waited several days for the spider to catch a fly and then took this picture:

Anyone venture to ID the species of the spider and/or the fly?

Some years ago a colleague who was an avid fly tying fisherman died. As part of his memorial ceremony, our advisor (we were both DeVore's students) put on display a display box of his flies. One of the flies had been captured and tied up by a spider. The spider was still in the box, having died of starvation, I suppose.
