Trialeurodes vaporariorum
Are attached to the underside of the leaf and do not move. The end of the fourth instar is called a pupa. The pupal stage is the most important for determining whitefly species identification. Greenhouse whitefly pupae are oval and have vertical sides, giving the pupa a cakelike appearance from the side. Along the perimeter of the upper surface is a fringe of filaments and relatively large wax filaments project above the upper surface of the body. The greenhouse whitefly can complete one generation in 21 to 26 days at 81°F.
Very large populations of whiteflies cause stunting of plant growth, and leaves may senesce and die.

Definitely whitefly pupae - Tetraleurodes sp. Not Trialeurodes vaporariorum nor Aleurocanthus sp.
Here are a couple of images for whitefly pupae. Many whitefly pupae are light coloured (yellowish); however, quite a few are black (often called blackfly). Note that the images below are from different hosts (and almost certainly different species).
Here are some links to images of:

I would lean toward a species of gall
Some kind of whitefly
