Prostylotermes is a genus that holds one species of extinct termite known as Prostylotermes kamboja. The genus and its single species are known from one male, the paratype used to help confirm the description of the species, and one female, the holotype, found encased in amber in India. Both individuals were found in the same piece of amber, which is kept in the Birbal Sahni Institute of Palaeobotany in Lucknow, India. The fossils were first studied and described by Michael S. Engel and David Grimaldi and their findings were published in the ZooKeys online journal in 2011.

The two specimens are remarkably well preserved, with only a few parts of the female being lost. Both the male and female are brown in color and do not hold wings, a common trait of breeding pairs. The female is .20 inches in length while the male is .15 inches in length and both have compound eyes and short cerci on the end of the body. Where the female is missing part of her abdomen, two formed eggs can be seen.
