Parastylotermes

Parastylotermes is a genus that holds five extinct species of termite that resided in Europe, India, and North America. The genus was first described by Thomas E. Snyder and Alfred E. Emerson in 1949. The first species to be described, P. robustus, was described by Baron Kurt von Rosen in 1913, but he was unsure about which genus to classify the species in. This species, which is known from three imagos and four separate wings, was placed into its current genus in 1949. The classification of P. washingtonensis occurred similarly to that of P. robustus, although Snyder and Emerson, who used it as the type species for the Parastylotermes genus, only reclassified it once.

The third species to be described was P. frazieri, which was discovered by T. H. McCulloh in 1954. The species was described from one wing, which measured a length of .39 inches before the tip of the wing was lost. P. krishnai is the second species within this genus to be described from adult specimens, which are encased separately in amber and kept in the Birbal Sahni Institute of Palaeobotany of Lucknow, India and the American Museum of Natural History. Michael S. Engel and David Grimaldi described this species in 2011. The last species from North America to be described was P. calico, which was described by William D. Pierce in 1958. The specimen used to describe this species is a portion of a wing, most likely a forewing, but there are limited differences between the wing of this species and those of P. washingtonensis.
