The genus fusehis was erected by Wainstein in 1982 and he designated Sehilusfinlandicus Oudernans as the type species. The genus is world-wide in distribution and its species inhabit trees and shrubs. The species of this genus are partially predators and primarily pollemphagous (Muma and Denmark, 1970).

Chaudhri (1979) described 3 new species from Paid stan. The authors have described 4 new species, making a total of '7 species from Pakistan. A comprehensive key for these species along with similarity matrix and phenogram are given in the following pages.
