Mockford, in his handbook of Canadian and U.S. Psocoptera (1993) listed three described species in the genus: L. coloradensis, L. lugens, and L. sparsa. He noted that many eastern species are undescribed.

Mockford (1993) gave these key traits of the genus:

"Rs and M in hindwing joined by a crossvein. Distal piece of subgenital plate transverse, flat or slightly depressed on hind margin."
