Genus TRICHIOSOMA Leach 



Trichiosoma Leach, 1817. Zool. Misc., v. 3, p. 108. 



Type-species: Tenthredo liicorum Linnaeus. Desig. by Curtis, 1825. 



A Holarctic genus with about 20 species. Adults are large and densely hairy sawflies and may 

 girdle twigs of their host plant with their powerful mandibles. This genus is in need of study. 

 Adults show extreme variation in color and external structure and a thorough study will be 

 necessary to determine the correct status of the segregates listed below.
