Abstract

Five new species and one new genus of Serphitidae microhymenoptera are described from Upper Cretaceous (Campanian) amber originating at the Grassy Lake locality in Alberta, Canada. New taxa include Serphites hynemanisp.n., Serphites bruesisp.n., Serphites kuzminaesp.n., Serphites pygmaeussp.n. and Jubaserphites ethanigen. et sp.n. Topotype material for the type species of Serphites, Serphites paradoxus Brues is re‐illustrated and redescribed in greater detail, clarifying the characteristics of the species for comparison with the numerous serphitids that have been described subsequent to the work of Brues. We provide the first comprehensive report of known serphitid specimens in Canadian amber, draw comparisons with taxa in other Cretaceous deposits, and comment upon the palaeoecological connotations of the relatively diverse and morphologically disparate Canadian serphitid assemblage.
