Diagnosis. This species is similar to L. laticeps (Schenck) from Europe. It is separated from L. laticeps by the female T2 without lineolation and the male mesoscutellm with coarse rugulae. In contrast, in L. laticeps , the female T2 lineolate on apical half and the male mesoscutellum reticulate-punctate ( Murao & Tadauchi 2007).
