In Saudi Arabia this is one of the more common members of Lepisiota. It forms large polygynous colonies. (Collingwood, 1985)
This species is similar to Lepisiota gracilicornis in the long appendages but differs in sculpture. The propodeum and gaster are faintly sculptured with a dull shine instead of being completely brilliant. (Collingwood, 1985)
This beautiful variety is distinct from all others in having a silky gaster. It belongs to the bipartita group, including Lepisiota sericea from Hindustan. However, the shape of the head approaches that of Lepisiota frauenfeldi aegyptiaca. (Finzi, 1936)
