The morphology of the adults, egg, larva and pupa of Anopheles persiensis Linton, Sedaghat & Harbach, an Iranian member of the Holarctic Maculipennis Group, was studied and compared with the morphology of the closely related and sympatric A. maculipennis Meigen. Anopheles persiensis was formally recognized based on DNA evidence and egg morphology. The fourth member of the group, Anopheles persiensis, is described in detail and the egg illustrated using scanning electron microscopy
