from mountainous regions; An. maculipennis was collected mostly from plain regions; and two last species were collectedonly from mountainous areas. In contrast with the mentioned species, An. claviger, An. marterii and An. stephensi had a limited distribution. An. claviger was collected approximately in a same proportion from the plain and mountainous areas; and An. marterii, and An. stephensi were collected only from the highland areas.
