Anopheles (Anopheles) sinensis and An. (Ano) lesteri are members of An. hyrcanus group, and are considered potential malaria vectors in Japan. To determine their habitats and geographical distribution, extensive mosquito collections were conducted from different islands and localities in Japan (2002-2003, from Okinawa to Hokkaido), and they yielded primarily An. sinensis, An. lesteri and An. hyrcanus group species. Both morphological and molecular techniques were used to identify mosquito specimens collected. Mosquito immatures from natural habitats were reared to preserve larval/pupal exuviae and adults for morphological identification and molecular confirmation using ITS2 and COI. Collection habitats included irrigated rice fields, ditches, temporary pools, vegetable irrigated fields, streams and riverbanks.
