This species included 0.45% of the total larvae collected; and like An. turkhodi, it was collected exclusively from mountainous areas including the villages of Mahroo, Eastern Zez, Eastern Zalaghi, Pishkuh-Zalaghi and Fersesh. This Anopheles was found often in permanent waters (75%) and current waters (58.3%) with or without plants. This study includes 12 larval nests; and introduces An. d’thali as a mosquito that is heliophilia; and prefers clean waters for egg-laying. Seventy percent of natural larval nests were in the sides of rivers; but artificial larval nests were only plots of rice cultivations (Table 3). Larvae of this
Anopheles were caught along with all other Anopheles species of the region except An. apoci.
