[The occurrence of unusual chaetotaxy in III--IV instar larvae of blood-sucking mosquitoes from the genus Aedes].

Larval material on the Aedes mosquitoes of the complex punctor (Far East expeditions in 1976-1980) was compared to material preserved in the Zoological Institute, Academy of Sciences of Russia. 6 types of aberrations (presence-absence of accessory hairs on the surface of siphon, their parity, etc.) were found. The individual variability and absence of diagnostic validity of these accessory hairs are suggested.
