Abstract

A female of Promicrodispus altaicus Khaustov sp. nov. (Acari: Heterostigmata: Microdispidae) is described from the forest litter sample collected from vicinity of the Teletskoye Lake in Altai Republic of Russia. The new species is very similar to P. pumilis (Sevastianov), but it can be distinguished by the presence of setae ps2 and lacking of seta s on tibiotarsus of leg I. Using of SEM microscopy revealed previously unknown structure in gnathosoma of the new species. A key to the species of Promicrodispus is also provided.
