Specimens examined. Four females, vicinity of Uspenka, Tyumen Province, Russia, 57°04'N, 65°04'E, 20 May, 2020, O. Joharchi coll., in the nest of Myrmica sp. ( Hymenoptera: Formicidae).
Remarks. Sheals (1962) described Cosmolaelaps rectangularis as a new species from Patagonia, Argentina, on the basis of one female specimen collected on an unspecified substrate. Subsequently, Costa (1968) redescribed the species based on female specimens and described the male of this species for the first time from Israel. This species has been recorded from North America, Europe and Asia from soil-litter or ant nests and is now recorded in Russia for the first time, from a nest of Myrmica sp .. Our newly collected material agrees very well with the redescription given by Costa (1968). This species can be readily recognised by the 39 pairs of spatulate-mucronate-tricarinate dorsal setae.
