Content
Workers of reddish-red color have a length from several mm (from 1.7 mm for minima and 5 mm for medium-sized workers) to one cm (for large soldiers ), blind ( facet eyes and ocelli are developed only in the caste of males). Winged males are tan, up to 25 mm long (including 13 mm abdomen). The uterus is large, with a body length of up to 4 cm (including a 25 mm abdomen). The sides of the soldiers' heads are almost parallel to each other. The antennae of workers and females are 11-segmented (males have 13-segmented) [1] . The males are so different from other ants that the Swedish naturalist Karl Linney first described males of the species Dorylus helvolus (Linnaeus, 1764) as Vespa helvola Linnaeus, 1764 , and the French biologist Jean Baptiste Lamarck described them as wasps Mutilla dorylus Lamarck, 1817 [ 2] [3] .
The species belongs to the nominative subgenus Dorylus ss Shuckard, 1840 (species group helvolus- group) and was first described only by males (Linnaeus, 1764) [4] . Workers were later described (Linnaeus, 1767) [5] . The uterus was described only in 1888 by the Italian worldmecologist Carl Emery [6] . The genus Dorylus was included in 1793 by the Danish entomologist Johann Fabricius ( Fabricius , 1793) [7] [2] .
