In his treatment of the Scoliidae in Fedtschenko's Reise in Turkestan, De Saussure divided the genus Myrmosa into two subgenera: Myrmosa sensu stricto, and Paramyrmosa, which he defined as having “the second cubital cell [of the fore wing] trapeziform; one of its sides common with [i. e. broadly sessile on] the radial cell” and by the first abdominal segment being depressed, triangular, funnel-shaped, and not as strongly nodiform as in typical Myrmosu. In this new Paramyrmosa, Saussure includes only his new Transcaspian species, Myrmosa Radoszkowskyi, which thus becomes the genotype by monotypy.
