In his Fig. 215, Schmitz (1956) illustrated an extra pair of dorsolateral glands behind abdominal tergite 5 of the female. These are associated with the modified T6, which is greatly shortened but expanded laterally and disrupted in the middle ( Fig. 22 ). These glands are not the laterally displaced dorsal abdominal glands but a novel development peculiar to this genus. The normal, but unusually large, DAGs are shown in Fig. 22 . They are restricted to the female. Male hypopygium as Fig. 21 and hind tibia as Fig. 23 . The species is Holarctic in distribution.
