Chloropidae: Conioscinella zetterstedti Andersson, 1966, in earlier times identified by many authors as "C. brachyptera (Zetterstedt, 1848)" but not identical with Aphanotrigonum brachypterum (Zetterstedt, 1848). A typical species in marine dunes covered with Ammophila arenaria; Europe until Siberia and Kamchatka, North America. Mass occurrence in Barber traps among Ammopgila tussocks.
