Iridothrips mariae Pelikan

(Figs 5, 25, 28)

Iridothrips mariae Pelikan, 1961: 64 . Described from former Czechoslovakia, this species is recorded from several European countries on the aquatic plant Typha (Pelikan 1961; Jenser 2013b). In lacking ocellar setae pair I it is almost unique among species in the Frankliniella genus-group. However, this loss is shared with two unrelated Neotropical species of Frankliniella, antennata and speciosa (Nakahara 1997). Some individuals of iridis have four pairs of ocellar setae (Mound et al. 1976), thus the genetic control of these setae among these species is possibly less rigid than usually expected. According to Manfred Ulitzka (pers. comm. 2018) the sense cones on antennal segments III and IV of mariae are always simple.
