Dimorphopterus blissoides (Hemiptera: Heteroptera: Blissidae): recent spreading of a neonative species in the Pannonian Basin

Dimorphopterus blissoides (Baerensprung, 1859) (Hemiptera: Heteroptera: Blissidae) is recorded for the first time from Slovakia and Iran. We provide also additional records of D. blissoides from Bulgaria, Croatia, Greece, Hungary and Romania, and review the distribution of the species. The species is currently spreading in the Pannonian Basin, reaching its northern distribution limit in southern Slovakia. We confirm its development on Phragmites australis, with preference to the loose outer leaf sheaths of the galls of Lipara lucens Meigen, 1830 (Diptera: Chloropidae), where the specimens develop during summer as well as hibernate during winter.
