Chorology.

Stenus maculiger is widely distributed in the Northeast Mediterranean and eastern Europe eastwards to South Russia and Iran. The first records for Iran were published from Ghaemshahr in Mazandaran ( Ghahari et al. 2009b: 1964) and Jangal-e Abr in the Semnan Province ( Hadian et al. 2011: 4). However, we doubt these records, because we were unable to find this species in the South Caspian mountains. Our collections in Northwest Iran must be regarded as the first confirmed country records (Fig. 13 ). The locality in the Ardabil Province moreover constitutes the easternmost collecting site of the species.

Biogeographical characterization.

Judging from the distribution pattern, Stenus maculiger belongs to the expansive Pontomediterranean faunal element.
