Chorology.

Stenus fuscicornis is widely distributed throughout most of Europe and the Mediterranean including the Maghreb countries and Turkey. The first record for Iran was published by Puthz (2012a: 312). In Iran, we discovered the species in a relatively small area in the western Elburz and the Talish Mountains (Fig. 14 ). Unlike most members of the Stenus hopffgarteni species group which are European endemics, Stenus fuscicornis is the only representative of the species group in the Middle East. In Iran, the species obviously reaches its eastern limit of distribution.

Biogeographical characterization.

Stenus fuscicornis is a Holomediterranean species according to Puthz (2012a: 312).
