Chorology.

Stenus picipes is widespread in the temperate West Palaearctic as far east as western Russia, Anatolia, the Levant (Lebanon, Jordan, Syria), and Iran. The records from the northwestern Zagros Mountains ( Puthz 2010: 61), the first for Iran, mark the southeastern distributional limit of this species (Fig. 22 ). The specimens from Iran belong to the type form Stenus picipes picipes , which differs from Stenus picipes brevipennis Thomson, 1851 by broader elytra with well developed humeral angels. These sympatrical morphs are formally treated as subspecies in recent catalogues ( Schülke and Smetana 2015: 835, 836) and key books ( Puthz 2012a: 309).

Biogeographical characterization.

The wide area of distribution of Stenus picipes can not be attributed to particular Pleistocene refugia of the arboreal, which is why no biogeographical assigning is possible for this West Palaearctic species.
