Gerris (Gerris) argentatus Schummel, 1832

RECORDS. Tuscany: Idoli lake, 1370 m, Monte Falterona, Stia (AR), 22.VII.2009, GM & GC leg., 1 V (F) (CCFI); Vignano lake, 600 m, Poppi (AR), 25.VI.2006, FC & GM leg., 1 M macr (CCFI).

Remarks. This is a Sibero-European species. Its distribution in several Italian regions requires further investigation. Cavanna & Carobbi (1882) published the only record for Tuscany, although we collected this uncommon species at several other sites in the region (unpublished data). This is the first record for the Park.
