Hydraena (Hydraena) gattolliati Jäch & Delgado, 2010

Material examined. Loc. 4: 1 ♁.

Notes. New record for Oman. The species was described from the wadi Wurayah, in the northeastern UAE, which is also the type locality of Ochthebius wuraya Jäch & Delgado, 2010 . A third species of Hydraenidae was found in the same locality, Hydraena putearius Jäch & Díaz, 2000 (JÄCH & DELGADO 2010). It is remarkable that the same three species were found in our locality 4 (Figs 5, 6), but with the addition of three new species, one Hydraena and two Ochthebius (see below).
