Sahlberg’s Aquatic Weevil (Echinocnemus sahlbergi)

Sahlberg’s Aquatic Weevil was described in 1911; it is known exclusively from the type series of four specimens that were collected from the Ayalon River in Tel Aviv, Israel, which now is almost completely channeled and probably quite polluted due to agriculture.

The species has not been found since its description and is thus very likely already extinct. [1]
