ANAS

ANAS S.p.A. (formerly an acronym for Azienda Nazionale Autonoma delle Strade, ) is an Italian government-owned company deputed to the construction and maintenance of Italian motorways and state highways under the control of Italian Ministry of Infrastructure and Transport.

Anas is a genus of dabbling ducks. It includes mallards, wigeons, teals, pintails and shovelers in a number of subgenera. Some authorities prefer to elevate the subgenera to genus rank. Indeed, as the moa-nalos are very close to this clade and may have evolved later than some of these lineages, it is rather the absence of a thorough review than lack of necessity that this genus is rather over-lumped. However, there are 42 species verified by ITIS, and the IUCN recognizes 46 species.
