A new Hawaiian deepwater anthias named after President Obama

Tosanoides obama is a new deepwater basslet/anthias from the Northwestern Hawaiian Islands. It was named after Obama, who in 2016 expanded the Papahānaumokuākea Marine National Monument to become the world's largest protected marine reserve.

Tosanoides obama is described from two specimens collected at a depth of 90–92 meters off Kure Atoll and Pearl and Hermes Atoll, Northwestern Hawaiian Islands, part of the protected Papahānaumokuākea Marine National Monument.

The new basslet was discovered by NOAA scientists exploring the mesophotic reefs of Hawaii on June 5, 2016.  Initially, i twas thought be a juvenile of Pseudanthias thompsoni, but analysis revealed that the fish is a new species of the genus Tosanoides.  T. obama is only the third of the genus.

In August 2016, President Obama expanded the size of Papahanaumokuakea Marine National Monument to 582,578 square miles. This is more than twice the area of Texas, six times the size of the UK, making it the world's largest marine reserve ... and the only known home to T. obama.

The new species is described in ZooKeys.
