Prognathodes basabei, a new of deep-water Hawaiian butterflyfish

By Leonard Ho - Posted Sep 09, 2016 09:00 AM
Prognathodes basabei is a lovely new Chaetodontid species observed in Northwestern Hawaii at depths ranging from 45 to 187m (150 to 600+ feet).

Prognathodes basabei calls Papahānaumokuākea Marine National Monument - the world's largest marine protected area - its home.  It shares habitat with Hawaiian deep-water endemics such as the Bodianus sanguineus wrasse/hogfish and Odontanthias fuscipinnis anthias, as seen in the photo below where P.basabei is seen swimming upside-down under a reef overhang along with this anthias.

Prognathodes basabei is named "in honor of Peter K. Basabe, long-time diver, aquarium fish collector and resident of Kona, Hawai‘i, both for his role in the collection of the first specimen of this new species in 1998, and more generally for his extensive contributions and assistance to many researchers (especially the authors) in the ichthyological community."

The new butterflyfish is most closely related to another rare deep-water butterflyfish, Prognathodes gueizi as well as an yet undescribed Prognathodes sp. from Palau.  It is described in ZooKeys open access paper.
