Nine new goby species and four new genera

By Leonard Ho - Posted May 16, 2016 09:00 AM
Thanks to advances in submersible technology, recent exploration of mesophotic (AKA twilight zone) Caribbean reefs have yielded nine new deep-water goby species and a reclassification of the Nes subgroup of gobies.

The above gobies are the nine newly described species by a team from the Smithsonian Institution’s Deep Reef Observation Project published in in the Zoological Journal of the Linnean Society.  All the gobies hail from deepwater, mesophotic Caribbean reefs.  The research team documented and captured specimens using manned submersibles such as the Johnson Sea-Link I and II submersibles and the Curasub.  It is technology like these that has opened the doors to exploring the alien world of deep reefs.

In addition to the new gobies, the research team also revamped the family tree by adding four new genera to the Nes goby subgroup.  The new genera were added because shallow water gobies (once classified as congenors) were so distantly related to their twilight-zone gobies that these gobies warranted genera of their own.

With the addition of these nine gobies, the Nes subgroup of gobies now contains 38 species in the genera: Carrigobius gen. nov., Chriolepis, Eleotrica, Gobulus, Gymneleotris, Nes, Paedovaricus gen. nov., Pinnichthys gen. nov., Psilotris, and Varicus.
