Navigobius dewais a sensational new species and genus of dartfish with some very firefish-like qualities. Described in 2009 from specimen collected in Kagoshima Bay, Japan,Navigobius dewais so unique that it was placed into a genus all it’s own, perhaps because of this fish’s unique similarity with dartfish of the genusPtereleotrisand the firefish of the genusNemateleotris.
The business (head) end ofNavigobiuslooks very much like a firefish, a purple firefish with a big eye. The delicately patterned finnage ofNavigobiuslooks at once like a firefish and somewhat like a lined dartfish,Ptereleotris grammicabut that ostentatious colorful lyretail is entirely unique to Dewa’s dartfish. So far only known form a tiny region in Southern Japan, and at depths between 150-300 feet, don’t expectNavigobius dewa出现在美国或欧洲礁场景anytime soon.
