Historical synonyms:
Beneckea nigripulchritudo Baumann, Baumann, Mandel & Allen 1971.
Gram-negative, straight rods, motile. Not presenting lateral flagella on solid media.  
Not swarming on complex media. No luminescence.
Can grow in nutrient broth with: 1% NaCl & 6% NaCl. No growth in 0% NaCl, 8%
NaCl, 10% NaCl & 12% NaCl. Growth temperature 30 ºC, no growth at  4 ºC or 35 ºC.
Can be differentiated from other Vibrio species by its formation of striking blue-black
colonies (2 days incubation on basal medium agar with 0.2 % glycerol).
Isolated from seawater of the coast of Hawaii. Sensible to O/129 vibriostatic agent (10 & 150 µg).
Unknown.
