A short form of Neobrachiella rostrata is found on the gills of Greenland halibut, Reinhardtius hippoglossoides, in the Gulf of St. Lawrence. Female copepods from Greenland halibut differ from females occurring on Atlantic halibut, Hippoglossus hippoglossus, in body size and shape of trunk; males differ in the specific structural details of the second antenna and maxilliped and in the presence of armed uropods and a tympanum between the second maxillae. Intraspecific variations are commonly found in females of the genus Neobrachiella but have never been reported in males.
