It was described by Allan Riverstone McCulloch and Edgar Ravenswood Waite in 1916. Under the synonym Norfolkia lairdi it was the type species of Fowler's new genus.

Norfolkia thomasi, known commonly as the Thomas' triplefin, is a species of triplefin blenny in the genus Norfolkia. It was described by Gilbert Percy Whitley in 1964, naming it in honour of Leonard Rees Thomas who organised the Australian Museum's 1962 Swain Reefs Expedition. The hemispherical eggs of the Thomas' triplefin are covered in sticky threads that help anchor them in the algae on their nesting sites. This adaption helps insure the safety of the eggs. One the eggs hatch the larvae that emerge are planktonic and they stick to shallow waters near the shore. The matured Thomas' triplefin then ventures out into the coral reef and intertidal pools. This species is found in the western Pacific Ocean from the Ryukyu Islands to the Tuamoto Archipelago, in Australia it is distributed from the northern Great Barrier Reef south to Byron Bay, New South Wales.

Kulbicki of L'Office de la Recherche Scientifique et Technique d’Outre-Mer in Nouméa, who collected type in New Caledonia, in its specific name. Kulbicki's triplefin is found in the southwestern Pacific Ocean from Queensland, Australia across the central Pacific to the Samoa, where it is found on rocky and coral reefs down to 15 metres (49 ft) in depth.
