Etymology: Siphamia: A Swazi word, siphama, for a fish; randalli: This species is named randalli in honour of Dr. John E. Randall of Honolulu, Hawai’i, for his numerous and noteworthy contributions to our knowledge of reef fish taxonomy. Jack, as he is known to friends and colleagues, is a genuine inspiration to everyone in the field of ichthyology. Moreover, Dr. Randall’s Siphamia collections at BPBM and specimen photographs, including this species, have formed an essential part of our revision (Ref. 90035).
