 The blennies are sometimes uniformly brown in colour, but can also possess a white-brown mottled band from the eyes to the tail, or approximately 8 dark brown bands along the body (most frequently shown in females), which become darker on the back.Hoese and Rennis describe "H. kuiteri" as being most closely related to its sister taxon "H. adelaidae" and "H. macrophthalmus", with all three species possessing a broad membrane connecting the anal ray to the caudal peduncle.
