Heteroclinus kuiteri, or Kuiters weedfish,[2] is a species of clinid native to the Indian Ocean coast of Australia.

[4] The specific epithet "kuiteri" refers to Rudie Kuiter, who is credited by the authors with providing a substantial amount of material on other Australian clinids.

[4] Male Heteroclinus kuiteri can reach a maximum length of 6 centimetres (2.4 in) SL.

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.

[4] 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.
