More Info


Known only from the tidal lower freshwater reaches of the Daintree River, upstream from Daintree, Queensland. 
The type specimens were collected from a a broad shallow bank on the southern side of the Daintree River, on a coarse sand and gravel area with fallen leaves and open shells of freshwater bivalve molluscs. This riverine environment is flowing, clear and fresh (being about five or six kilometres upstream from the brackish zone), but is subject to tidal influence, with about a 75cm rise and fall.


Dorsal fin 64-68; Anal fin 48-52; Lateral-line scales 87-97, median 94; Abdominal vertebrae 10; Total vertebrae 35-36.
Body depth 2.35-2.70 in SL; HL 4.25-4.85 in SL; eye diameter 6.90-8.25 in HL; stout papillae (not long slender cirri) on anterior edge of snout and ventral edge of head (visible from above on ocular side); scales on blind side of head replaced by cirri anterior to region just posterior to rear of jaws; straight lateral line midlaterally on both sides, forming three branches on ocular side of head: ventral preopercular branch, vertical dorsal branch nearly to base of dorsal fin, and short horizontal continuation of main lateral line; distinct free fleshy sheath on blind side, extending over front half of lower jaw, including lower lip and sometimes part of upper lip when mouth fully closed.


Ocular side with about 22-26 irregular, mostly discontinuous, transverse brown bands slightly wider than pale interspaces, and three longitudinal rows of 5-6 large diffuse dark brown spots.


Gut contents included fragments of insect larvae and numerous sand grains.


The species is named for Alf Hogan, Fisheries Biologist, Queensland Department of Primary Industries and Fisheries Research Station, at Walkamin, Queensland. Alf has made a major contribution to the understanding of freshwater fishes of north Queensland over the last 30 years. He has added many rare and poorly-known fishes to museum collections and his electrofishing skills were invaluable in the capture of type material of this species.
