The bluelashed butterflyfish has a body which is yellow with a black patch surrounded by a blue circle below the dorsal fin and two curved blue lines above the belly. Its vertical black eyestripe is flanked by two blue lines.{{cite web | author1 = Dianne J. Bray | author2 = Audrey S. Thompson | name-list-style = amp | title = Chaetodon bennetti | work = Fishes of Australia | accessdate = 11 December 2020 | url = https://fishesofaustralia.net.au/home/species/2377 | publisher = Museums Victoria }} The dorsal fin contains 13–14 spines and 15–17 soft rays while the anal fin has 3 spines and 14–16 soft rays. This species attains a maximum total length of {{convert|20|cm|in}}.
Distribution
The bluelashed butterflyfish has a wide Indo-Pacific range. In the eastern Indian Ocean they are found along the eastern coast of Africa from Somalia to South Africa and across the Indian Ocean as far north as India and Sri Lanka and into the Pacific Ocean where they extend as far north as Kashiwa-jima in southern Japan, south to Lord Howe Island and east to Mangarava in French Polynesia. In Australia this species occurs on the Indian Ocean territories of the Cocos (Keeling) Islands and Christmas Island. In Western Australia it is found at the Rowley Shoals and Scott Reef. They are also found at the Ashmore Reef in the Timor Sea, the northern Great Barrier Reef in Queensland south to Moreton Bay,
Habitat and biology
Systematics
The bluelashed butterflyfish was first formally described in 1831 by the French anatomist Georges Cuvier (1769–1832).{{Cof genus | genus = Chaetodon | access-date = 11 December 2020}} The specific name honours the English naturalist Edward Turner Bennett (1797–1836) who had the type specimen of this species shown to Cuvier.{{cite web | url = http://www.etyfish.org/acanthuriformes1/ | title =Order ACANTHURIFORMES (part 1): Families LOBOTIDAE, POMACANTHIDAE, DREPANEIDAE and CHAETODONTIDAE | work = The ETYFish Project Fish Name Etymology Database | accessdate = 11 December 2020 | date = 21 July 2020 | author1 = Christopher Scharpf | author2 = Kenneth J.

Like the other butterflyfishes with angular yellow bodies with black eyestripes and, except for this species which is regarded as the most basal of them, a single differently-colored patch, it belongs in the subgenus Tetrachaetodon. Among this group it seems to be the most basal living species. If Chaetodon is split up, this subgenus would be placed in Megaprotodon.{{cite journal | author1 = Fessler, Jennifer L. | author2 = Westneat, Mark W | year = 2007 | title = Molecular phylogenetics of the butterflyfishes (Chaetodontidae): Taxonomy and biogeography of a global coral reef fish family | journal = Molecular Phylogenetics and Evolution | volume = 45 | issue = 1 | pages = 50–68 | doi = 10.1016/j.ympev.2007.05.018| pmid = 17625921 | bibcode = 2007MolPE..45...50F }}{{cite journal | author1 = Hsu, Kui-Ching | author2 = Chen, Jeng-Ping | author3 = Shao, Kwang-Tsao | name-list-style = amp | year = 2007 | title = Molecular phylogeny of Chaetodon (Teleostei: Chaetodontidae) in the Indo-West Pacific: evolution in geminate species pairs and species groups | journal = Raffles Bulletin of Zoology Supplement | volume = 14 | pages = 77–86 | url = http://rmbr.nus.edu.sg/rbz/biblio/s14/s14rbz10_Hsu-pp77-86.pdf | access-date = 2008-09-01 | archive-date = 2007-08-11 | archive-url = https://web.archive.org/web/20070811042056/http://rmbr.nus.edu.sg/rbz/biblio/s14/s14rbz10_Hsu-pp77-86.pdf | url-status = dead }}
